Question

The number of joules needed to raise the temperature of 32 g of water from 12 °C to 54 °C is

The specific heat of water is 4.184 J/g °C.

Answer 1

Answer: 5,600 J

Step-by-step explanation:

Joules = mass x specific heat x temperature change

32 x 4.184 x (54 - 12)

= 133.888 x 42

= 5,623.296

(significant figures => 5,600)
