Question
![**Problem Statement:**
A balloon is heated by adding 35 J of heat while it does 14 J of work on the atmosphere. Calculate the change in internal energy of the system (J).
**Solution Approach:**
To find the change in internal energy (\(\Delta U\)) of the system, we use the first law of thermodynamics:
\[
\Delta U = Q - W
\]
Where:
- \(Q\) is the heat added to the system (35 J).
- \(W\) is the work done by the system on the surroundings (14 J).
**Calculation:**
\[
\Delta U = 35\, \text{J} - 14\, \text{J} = 21\, \text{J}
\]
**Answer:**
The change in internal energy of the system is 21 J.](https://content.bartleby.com/qna-images/question/d0e3b137-93c3-4f8a-ba86-2ec6c73db472/37409ea6-e40a-42f7-b571-9aa20b57f806/8j6mlfq_thumbnail.png)
