Question

When water boils and is converted into steam, then (a) heat is taken in and temperature remains constant



b.Heat is taken in and temperatures rises (c) heat is given out and temperature lowers (d) heat is given out and temperature remains constant?

Answer 1

d) HEAT IS GIVEN OUT AND TEMP. REMAINS CONSTANT

This is because of latent heat of vaporization i.e hidden heat.

This heat is used in breaking the intermolecular force of attraction in water to change liquid to gas. Therefore temp. remains constant but heat is given out.

Answer 2

Answer:

d) heat is given out and temperature remains constant
