States need regulations on energy to save the country money. The US is in debt about $13 trillion so they need to save energy to save money. With the regulations, states will be supported with grants, and this will help the value of the dollar go up. It also saves the environment.
Melting solid into liquid requires energy to be added to the substance.
energy.
Yes, vaporizing requires an input of energy to heat the substance to its vaporization point. This energy causes the substance to change from a solid or liquid state to a vapor or gas state.
The change of state from gas to liquid (condensation) or from liquid to solid (freezing) requires matter to lose heat energy in order to transition to a more ordered state. Heat energy must be removed to allow the particles to slow down and come closer together, changing their arrangement.
Hi, by this I assume you mean that you want to know which changes of state produces heat (raise the air temperature) as this temperature change is the removal of energy from the system. (Also called an exothermic reaction).To remove energy from a change of state bonds must be formed between molecules therefore going from gas to liquid, gas to solid or liquid to solid are all exothermic and remove energy from the system.If you mean removal of energy from the air therefore decreasing air temperature then it is the other way around.

Yes, that's correct.
Changing a chocolate from soild to liquid requires the absroption of energy.

A temperature change requires as gain or loss of heat energy.
energy is required
Quite often, the temperature doesn't change. For example: if you melt ice, you convert ice at 0 °C to water at 0°C. You need to put heat energy into the ice to melt it, but its temperature doesn't change. (The change of state itself requires energy - this is a type of potential energy.)
Melting typically requires energy. The energy is used to overcome the forces holding the particles together in a solid state so they can move and slide past each other in the liquid state.
The change from solid to liquid, liquid to gas, and solid to gas all require an input of energy to overcome intermolecular forces holding the particles together. This added energy breaks these forces, allowing the particles to move more freely and change state.
