**Question:**

A sample of a gas in a 4 L container at 300 K has a pressure of 1 atm. If the temperature is increased to 600 K and the volume is decreased to 2 L, the pressure is likely to be closest to which of the following?

**Options:**

- A. 0.5 atm
- B. 1 atm
- C. 2 atm
- D. 4 atm (correct answer)

**Explanation:**

Using the ideal gas law and combined gas equation \((P_1 V_1) / T_1 = (P_2 V_2) / T_2\), solve for the final pressure. Initial conditions: \(P_1 = 1\) atm, \(V_1 = 4\) L, \(T_1 = 300\) K. Final conditions: \(V_2 = 2\) L, \(T_2 = 600\) K.

Plug the values into the equation:

\((1 \text{ atm} \times 4 \text{ L}) / 300 \text{ K} = (P_2 \times 2 \text{ L}) / 600 \text{ K}\)

Solving for \(P_2\), the pressure is calculated to be 4 atm.
