Question #9859e

Oct 2, 2017

Use the formula $Q = m \cdot c \cdot \Delta T$ and solve for $\Delta T$ - that is the change in temperature.

Explanation:

The formula that applies in such a case is $Q = m \cdot c \cdot \Delta T$ where

• Q is positive energy if heat is gained by the mass and negative energy if heat is lost
• m is the mass of the material being heated or cooled
• c is called specific heat - it is a characteristic of the material of the mass
• $\Delta T$ is the temperature change from the starting temperature - if negative, the mass was cooled.

For example:
The specific heat of water is about $4.186 \frac{k J}{k g {\cdot}^{\circ} K}$. If you gave 4.186 kJ to 1 kg of water, its temperature would increase ${1}^{\circ} K$. A change of ${1}^{\circ} K$ is equivalent to a change of ${1}^{\circ} C$.

I hope this helps,
