<u>Answer:</u> The amount of heat absorbed is 141.004 kJ.
<u>Explanation:</u>
In order to calculate the amount of heat released while converting given amount of steam (gaseous state) to ice (solid state), few processes are involved:
(1):
(2):
(3):
(4):
Calculating the heat absorbed for the process having the same temperature:
......(i)
where,
q is the amount of heat absorbed, m is the mass of sample and is the enthalpy of fusion or vaporization
Calculating the heat released for the process having different temperature:
......(ii)
where,
= specific heat of solid or liquid
are final and initial temperatures respectively
- <u>For process 1:</u>
We are given:
Putting values in equation (i), we get:
- <u>For process 2:</u>
We are given:
Putting values in equation (i), we get:
- <u>For process 3:</u>
We are given:
Putting values in equation (i), we get:
- <u>For process 4:</u>
We are given:
Putting values in equation (i), we get:
Calculating the total amount of heat released:
(Conversion factor: 1 kJ = 1000J)
Hence, the amount of heat absorbed is 141.004 kJ.
