The Temperature T of a Gas Sample Varies Jointly as the Pressure

Multiple Choice

The temperature T of a gas sample varies jointly as the pressure P and the volume V. If the temperature is 297 kelvin when the volume is 4.6 liters and the pressure is 1.2 atmospheres, then what is its temperature if the gas is compressed to 1.5 liters at 2.9 atmospheres? Round your answer to the nearest tenth of a kelvin. [The unit "kelvin" is simply a temperature unit related to the Celsius degree. The exact relationship between the two plays no part in the solution of this problem.]

A) 230.8 kelvin
B) 234.0 kelvin
C) 198.9 kelvin
D) 242.9 kelvin
