A 25.0 g sample of metal at
Nadya [2.5K]

The change in temperature of the metal is 6.1°C. Details about change in temperature can be found below.

<h3>How to calculate change in temperature?</h3>

The change in temperature of a substance can be calculated by subtracting the initial temperature of the substance from the final temperature.

According to this question, a 25.0 g sample of metal at 16.0 °C is warmed to 22.1 °C by 259J of energy.

This means that the change in temperature of the metal can be calculated as:

∆T = 22.1°C - 16°C

∆T = 6.1°C

Therefore, the change in temperature of the metal is 6.1°C.
