Question

How much heat do you need to raise the temperature of 150 g of gasoline from -30 degrees C to -15 degrees C? I cannot see the tinycurl

Answer 1

q = mCpΔT

Cp = 2.22 J/g°C
m = 150 g
ΔT = T(final) - T(initial) = -15°C - (-30°C) = +15°C

q = (150 g)(2.22 J/g°C)(15°C) = 4,995 J

Answer 2

5.00 kj
