Question

A 36-gram of water has an initial temperature of 22. After the sample absorbs 1200 joules of heat is the final temperature of the sample is

Answer 1

Q = m * C * ΔT

1200 = 36 * 4.18 * ΔT

1200 = 150.48 * ΔT

ΔT = 1200 / 150.48

ΔT = 8

8 = Tf - 22

Tf = 22 + 8

Tf = 30ºC

hope this helps!
