Answer

The resulting volume of the gas is 5.41 liters.

Solution

To determine the resulting volume of the neon gas when cooled from \( 30.0^{\circ} \mathrm{C} \) to \( 0.0^{\circ} \mathrm{C} \) at constant pressure, we can use **Charles's Law**: \[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \] Where: - \( V_1 = 6.00 \, \text{L} \) (initial volume) - \( T_1 = 30.0^{\circ} \mathrm{C} = 303.15 \, \text{K} \) (initial temperature in Kelvin) - \( T_2 = 0.0^{\circ} \mathrm{C} = 273.15 \, \text{K} \) (final temperature in Kelvin) - \( V_2 \) is the final volume we need to find. Rearranging the equation to solve for \( V_2 \): \[ V_2 = V_1 \times \frac{T_2}{T_1} = 6.00 \, \text{L} \times \frac{273.15 \, \text{K}}{303.15 \, \text{K}} \] \[ V_2 \approx 6.00 \times 0.901 \approx 5.406 \, \text{L} \] Rounding to the nearest hundredth: \[ V_2 \approx 5.41 \, \text{L} \] **Answer:** 5.41

Beyond the Answer

When cooling gases while keeping the pressure constant, we can use Charles's Law, which states that the volume of a gas is directly proportional to its temperature in Kelvin. First, convert the degrees Celsius to Kelvin: - Initial temperature: \( 30.0^{\circ} C = 303.15 K \) - Final temperature: \( 0.0^{\circ} C = 273.15 K \) Using the formula \( V_1/T_1 = V_2/T_2 \): - \( V_1 = 6.00 L \) - \( T_1 = 303.15 K \) - \( T_2 = 273.15 K \) Rearranging yields: \[ V_2 = V_1 \times \frac{T_2}{T_1} = 6.00 L \times \frac{273.15 K}{303.15 K} \] Calculating this gives: \[ V_2 \approx 5.42 L \] So, the resulting volume of the gas, when rounded to the nearest hundredth, is approximately **5.42 L**.
