Posted by Avanish A 2 years, 3 months ago

CBSE > Class 09 > Science

3 answers

Pt Arnav Sharma 2 years, 3 months ago

During the change of state of matter the supplied heat remains constamt because it is being utilised by the particles of matter to overcome the force of attraction

Avanish A 2 years, 3 months ago

Thanks for the answer

Akshra Akshu 2 years, 3 months ago

due to the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance hence the temperature stays constant.
