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
