If the Celsius temperature is doubled at constant pressure, what will happen to the volume?

A) It will double
B) It will remain the same
C) It will decrease by 1/2
D) Additional information is needed

Well it says that the answer is D, but isn't this just Charle's law? Why isn't it A?

Celsius temperature

[opti384]

The basic unit for temperature is K.

The "basic" unit?

A, would be correct for an ideal gas.

Your question does not indicate whether you are dealing with an "ideal gas."

A, would be correct for an ideal gas.

Your question does not indicate whether you are dealing with an "ideal gas."

So if the temp went from 0.0001°C to 0.0002°C you'd expect the volume to double???  Think again.

What would you expect from a temp change from 1°C to 2°C or from 100°C to 200°C or 1000°C to 2000°C???

You need the relative change in temperature in K to work out the answer and as you are not given the start temp you can not work out the answer so D is correct.
