The volume of a gas sample is 15 L while the temperature is 50 °C. If the temperature is changed to 30 °C and the pressure remains constant, what will the new volume be? Round your answer to the correct number of significant figures. (Don’t forget to convert the temperature to the Kelvin scale by adding 273 to the Celsius temperature.)
