Question

How much heat is needed to raise the temperature by 10 0C of 5 kg of a substance of specific heat capacity 300 J/ (kg 0C)?

Answer 1

I got `15kJ`

Explanation:

The heat `Q` will be:

`Q=mcDeltaT`

with:

`m=5kg`
`c=300J/(kg^@C)`
`DeltaT=T_f-T_i=10^@C`

giving:

`Q=5*300*10=15,000J=15kJ`
