fusion.
temperature.
radiant heat.
specific heat.

Answer 1

Answer on Question #51923-Physics-Field Theory

The amount of heat necessary to change an object's temperature $1\,\mathrm{kg}\,1{}^{\circ}\mathrm{C}$ is called

- fusion.

- temperature.

- radiant heat.

- specific heat.

Solution

Specific heat is the amount of heat (energy) required to raise the temperature of an unit mass of a certain substance by an unit temperature interval:

$$C = \frac{\Delta Q}{m \Delta T}.$$

In our case $m = 1\,\mathrm{kg}$ and $\Delta T = 1{}^{\circ}\mathrm{C}$.

Answer: specific heat.
