Answer:
The amount of heat gained by the water in cup 2 after adding the hot object(s) to it is 2119.121 Joules
Explanation:
As we know
Amount of heat gained
Q = mc (T2-T1)
Here,
mass of water in cup 2 (m) = 79.10 grams
Temperature of water in cup 2 = 16.8 degree Celsius
Specific heat of water (c) = 4.186 J/(g °C)
Final Temperature of water in cup 2 = 23.2 degree Celsius
Substituting the given values, we get -
Q = 79.10 * 4.186 * (23.2 -16.8) = 2119.121 Joules
The amount of heat gained by the water in cup 2 after adding the hot object(s) to it is 2119.121 Joules
