- A sample of nitrogen gas was transferred to a 100 mL container at 100 kPa and 75.0 C. What was the original temperature of the gas if it occupied 125 mL and exerted a pressure of 125 kPa?
- What happens when a given amount of gas at a constant temperature increases in volume?
- A container with a volume of #18 L# contains a gas with a temperature of #150^o K#. If the temperature of the gas changes to #120 ^o K# without any change in pressure, what must the container's new volume be?
- If #7/6 L# of a gas at room temperature exerts a pressure of #2 kPa# on its container, what pressure will the gas exert if the container's volume changes to #5/4 L#?
- If #7/5 L# of a gas at room temperature exerts a pressure of #6 kPa# on its container, what pressure will the gas exert if the container's volume changes to #2/3 L#?
- A container with a volume of #19 L# contains a gas with a temperature of #460^o C#. If the temperature of the gas changes to #320 ^o K# without any change in pressure, what must the container's new volume be?
- A container has a volume of #9 L# and holds #5 mol# of gas. If the container is compressed such that its new volume is #12 L#, how many moles of gas must be released to maintain a constant temperature and pressure?
- A 73.8 g sample of O2 gas at 0.0 oC and 5.065x10^4 Pa is compressed and heated until the volume is 3.26 L and the temperature is 27 oC. What is the final pressure in Pa? T= 273K and 300K i think u have to convert L to m^3?
- The gas inside of a container exerts #32 Pa# of pressure and is at a temperature of #50 ^o K#. If the temperature of the gas changes to #90 ^oK# with no change in the container's volume, what is the new pressure of the gas?
- A container with a volume of #18 L# contains a gas with a temperature of #270^o C#. If the temperature of the gas changes to #350 ^o K# without any change in pressure, what must the container's new volume be?
- What is the number of moles of gas in 20.0 L of oxygen at STP?
- The gas inside of a container exerts #9 Pa# of pressure and is at a temperature of #690 ^o K#. If the temperature of the gas changes to #210 ^oC# with no change in the container's volume, what is the new pressure of the gas?
- The gas inside of a container exerts #18 Pa# of pressure and is at a temperature of #360 ^o K#. If the pressure in the container changes to #24 Pa# with no change in the container's volume, what is the new temperature of the gas?
- What are some common mistakes students make with the Boyle's law?
- If #18 L# of a gas at room temperature exerts a pressure of #35 kPa# on its container, what pressure will the gas exert if the container's volume changes to #14 L#?
- A canister containing air has a volume of #85# #cm^3# and a pressure of #1.45# #atm# when the temperature is #310# #K#. What is the pressure when the volume is increased to #180# #cm^3# and the temperature is reduced to #280# #K#?
- If #3/7 L# of a gas at room temperature exerts a pressure of #9 kPa# on its container, what pressure will the gas exert if the container's volume changes to #5/9 L#?
- If #18 L# of a gas at room temperature exerts a pressure of #5 kPa# on its container, what pressure will the gas exert if the container's volume changes to #12 L#?
- Why does the pressure increase inside a car tire after it is driven for a while?
- A container with a volume of #7 L# contains a gas with a temperature of #120^o K#. If the temperature of the gas changes to #360 ^o K# without any change in pressure, what must the container's new volume be?
