B)If the bag of chips in the above questions had been burned and used to heat water from 13degrees celcius to 20 degress celcius, then how much water was being heated(assuming 100%energy conversion)

**2. Homework Equations**

Eout/Ein*100%

**3. The Attempt at a Solution**

m=60.0kg

Efficiecny=24%

P=325 W
