Question

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? Explain.

Answer 1

No

Step-by-step explanation:

If you heat the air inside a rigid, sealed container, then you are keeping it's mass and volume constant.

Then, Pressure of the container is directly proportional to the temperature.

Gay-Lussac's Law: This law states that the pressure of a given amount of gas when at constant volume is directly proportional to gas's absolute temperature in Kelvin.

So, if Kelvin temperature doubles, the air pressure in the container will also double.

The relationship between Celsius temperature and Kelvin temperature is not linear.

`T_(K) = T_(C) + 273.15`

If
`T_(K)` becomes
`2*T_(K)`, then
`T_(C)` will become
`(2 * T_(K))- 273.15` .

i.e, it is increasing for sure, but doesn't double.
