Question

Which statement is wrong?

1. Each substance has its own characteristic

specific heat capacity.

2. Adding the same amount of heat to two

different objects will produce the same increase in temperature.

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

kinds of energy.

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

5. 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.

Answer 1

The same amount of heat does not necessarily produce the same increase in temperature in different objects. For example, increase in temperature depends on specific heat capacity of the substance.

Answer: 2. Adding the same amount of heat to two different objects will produce the same increase in temperature.
