Comparing Kelvin and Celsius Temperatures in a Rigid Container

[spaghetti3451]

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?

Correct.
