How can the temperature of a gas be raised without supplying any heat to it?
1 Answer
Increase pressure
Explanation:
Gay-Lussacs Law describes a directly proportional relationship between Temperature and pressure.
where k is a constant value - increasing one value would require a proportionally equal increase in the other in order for their quotient to be the same constant value (ie. double one would double the other).
an example of this is when compressed air is released when cleaning your keyboard, the air inside the cylinder is room temperature (at thermal equilibrium with the surroundings). When that air is permitted to leave the cylinder through the nozzle, there is a sharp decrease in pressure (our atmosphere is under less pressure than the contents of the cylinder). This decrease in pressure is why the temperature of the gas also decreases (it's really cold!). The opposite would hold true, putting a gas under pressure would increase its temperature.
