A sample of ideal gas is in a sealed container. The pressure of the gas is 145to

Gay-Lussac’s law states that the pressure of a gas is directly related to its absolute temperature, provided the volume and number of moles of the gas remain the same: (Figure 1)
P1T1=P2T2

A sample of ideal gas is in a sealed container. The pressure of the gas is 145torr , and the temperature is 45∘C . If the temperature changes to 76∘C with no change in volume or amount of gas, what is the new pressure, P2, of the gas inside the container?

Using the same sample of gas (P1 = 145torr , T1 = 45∘C ), we wish to change the pressure to 1450torr with no accompanying change in volume or amount of gas. What temperature T2, in Celsius, is needed to reach this pressure?
