Please someone answer, I will mark them who answers as brainliest, How much energy is needed to heat 100 kg of paraffin from 10 degree Celsius to 30 degree Celsius. The specific heat capacity of paraffin is. 2200 unit.

40,000J

Explanation:

The heat energy required to raise the temperature of unit mass of substance through unit degree is called specific heat of substance . As given 2000J energy is needed to heat 1 kg of paraffin through 1

o

C, therefore specific heat of paraffin will be 2000J/kg−

o

C.

Now, heat energy required to raise the temperature of mass m of substance (specific heat c) through Δt is given by ,

Q=mcΔt,

Given: m=10kg,Δt=2

o

C,c=2000J/kg−

o

C

Q=10×2000×2=40,000J

yup its correct its: c) b b

think its the third option
