What makes water a liquid at room temperature?
Water at room temperature is liquid due to the presence of hydrogen bond. These bonds hold water molecules together for small fractions of a second.
Why should water really be a gas at room temperature and not a liquid?
Water molecules are strongly attracted to each other, so they remain condensed (that is, a liquid, and not a gas) at higher temperatures. Dihydrogen and dioxygen have no strong attractive forces to hold the molecules together, so they exist as gases at room temperature and pressure (that is, in our everyday lives).
What makes methane a gas at room temperature?
Unlike water molecules, which are polar and attract one another, methane molecules are non-polar and do not have much attraction for one another. This is the reason why, at room temperature, methane is a gas while water is a liquid.
Why is water a liquid at room temperature instead of a gas quizlet?
why is water a liquid at room temperature instead of gas? The attraction of the hydrogen bonds keeps the molecules close enough together to be a liquid at room temperature.
Why is water liquid at room temperature Brainly?
Water is liquid at room temperature because- Everywhere from 0°C to 100°C, at room temperature water is found in liquid state.
Why is water a liquid at room temperature quizlet?
room temperature? It is liquid because of hydrogen bonding. When water is a liquid its molecules are closer than when it is a solid.
Is methane a liquid or gas?
gas methane, colourless, odourless gas that occurs abundantly in nature and as a product of certain human activities. Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases. Its chemical formula is CH4.
What is methane at room temperature?
At room temperature and pressure, methane is a colorless, odorless gas, lighter than air.
What makes water a liquid at room temperature quizlet?
room temperature? It is liquid because of hydrogen bonding. When water is a liquid its molecules are closer than when it is a solid.
What makes water h2o a polar molecule?
The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles – a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.
Why an almirah is solid at room temperature?
(b) An iron almirah is a solid at room temperature because the melting point of iron is higher than room temperature i.e. more then 1500oC.
What is the room temperature?
The American Heritage Dictionary of the English Language identifies room temperature as around 20–22 °C (68–72 °F), while the Oxford English Dictionary states that it is "conventionally taken as about 20 °C (68 °F)".
Why is oxygen a gas at room temperature?
Water molecules like to form stacked alternating chains of Vs. The high temperature will shake these chains, but at room temperature, the water molecules are very viscous between them, they remain liquid, only a few water molecules evaporate accidentally, while oxygen molecules, without this viscosity, remain gaseous.
How is methane gas turned into a liquid?
Methane must be cooled below its critical temperature of -82.3 °C in order to be liquified under pressure. Because of the associated cryogenic apparatus, LNG tankers are used for transport. Methanol is a conveniently handled combustible liquid, but its energy density is half of that of gasoline.
Is methane a gas?
Methane (CH4) is a hydrocarbon that is a primary component of natural gas. Methane is also a greenhouse gas (GHG), so its presence in the atmosphere affects the earth's temperature and climate system. Methane is emitted from a variety of anthropogenic (human-influenced) and natural sources.
Is methane a polar or nonpolar molecule?
non-polar molecule Methane is non-polar molecule because of its symmetrical tetrahedral structure.
Why is water polar and non polar?
The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles – a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.
What is the normal room temperature class 9?
Answer. Explanation: The average room temperature is typically around 20°C, or 68 degrees Fahrenheit.
Why water is a liquid and an iron rod solid at room temperature?
(a) Water at room temperature is a liquid because its freezing point is 0 °C and boiling point is 100 °C. (c) An iron almirah is a solid at room temperature because melting point of iron is higher than room temperature.
What is room temperature water called?
dictionary.reference.com/browse/tepid: moderately warm; lukewarm: tepid water. I've never heard of tepid being used to refer to blood-temperature :/ – Matt. Feb 13, 2013 at 17:47.
What is room temperature water?
Room temperature water comes in at around 78 F (25.55 C).
Why water is liquid while oxygen is gas?
At room temperature, oxygen is a gas and water is a liquid because the force of attraction between oxygen molecules is less than the force of attraction between water molecules.
Which is a gas at room temp?
Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).
What temperature does methane turn into liquid?
The intermolecular forces between the very small molecules of methane (CH4) are very weak. Methane cannot be condensed to a liquid by pressure at ordinary temperatures because the critical temperature3 of methane is −82.1 ºC. Above this temperature no liquid phase exists.
What makes up methane gas?
Methane is a chemical compound with the molecular formula CH4. It is the main component in natural gas. Methane is considered the simplest of alkanes, compounds that consist only of hydrogen (H) and carbon (C) elements. Methane is an odorless, colorless, tasteless gas that is lighter than air.
What is liquid methane?
(′lik·wəd ′meth‚ān) (cryogenics) Methane that has been cooled to at least -161°C; used for cryogenic applications and for tankship transport of methane.
Why is methane nonpolar and water is polar?
Methane Does not have the charges present at the end because of finely distributed electrons and this distribution which is symmetrical cancel out each other. Hence it is non-polar.
Is methane soluble in water?

What makes water polar?
The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles – a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.
What is Indian room temperature?
Typically, room temperature is set between 20-21 degree Celsius whereas, as per standard comfort conditions, ideal temperature is 24-25 degree Celsius.
