Question

The internal thermal energy of the steel body is 10 kJ at 0 ° C. According to one
of the same and the same mass of steel body the thermal energy is 25 kJ. What is the temperature of this second body?

Answer 1

Solution

If 10 kJ correspond to 273 K

Then 25 kJ correspond to X, where

$$X=25∗273/10=682.5K=409.5°C$$

Answer

409.5 °C is the temperature of this second body.
