Answer
Pressure and temperature are directly proportional when moles and volume are kept constant.

Let's start adding math/obscure concepts.
To start out simple:
A 1L flask at 400 K and 1 atm pressure of hydrogen gas is sealed to an identical empty flask so that the hydrogen can be distrubuted throughout both flasks. Then, the flasks are heated such that the temperature of the gas inside is 600K. What is the final pressure of hygrogen inside the flasks?

No replies for a while, so I'll just ask something lol

A 10.00 mL container of water is at 10.0◦C. A 2.23 g piece of zinc at 121 ◦C is dropped into the container. What is the resultant temperature of the system? (cZn=0.384 J/g◦C)
