How many joules of heat are needed to raise the temperature of 5.0 g of aluminum from 22°C to 32°C, if the specific heat of aluminum is 0.90 J/g°C .

Heat, Q = 45 J

Explanation:

We have,

Mass of aluminium is 5 g

The temperature is raised from 22°C to 32°C.

The specific heat of aluminium is 0.90 J/g°C.

It is required to find the heat are needed to raise the temperature.

The heat required to raise the temperature is given by :

So, 45 J of heat are needed to the temperature of 5.0 g of aluminum from 22°C to 32°C.
