Question

Which statement is wrong?

1. Temperature measures the average kinetic energy of random motion, but not other kinds of energy.

2. When the same amount of heat produces different changes in temperature in two substances of the same mass, we say that they have different specific heat capacities.

3. Each substance has its own characteristic specific heat capacity.

4. Different substances have different thermal properties due to differences in the way energy is stored internally in the substances.

5. Adding the same amount of heat to two different objects will produce the same increase in temperature.

Answer 1

The Fifth statement is incorrect.

" 5. Adding the same amount of heat to two different objects will produce the same increase in temperature. " is INCORRECT.

This is because, " an increase in temperature for an body/Object depends on many factors such as the specific heat capacity, Thermal conductivity/Diffusivity of that material, the nature of that material etc... ".

The specific Heat capacities, coefficient of thermal conductivity/diffusivity, and the nature of material are the UNIQUE PROPERTY OF EACH AND EVERY MATERIAL. and hence, even if same amount of heat applied on different materials, the produced amount of heat will always be different.

Hence, The Fifth statement is incorrect !
