The correct Answer is:
To solve the problem of how much work is done in decreasing the volume of an ideal gas, we can use the formula for work done in a thermodynamic process at constant pressure. The formula is: \[ W = P \Delta V \] Where: - \( W \) is the work done, - \( P \) is the pressure, - \( \Delta V \) is the change in volume. ### Step-by-Step Solution: **Step 1: Identify the given values.** - Pressure, \( P = 1 \times 10^5 \, \text{N/m}^2 \) - Change in volume, \( \Delta V = 2.4 \times 10^{-4} \, \text{m}^3 \) **Step 2: Substitute the values into the work formula.** Using the formula \( W = P \Delta V \): \[ W = (1 \times 10^5 \, \text{N/m}^2) \times (2.4 \times 10^{-4} \, \text{m}^3) \] **Step 3: Perform the multiplication.** Calculating the work done: \[ W = 1 \times 10^5 \times 2.4 \times 10^{-4} \] To simplify this, we can multiply the coefficients and add the exponents: \[ W = 2.4 \times 10^{5 - 4} = 2.4 \times 10^1 \] **Step 4: Calculate the final value.** Now, calculate \( 2.4 \times 10^1 \): \[ W = 2.4 \times 10^1 = 24 \, \text{Joules} \] ### Final Answer: The work done in decreasing the volume of the ideal gas is **24 Joules**. ---
