When water at 4 degrees C is heated it expands if it is instead cooled it will?
Explanation: 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.

Can a sample of water possibly have the same volume after being warmed by several Celsius degrees?
water expands when freezing. Can a sample of water possibly have the same volume after being warmed by several Celsius degrees? less than 30 degrees C. They both have to equal the same temperature by the end of the heat transfer.
What happens when water at 4 degree celsius is heated for the?
Though liquids expand on heating, water does not expand between 0°C to 4°C instead it contracts as water has maximum density at 4°C. It expands above 4°C.
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%.
What happens when water at 4 C is heated further?
Though liquids expand on heating, water does not expand between 0°C to 4°C instead it contracts as water has maximum density at 4°C. It expands above 4°C.
What happens to a sample of water when it is heated between 0 C and 4 C quizlet?
A temperature of degrees 5 Fahrenheit is equivalent to _____ Kelvin. What happens to a sample of water when its temperature is reduced between 0°C and 4°C? Its density increases. It vaporizes.
What happens to water when it reaches 4 degrees Celsius?
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%.
Which expands more when the temperature is increased?
In general, liquids will expand more than solids with an equal increase in temperature. Similarly, in general, gases will expand more than liquids with an equal increase in temperature. Solids also expand, but not as much as liquids or gases because their particles are fixed in position.
Why do substances expand when their temperature is increased?
Substances expand when their temperature increases because the molecules have more energy and move faster and farther apart.
What happens to the temperature if more heat is added?
Usually, when you add energy to a bunch of atoms they move faster and get hotter. Similarly, if you remove energy from a bunch of atoms, they usually move less and get cooler. Because adding heat energy usually results in a temperature rise, people often confuse heat and temperature.
When water is cooled from 4 degree celsius to zero degree celsius it will?
When water is cooled from 4°C to 0°C, its density decreases. The anomalous expansion of water helps preserve aquatic life during very cold weather.
When water is heated from 0 C to 4 C the volume of water?
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.
What happens when water at 4 degree Celsius is heated for the?
Though liquids expand on heating, water does not expand between 0°C to 4°C instead it contracts as water has maximum density at 4°C. It expands above 4°C.
When water is cooled below 4 degrees Celsius what is it called?
When water is cools below 4oC, its density decreases, hence volume increases.
When water is cooled from 4 degree Celsius to zero degree Celsius it will?
When water is cooled from 4°C to 0°C, its density decreases. The anomalous expansion of water helps preserve aquatic life during very cold weather.
At what temperature does water have the greatest density?
four degrees Celsius In almost all substances the atoms and molecules move closer together as they get colder. They then solidify. Water, however, attains its greatest density at four degrees Celsius because the water molecules are packed closest together at this temperature.
When a material is found to have a definite volume and definite shape and when it doesn’t require a container to maintain its shape what is the phase of the material?
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.
Why does water expand below 4 degrees?
Overview. Below 4°C, the hydrogen bonds between water molecules become stronger and cause the matter to expand. Because the bonds between water molecules are stronger, they are less likely to break and re-form as they do in the liquid state.
Why does water expand when cooled?
When water freezes, its molecules get arranged in a crystalline structure, thereby attaining a defined shape. This crystalline structure is less dense, and since there are gaps between individual molecules in the structure, the overall volume increases and water 'expands'.
Does water expand when heated?
When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense.
Does heat or cold expand?
Most matter expands when heated and contracts when cooled, a principle called thermal expansion. The average kinetic energy of the particles increases when matter is heated and this increase in motion increases the average distance between its atoms.
Why does all the water in a lake have to be cooled to 4 C before the surface water can be cooled below 4 C?
Why does all the water in a lake have to be cooled to 4°C before the surface water can be cooled below 4°C? Water has a low specific heat at 4°C, which allows it to cool rapidly and freeze. When water is cooled to 4°C, it sinks, cooling all the water in the pond to 4°C as it sinks.
Why do things expand when heated and contract when cooled?
Most matter expands when heated and contracts when cooled, a principle called thermal expansion. The average kinetic energy of the particles increases when matter is heated and this increase in motion increases the average distance between its atoms.
What happens to the temperature of the water when heated?
For instance, when water is boiling, adding heat does not increase its temperature. This happens at the boiling temperature of every substance that can vaporize. At the boiling temperature, adding heat energy converts the liquid into a gas WITHOUT RAISING THE TEMPERATURE.
What changes take place when water is heated or cooled?
When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense.
When water is heated from 0 degrees Celsius to 4 degrees Celsius what is its 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.
What will happen when water is heated from 0 C to 4 C explain?
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.
What happens to a given volume of water as it is cooled from 4 C to zero?
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%.
