166. Two bodies A and B are of same mass and same amount of heat is given to both of them.
     If the temperature of A increases more than that of B because of heat addition, then.

1. 1. The specific heat capacity of A is more than that of B

   
   
   

   2. The specific heat capacity of A is less than that of B

   
   
   

   3. Both A and B have the same specific heat capacity but A has greater thermal conductivity

   
   
   

   4. Both A and B have the same specific heat capacity but B has greater thermal conductivity

170. The temperature of water at the bottom of a waterfall is higher than that at the top because

1. 1. Water at the bottom has greater potential energy

   
   
   

   2. The surface at the bottom provides heat

   
   
   

   3. Kinetic energy of falling water is converted into heat

   
   
   

   4. Falling water absorbs heat from the surroundings
