How many joules are released when 30.0 g of H2O(g) condenses at 100°C and cools to 10°C

Heat released : 79086 J

Condenses :

1. phase change (gas - liquid) : heat of vaporization (ΔH vap for water = 2260 J/g)

2. cools from 100 - 10 : (Q=m.cΔT)

1. Q=m.ΔH vap

2. Q=mc.ΔT(c water = 4.18 J/g C)

Q tot = 67800 + 11286 = 79086 J

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

the answer is   c.) 1575 j.
