4. The temperature of any substance remain constant during the change of state because the heat energy supplied is used up in changind the state of matter and also this heat is used for breaking of several bonds or attractive forces.This heat, which does not raise the temperature of the body, is called Laten heat.
5. Here the heat energy is used up in changing the state of matter. The heat is used to increase the kinetic energy of the particles of ice.
6. Iron is more electropositive than copper. It can displace Copper (Cu) from its salt Copper sulphate (CuSO4) and thus its colour changes from blue to green.
Fe + CuSO4 →FeSO4 + Cu
7. (I have told you earlier)
8. This happened because Steam have more latend heat of vaporisation than (boiling) water at 100°C.
Mark as brainliest if you got help from this.
Hope you would understand and score good in Chemistry.
Have a great day ahead.
