Activity 8: Thermal Fynansion and Heat

Answer 2

• As we know that thermal expansion is the ability of an object that can change its shape, area, and volume.

• The object can change in response to a change in temperature.

• If the temperature is increased, the volume also increases.

• From the question the correct answer is as follows:

     1. YES,  thermal expansion is occurring, car tire has exploded due

                  to the increase in temperature

     2. NO, thermal expansion is not done here.

     3. YES, thermal expansion is occurring, when hot water is poured into

                  a glass it will crack due to an increase in temperature.

     4. NO, thermal expansion is not done here.

     5. NO, thermal expansion is not done here.
