Question 1 (1 point) If PV = nRT, then if I increase the amount of moles of a gas in a glass jar,
and the temperature of the gas stays the same,
and volume of a jar obviously stays the same,
what will happen to pressure inside the jar?

The pressure also increases.

Explanation:

As we can see in this equation,

Pressure is directly proportional to the moles of a gas in the glass jar.

Temperature and Volume remains constant.

Hence, if number of moles of a gas increases, the pressure also increase "n" number of times.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

the answer is 303.15 or 303
