Question

Determine

how much

energy in kJ would be transferred if 300.0 grams

of steam (gaseous

water) at 150.0

̊C

is cooled to ice

(solid water)

at -20.0

̊C.

The specific

heat

of steam is

1.86

J/(g∙ ̊C),

the

specific heat

of ice is 2.06

J/(g∙ ̊C),

the heat of fusion of water

is 333

J/g, and

the heat

of vaporization is 2256 J/g.
