1. The problem statement, all variables and given/known data The temperature of an ideal gas is doubled while the volume is kept constant... Does the absolute pressure of the gas double when the temperature that doubles is A) the Kelvin temperature and B) the Celsius temperature. Explain? 3. The attempt at a solution I can't put the solution to this in words, but I think I might have the right idea... not sure. 1 degree celsius = 274 Kelvin, and if we were to double the celsius temperature we'd have the following: 2 degrees celsius = 275 Kelvin. So while the celsius temperature doubles the absolute pressure of the gas doubles as well, but if Kelvin were to double then the absolute pressure of the gas wouldn't double but increase exponentially...?
