You do not change the identity of the materials.
During an exothermic change, energy is released from the substance in the form of heat to the surroundings. This results in a decrease in the internal energy of the substance, leading to a decrease in its temperature.
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
Energy loss is normally associated with a lowering of temperature and is a physical change. However, it can be caused by many other things such as nuclear change or chemical change, both of which are very different from each other and from temperature change.
The energy as heat is being used to increase or decrease the temperature of the pure substance. This process involves changing the internal energy of the substance without causing a phase transition.
Change in temperature directly indicates a change in the mean amount of kinetic energy possessed by each particle. It also indirectly indicates a possible change in state, and a possible change in chemical properties too (chemical reactions often involve energy transfer in the form of temperature change).

The heat of fusion is the energy required to change a substance from a solid to a liquid, while the heat of vaporization is the energy needed to change a substance from a liquid to a gas. Both are types of phase changes that require specific amounts of energy to occur.
Yes, the more substance you have, the slower the temperature change.
total thermal energy
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
the substance will become an entirley new substance.
This is referred to as conservation of energy
Energy transfer and temperature change are directly related. When energy is transferred to a substance, such as through heating, the temperature of the substance increases. The amount of temperature change depends on the amount of energy transferred and the specific heat capacity of the substance.
Latent heat is the energy absorbed or released during a phase change, such as melting or boiling, without affecting the temperature of the substance. Sensible heat, on the other hand, is the energy absorbed or released that does cause a change in temperature.
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
The equation for measuring the change in thermal energy is: Q = mcΔT, where Q is the change in thermal energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
