# How much energy is needed to raise the temperature of 2.0 g of water by 5.0°C?

##### 1 Answer

#### Explanation:

The equation for working out the amount of thermal energy required is

In this case, the mass is 2.0g, the specific heat capacity of water is 4.18J/g/K, and the change in temperature is

This is only theoretical though, in the real world a lot of heat would be lost to the surroundings, so it would require more energy than this.
