The amount of heat needed to change
Answer to Problem 10PEA
The amount of heat needed to change
Explanation of Solution
To change the water at
One is the heat required to raise the temperature of water and the other one is the heat required to cause the phase change of water.
Write the expression for the total heat required.
Here,
Write the expression for the heat required to raise the temperature.
Here,
Water completely changes to steam. Hence, the mass of water is same as the mass of steam.
Write the expression for the heat required to change the phase into steam.
Here,
Write the expression for the change in temperature.
Here,
Conclusion:
Substitute
Substitute
Substitute
Substitute
Therefore, the amount of heat needed to change
