An alcohol thermometer makes use of alcohol's changing in order to measure temperature. as the temperature goes up, the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same
