Radiation

7)Which of the following is a component of macroscopic energy?

      
Chemical energy

      
None of the given

      
Latent energy

      
Kinetic energy

      
Sensible energy

Answer 1

1) Negative kelvin temperature scale temperature is not possible ti measure (Absolute zero=273 K (or) 0K)...(b is correct)

2)Temperature is the intensive property (C is correct)

3)Insulated system can not exchange maatter and energy between system and surroundings.

4)A system is said to be in mechanical equilibrium if there is no force between system and surroundings,Therefore

none of given is correct.

5)Toal energy is the sum of Kinetic energy, potential energy (or) internal energy. Therefore none of given is correct.

6) The mode of heat transfer through a solid wall is conduction.

7)Kinetic energy is component of macroscopic energy.
