The correct Answer is:
To solve the problem, we will use the Ideal Gas Law, which states that for a given amount of gas, the relationship between pressure, volume, and temperature is given by the equation: \[ P_1 V_1 / T_1 = P_2 V_2 / T_2 \] Where: - \( P_1 \) = initial pressure - \( V_1 \) = initial volume - \( T_1 \) = initial temperature (in Kelvin) - \( P_2 \) = final pressure - \( V_2 \) = final volume (what we need to find) - \( T_2 \) = final temperature (in Kelvin) ### Step 1: Convert temperatures from Celsius to Kelvin 1. **Initial Temperature (T1)**: \[ T_1 = 27^\circ C + 273 = 300 \, K \] 2. **Final Temperature (T2)**: \[ T_2 = 177^\circ C + 273 = 450 \, K \] ### Step 2: Identify the given values - Initial volume \( V_1 = V \) liters - Initial pressure \( P_1 = 1 \, \text{bar} \) - Final pressure \( P_2 = 1.5 \, \text{bar} \) - Initial temperature \( T_1 = 300 \, K \) - Final temperature \( T_2 = 450 \, K \) ### Step 3: Rearrange the Ideal Gas Law to solve for \( V_2 \) Using the Ideal Gas Law: \[ \frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2} \] Rearranging gives: \[ V_2 = \frac{P_1 V_1 T_2}{P_2 T_1} \] ### Step 4: Substitute the known values into the equation Substituting the known values into the equation: \[ V_2 = \frac{(1 \, \text{bar}) \cdot (V \, \text{liters}) \cdot (450 \, K)}{(1.5 \, \text{bar}) \cdot (300 \, K)} \] ### Step 5: Simplify the expression \[ V_2 = \frac{1 \cdot V \cdot 450}{1.5 \cdot 300} \] \[ V_2 = \frac{450V}{450} = \frac{V}{1.5} \] \[ V_2 = \frac{2}{3} V \] ### Final Answer: The volume \( V_2 \) at \( 177^\circ C \) and \( 1.5 \, \text{bar} \) will be \( \frac{2}{3} V \) liters. ---
