Answer:
I found: 1700J
Explanation:
here you have a change of phase from liquid to solid where we can evaluate the heat released Q (in Joules) using:
Q=mLs
where m= mass=
Ls= latent heat of solidification of water that from literature is: 3.5×105J /kg
so for 5g=0.005kg of water, we get:
Q=0.005⋅3.4×105=1700J
