1.Gay-Lussac's Law A gas container is initially at 47 mm Hg and 77 K (liquid nitrogen temperature.) What will the pressure be when the container warms up to room temperature of 25 ˚C? 2. A container of gas is initially at 0.500 atm and 25 ˚C. What will the pressure be at 125 ˚C? 3.A toy balloon has an internal pressure of 1.05 atm and a volume of 5.0 L. If the temperature where the balloon is released is 200...
A glass container was initially charged with 1.70 moles of a gas sample at 3.75 atm and 21.7 °C. Some of the gas was released as the temperature was increased to 28.1 °C, so the final pressure in the container was reduced to 0.998 atm. How many moles of the gas sample are present at the end?
A gas was initially held at -50.00 °C at a pressure of 25 atm. After heating the gas to 30.00 °C, the pressure decreased to 15 atm, and the volume of gas was found to be 25 L. What was the initial volume of the gas? • Use --273.15 °C for absolute zero. • Report your answer with two significant figures.
1. Consider a gas in a rigid container initially at 533 torr and 15.00 oC. What final temperature, in Kelvin, is needed to reduce the pressure to 342 torr? Use 273.15 for any Kelvin conversion steps. Round your answer to a whole number (ones place) 2. A gas initially at 2.40 atm and 311 K is cooled to 235 K at constant volume. What is the final pressure, in units of atm? Report your answer with two decimal places. A...
A container of gas has a volume of 6.20 L at 2.8 atm. What is the original volume if the pressure was initially 5.6 atm?
If 1.00 mol of argon is placed in a 0.500-L container at 30.0 ∘C , what is the difference between the ideal pressure (as predicted by the ideal gas law) and the real pressure (as predicted by the van der Waals equation)? For argon, a=1.345(L2⋅atm)/mol2 and b=0.03219L/mol.

Part Two: Calculations using the Gas Laws. Describe each relationship in one sentence. 1. A container filled with air at a pressure of 1.02 atm has a volume of 2.75 L. If the volume changes to 3.25 L, what is the new pressure? Describe the relationship between pressure & volume. 2. A sample of gas has a volume of 2.8000 L. When submerged in ice water at T = 0.00 °C (273.15 K), its volume decreases to 2.5700 L. What...
If 1.00 mol of argon is placed in a 0.500-L container at 30.0 ∘C , what is the difference between the ideal pressure (as predicted by the ideal gas law) and the real pressure (as predicted by the van der Waals equation)? For argon, a=1.345(L2⋅atm)/mol2 and b=0.03219L/mol. Express your answer to two significant figures and include the appropriate units.
