why change in state takes place at constant temperature
Answers
Answer:
The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings. ... That's because a thermometer measures temperature, and temperature is the average kinetic energy of the particles of matter.
During the phase change from liquid to gas, the added heat is stored in the molecules as, once again, potential energy, and the temperature remains constant. The added heat is used to overcome the remaining forces that hold the molecules together within the liquid.
Answer:
Change in state takes place at constant temperature because of latent heat as the heat absorbed gets used in breaking of bonds between molecules and therefore there is no rise in temperature
Explanation:
Latent heat is the constant temperature at which sa substance changes its state
