4.5 cm3 of water is boiled at atmospheric pressure to become 4048.3 cm3 of steam, also at atmospheric pressure. calculate the work done by the gas during this process. the latent heat of vaporization of water is 2.26 × 106 j/kg . answer in units of j. 006 (part 2 of 3) 10.0 points find the amount of heat added to the water to accomplish this process. answer in units of j.

1. 408.4 J

The work done by a gas is given by:

where

p is the gas pressure

is the change in volume of the gas

In this problem,

(atmospheric pressure)

is the change in volume

So, the work done is

2. 10170 J

The amount of heat added to the water to completely boil it is equal to the latent heat of vaporization:

where

m is the mass of the water

is the specific latent heat of vaporization

The initial volume of water is

and the water density is

So the water mass is

So, the amount of heat added to the water is
