Answer to Problem 3E
10 cal.
Explanation of Solution
The specific heat capacity of water is
The calories of energy required to raise the temperature of 2 g of water by 5 oC can be calculated as follows:
Putting the values,
Thus, the amount of energy required is 10 cal.
(c)
Interpretation: The amount of calories of energy required to raise the temperature of 9 g of water by 35oC needs to be determined.
Concept Introduction:
The amount of energy transferred for the given mass of substance can be calculated as follows:
Here, m is mass, c is specific heat capacity and
(c)

Answer to Problem 3E
315 cal.
Explanation of Solution
The specific heat capacity of water is
The calories of energy required to raise the temperature of 9 g of water by 35 oC can be calculated as follows:
Putting the values,
Thus, the amount of energy required is 315 cal.
