Concept explainers
To identify: Whether internal energy of ice berg and a cup of hot coffee is more.
Answer to Problem 33A
The internal energy of ice berg is more than a cup of coffee.
Explanation of Solution
Introduction:
Internal energy: Energy of close system rise by interaction of particles.
Internal energy of any substance depends on the molecule of substance or volume. So, if the volume is more then internal energy is also more. Since the volume of ice berg is greater than the volume of a cup of coffee, so ice berg will have more internal energy in comparison to a cup of coffee.
Conclusion:
Therefore, internal energy of ice berg is more than a cup of coffee.
