Is it true that evaporation and condensation take place when water gains heat energy?
Evaporation is an endothermic process.Condensation is an exothermic process.
What takes place when liquid absorbs energy and changes to a gas?
It be evaporation. ~answered by FightingLucario
What bonds of the reactants are broken in this reaction?
Energy is the key for any reaction to take place. To break the bonds of a substance, a fixed amount of energy is required which is called bond energy. For some substances the bond energy is low and they do not require external energy and start reaction on their on there own whereas for some substances we have to provide external energy for the reaction to take place.
How do catalysts affects the energy of a reaction?
They lower the activation energy required for the reactions to take place
Where does evaporation take place in a liquid?
Evaporation takes place at the surface of a liquid. (There is an article about evaporation on Wikipedia that may be helpful if you have any more questions about evaporation.) ~KKMG1
Is energy released or required for sublimation to take place?
Required
Is it true that evaporation and condensation take place when water gains heat energy?
Evaporation is an endothermic process.Condensation is an exothermic process.
Evaporation of water takes place as a result of the?
energy of moving water molecules
Can you compare evaporation and condensation?
Evaporation is the process in which there is a change of state from liquid to gas. Condensation it is the process in which there is a change of state from gaseous to liquid or solid. Evaporation takes place from surfaces, all the time at all places Condensation can take place on surfaces, or at any place in a gas, though it is often aided by the presence of dust or other small particles. Evaporation absorbs energy. Condensation gives out energy.

Why does the evaporation of sweat cool your body on the warm day?
Evaporation is the vaporization that takes place only on the surface of a liquid. Evaporation takes up energy - and it takes up that energy from the warm surface of your skin. Thus, when sweat evaporates, it takes heat from your skin, cooling it.
Can evaporation take place in any temperature?
yes, evaporation can take take place at all temperatures. the energy among the molecules of liquids is not equally distributed.the molecules of high energy ,when reach the surface of liquid ,escape into the enviornment , leaving behind the low energy molecules . thus evoporation has take place.
How do catalysts the energy of reactions?
They lower the activation energy required for the reactions to take place
Where is the energy and how is energy released in ATP?
in a pond or a grassy place
What is different between exothermic and endothermic reactions?
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.

Why does evaporation cool water?
During evaporation molecules of water leave the water surface and go into solution in the air. The temperature of the water is causes by the vibration of the molecules in it (micro kinetic energy). During evaporation it is the molecules with the biggest vibration that have the energy to leave the surface into the air. Thus the overall vibration energy of the water reduces and this means the temperature falls. Note however that energy can not actually be lost, so the energy taken out of the water by the departing molecules remains in water vapour in the air. When this vapour condenses back into water the energy is released, warming the place where it condenses. This energy is called latent heat (the latent heat of evaporation/condensation) and this ability to transfer heat form one place to another in a vapour phase is how a fridge works.
