**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.

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.
