8 Explain the role of latest hest in
the change of state of a substances
Answers
Answer:
During the phase change of a substance, its temperature does not increase and hence its kinetic energy. ... Thus, the heat supplied during phase transformation is used up in increasing or decreasing the potential energy and this heat energy is known as latent heat.
Answer:
It requires energy for a solid to melt into a liquid. Every pure substance has a certain amount of energy it needs to change from a solid to a liquid. This amount is called the enthalpy of fusion (or heat of fusion) of the substance,
Energy is always involved in changes of state. Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. For a solid to change to a liquid, matter must absorb energy from its surroundings.
