Question

((((((( A popular physics demonstration uses a "fire syringe" to illustrate how compressing a gas quickly raises its temperature and ignites a piece of paper. Which statement provides an explanation for the demonstration?

The pressure forces oxygen into the paper, igniting it.

Forcing the plunger down through a distance does work on the gas, which increases its thermal energy.

Increasing the pressure slows down the gas molecules, allowing them to get close enough to set the paper on fire.

Since the temperature of the gas is related to its potential energy, the increased pressure increases the potential energy of the gas.
