Question

question 3 of 20 which change in an object will decrease its thermal energy? a. an increase in either mass or temperature b. an increase in either mass or velocity c. a decrease in either mass or temperature d. a decrease in either mass or velocity

Explanation:

Thermal energy of an object is related to its mass and temperature. The formula for thermal - energy (heat energy) is $Q = mc\Delta T$, where $m$ is mass, $c$ is specific heat capacity and $\Delta T$ is the change in temperature. A decrease in mass or temperature will lead to a decrease in thermal energy.

Answer:

C. A decrease in either mass or temperature
