`200J` of work is done to compress an ideal gas isothermally. How much heat flows from the gas during the compression process?

Explanation

To solve the problem of how much heat flows from an ideal gas during isothermal compression, we can follow these steps:

### Step 1: Understand the Process
In an isothermal process, the temperature of the gas remains constant. For an ideal gas, this means that any work done on the gas will result in an equivalent amount of heat being released or absorbed.

### Step 2: Apply the First Law of Thermodynamics
The first law of thermodynamics states that:
\[ \Delta U = Q - W \]
