Question

This question pertains to a situation in which you bring 10 g of substance X at 35 °C into contact with 10 g of substance Y at 25 °C.

SUBSTANCE	X	Y
T (vaporization)	2250 °C	78.4 °C
T (fusion)	29.8 °C	–131 °C
ΔH° (fusion)	+11.4 J/g	+98.9 J/g
C (solid)	0.37 J/g °C	2.38 J/g °C
C (liquid)	0.49 J/g °C	2.64 J/g °C

How much energy is released by the 10 g of liquid substance X freezing into a solid at 29.8 °C? Express your answer as a positive quantity in Joules rounded to the nearest whole number.
