In terms of particles how evaporation causes hot water to cool?

Description : In terms of particles how evaporation causes hot water to cool?

Last Answer : For a molecule of water to change from a liquid to a gas requires it absorb heat, called the heat of vaporization. Evaporation is the conversion from a liquid (water) to a gas (water vapor), so each molecule that evaporates takes the heat of vaporization with it making the remaining water cooler.

When heat is removed, particles in a solid, liquid, or gas do what?

Description : When heat is removed, particles in a solid, liquid, or gas do what?

Last Answer : State Changes If you give the particles energy; or take energy away from them; then you can change their state. If you heat up a solid - you give it some energy. This causes the particles to move more and ... into a liquid, or melt. If the liquid is heated then it may evaporate and turn into a gas.

Description : Explain the effect of increasing the temperature of a liquid, on intermolecular forces operating between its particles. What will happen to the viscosity of a liquid if its temperature is increased? Arrange the following in increasing order of viscosity-water, hexane, glycerine.

Last Answer : Ans. On increasing the temperature , the kinetic energy of liquid molecules increases so that it can overcome the attractive forces between the molecules and hence liquid can flow more easily i.e. viscosity decreases. Order of increasing viscosity : hexane < water < glycerine.
