Interpretation: The heat change when 45.0 g of water cools from
Concept introduction: To calculate the energy required we use the following relation,
Here, Q = energy required
s = specific heat capacity
m = mass of the sample in grams
Answer to Problem 6STP
B is the correct option.
Explanation of Solution
Given,
specific heat capacity of water
The heat changes from
i.e.,
Now. we calculate the energy required using the following formula.
The heat change when 45.0 g of water cools from
So, option A, C and D are incorrect.
