(a)
The energy in calories needed to raise the temperature of 1 gram of water by 10C
(a)
Answer to Problem 16A
The heat needed is 1 Calorie.
Explanation of Solution
Given info:
The amount of water m = 1 g
The change in temperature of water
The specific capacity of water Cw= 1 Cal/g 0C
Let Q is the heat energy absorbed by water.
Formula used:
Calculation:
Substituting the given values, we get
Conclusion:
Thus, the energy absorbed by 1g water to raise the temperature of 1 gram of water by 10C is
1 calorie.
(b)
The energy in calories needed to melt1 gram of water at 00C
(b)
Answer to Problem 16A
The heat needed is 80 Calories.
Explanation of Solution
Given info:
The amount of water m = 1 g
The latent heat of fusion of water Lf= 80 Cal/g
Let Q is the heat needed.
Formula used:
Calculation:
Substituting the given values, we get
Conclusion:
Thus, the energy in calories needed to melt 1 gram of ice 00C is 80 calories.
(c)
The energy in calories needed to vaporize1 gram of water at 1000C
(c)
Answer to Problem 16A
The heat needed is 540 Calories.
Explanation of Solution
Given info:
The amount of water m = 1 g
The latent heat of vaporization of water Lv= 540 Cal/g
Let Q is the heat needed.
Formula used:
Calculation:
Substituting the given values, we get
Conclusion:
Thus, the energy in calories needed to vaporize 1 gram of water at 1000C is 540 calories.
