SUMMARY

Heating the air inside a rigid, sealed container until its Kelvin temperature doubles results in a doubling of the air pressure. However, doubling the Celsius temperature does not yield the same outcome. This is due to the direct proportionality of pressure to Kelvin temperature, while pressure is proportional to the sum of 273 and the Celsius temperature. The distinction between these temperature scales is crucial for understanding gas laws.

If you heat the air inside a rigid, sealed container until its Kelvin temperature doubles, the air pressure in the container will also double. Is the same thing true if you double the Celsius temperature of the air in the container?

I don't think so, because pressure is directly proportional to the Kelvin temperature and pressure is directly proportional to (273 + the Celsius temperature).
What do you think?
