Gas laws require kelvin
A sealed, rigid container of gas at 27 °C is heated to 327 °C. What happens to the pressure?
Answer A: explanation for every choice
A
Correct. In kelvin, 300 K → 600 K. At constant volume, P/T is constant, so pressure doubles.
B
This uses Celsius temperatures (327/27). Gas laws require kelvin.
C
Pressure rises with temperature at constant volume.
D
Heating increases pressure at constant volume.
TakeawayGas laws use kelvin. At constant volume, P ∝ T.
