Which of the following normally warms up faster?
Iron warms up faster when heat is applied.
Which of the following expands more when the temperature is increased?
Helium 6. Which of the following expands most when temperature is increased? Reasoning: Helium expands more because it is a gas.
When water at 4 C is heated it expands if it is instead cooled it will?
A: 4 degrees C turns out to be the temperature at which liquid water has the highest density. If you heat it or cool it it will expand. The expansion of water when you cool it to lower temperatures is unusual since most liquids contract when they're cooled.
Which is greater an increase in temperature of 1 Celsius degree or an increase of 1 Fahrenheit degree quizlet?
A change in temperature of 1 Celsius degree is greater than a temperature change of 1 Fahrenheit degree because a Celsius degree is larger than a Fahrenheit degree.
When a volume of air is compressed and no heat enters or leaves the air temperature will?
When a volume of air is compressed and no heat enters or leaves, the air temperature will: will increase (adiabatic compression) no heat enters or leaves system; work is done on the system by compression.
Which of the following forms of energy is most closely related to temperature?
Thermal energy and temperature are closely related. Both reflect the kinetic energy of moving particles of matter. However, temperature is the average kinetic energy of particles of matter, whereas thermal energy is the total kinetic energy of particles of matter.
What expands equally on equal rise in temperature?
All gases expand equally for equal rise in temperature.
Which of the following generally expands more for an equal increase in temperature solids or liquids?
In general, liquids will expand more than solids with an equal increase in temperature.
Does water expand or contract when it is cooled from 4 C to 0 C?
Water is one of the few exceptions to this behavior. When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.
When water at 4c is heated it expands when water at 4c is cooled it?
A: 4 degrees C turns out to be the temperature at which liquid water has the highest density. If you heat it or cool it, it will expand. The expansion of water when you cool it to lower temperatures is unusual, since most liquids contract when they're cooled.
Which is greater an increase in temperature of 1 Celsius degree or an increase of 1 Fahrenheit?
Therefore, a temperature difference of one degree Celsius is greater than a temperature difference of one degree Fahrenheit. Since 100 Celsius degrees span the same range as 180 Fahrenheit degrees, one degree on the Celsius scale is 1.8 times larger than one degree on the Fahrenheit scale (because 180100=95=1.8).
What happens when compressed air expands?
The combination law explains what happens to air when it's compressed into a smaller volume. It tells us that when air is compressed, the air's pressure and temperature increase as the volume of the space containing air decreases. By pushing air into a smaller space, we force it to become hotter and more pressurized.
When the gas expands under adiabatic conditions its temperature?
In the adiabatic expansion of the gas, the work done by the gas is always positive. Since the work done by the gas is positive the internal energy decreases, so the temperature of the gas also decreases.
Which of the following is most closely related to kinetic energy of molecules?
Final Answer: The average kinetic energy of the particles of a gas is most closely associated with (B) temperature.
What is kinetic and thermal energy?
Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy.
Which of the following will expand the most for same rise in temperature D All will expand same a Aluminium C Wood B glass?
(c) Gas will expand more as the inter-molecular force of attraction in gas molecules is least and K.E. is maximum.
Why all gases have equal coefficient of volume expansion?
The molecules of all gases do not have cohesive force amongst themselves. During cubical expansion molecules of all types of gases are separate from each other under similar conditions. Hence, all gases show equal expansion on being heated for same range of temperature at a constant pressure.
Which will expands more solid liquid or gas?
Solution: Gases expand much more than the liquid and the solids. Like liquids, the gases do not have a definite shape, so they also have only the cubical expansion.
When water is heated from 0 to 4 What is the volume?
Water has a unique property of anomalous expansion. When water is heated from 0oC to 4oC it contracts continuously instead of expanding. That means its volume decreases upto 4oC.
Does water expand at 4 degrees C?
Water is one of the few exceptions to this behavior. When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.
When water is heated from 0c to 10c its volume?
decreases It contracts on heating between 0oC and 4oC , so the volume of the water decreases.
Which is greater an increase in temperature of 1 Celsius degree or an increase of 1 Fahrenheit degree an increase of 1 F is larger an increase of 1 C is larger the same?
Therefore, a temperature difference of one degree Celsius is greater than a temperature difference of one degree Fahrenheit. Since 100 Celsius degrees span the same range as 180 Fahrenheit degrees, one degree on the Celsius scale is 1.8 times larger than one degree on the Fahrenheit scale (because 180100=95=1.8).
Why does air expand as expands?
A rising parcel of air expands because the air pressure falls with elevation. This expansion causes the air to cool. A falling parcel of air contracts because the air pressure increases.
When a gas expands what happens to its temperature?
As a gas (like air) expands, the value of V increases and this has the effect of increasing T (The temperature). As the energy needed to increase it's temperature must be supplied from somewhere, the gas takes the energy from the surrounding system giving the effect of cooling.
What happens in adiabatic expansion?
Adiabatic expansion is defined as the expansion in which there is no heat interaction of the system with the surroundings and work is done by the system at the expense of its internal energy.
What happens isothermal expansion?
One condition, known as an isothermal expansion, involves keeping the gas at a constant temperature. As the gas does work against the restraining force of the piston, it must absorb heat in order to conserve energy. Otherwise, it would cool as it expands (or conversely heat as it is compressed).
What happens to the volume of a gas if its number of molecules increases while the pressure and temperature remain constant?
Avagadro's Law- Gives the relationship between volume and amount of gas in moles when pressure and temperature are held constant. If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases.
How is mechanical energy related to potential and kinetic energy?
As already mentioned, the mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.
How do you find thermal energy from kinetic and potential energy?

Which of the following will expand more when heated to the same temperature a solid B liquid or C gas?
(c) Gas will expand more as the inter-molecular force of attraction in gas molecules is least and K.E. is maximum.
