3. a sample of argon gas is in a vessel with a movable piston at 37 °c. as the gas is cooled, the volume decreases from 10.0 liters to 4.25 liters. what is the final temperature of the gas?

Answer

# Explanation: ## Step1: Convert initial temperature to Kelvin $T_1=(37 + 273.15)\text{ K}=310.15\text{ K}$ ## Step2: Apply Charles's Law ($\frac{V_1}{T_1}=\frac{V_2}{T_2}$) $T_2=\frac{V_2T_1}{V_1}$ ## Step3: Substitute values $T_2=\frac{4.25\text{ L}\times310.15\text{ K}}{10.0\text{ L}}$ $T_2 = 131.81\text{ K}$ ## Step4: Convert final temperature to Celsius $t_2=(131.81 - 273.15)^{\circ}C=- 141.34^{\circ}C$ # Answer: $-141.34^{\circ}C$
