1)
During phase change, average kinetic energy of the molecules of the substance
Increases
Decreases
Remains the same
Doubles
2)
In the part of the transition curve where the temperature decreases,
the kinetic energy decreases while the potential energy stays the same
the potential energy decreases while the kinetic energy stays the same
kinetic energy as well as potential energy changes
None of these
3)
The amount of energy needed to melt 'm' gram of a solid substance to its liquid form is
Q= mCdT, where C is the Specific heat capacity of the substance
Q=mLf ,where Lf is the Latent heat of fusion of the substance
Q=ÃÆ’A(T24-T14)∆t, where T1 and T2 are the temperatures of the body and the surroundings
None of these
4)
Heat exchanges are generally governed by
Newton’s law of cooling
Stephan’s law
Planck’s law
Law of conservation of energy
5)
The specific heat capacity of water is
333KJ/KgK
2.108 KJ/KgK
670 KJ/KgK
4.187 KJ/KgK
