# How much energy is needed to change the temperature of 95.4g of nickel from 22°C to 32°C? Is the energy absorbed or released?

## The specific heat of nickel is 0.44 J/g°C.

$4.20 \cdot {10}^{2} J$ of energy are required to raise the temperature of this substance by 10°C.

#### Explanation:

Here, we're relating a few things: (1) the mass of the substance, (2) its specific heat, and (3) the temperature change, in the following equation:

$q = m {C}_{s} \Delta T$

q = 95.4g* (0.44J)/(g*°C)* 10°C
$q \approx 4.20 \cdot {10}^{2} J$
