Answer:

[tex]Q=4704000J\\Q=4.7MJ[/tex]

Explanation:

Given data

Heat capacity c=4.2 J/gC

Water weigh m=1000g

Temperature Risen T=20°C to 90°C

To find

Heat Q

Solution

The formula to find Heat is:

Q=mcΔT

Where

m is mass

c is heat capacity

ΔT is change in temperature

So

[tex]Q=4.2(16*1000)*(90-70)\\Q=4704000J\\Q=4.7MJ[/tex]
