- CHARLE'S LAW PROBLEM SOLVING 1.) Under constant pressure condition, a sample of hydrogen gas initially at 85°C and 7.2 L is cooled until its final volume is 4.1 L. What is the final temperature? 2.) Determine the change in volume if 60 ml of gas at 33°C is cooled to 15°C.arrow_forwardPractice problem: A fixed volume of 5 L is holding 4 moles of gas at a pressure of 3 atm. If the quantity of gas is increased to 5 moles, what will be the new pressure? Practice Problem (You first need to determine which law to use). A 0.4 moles of gas with a volume of 2 L has a T of 413 K and a P of 7 atm. If we decrease the T to 325 K while holding the V constant, what is the new P?arrow_forwardPractice Problems 1. A gas has a volume of 350 ml at 30 C. If the volume changes to 400 ml, what is the new temperature? 2. Submarines need to be extremely strong to withstand the extremely high pressure of water pushing down on them. An experimental research submarine with a volume of 1,510 liters has an internal pressure of 1.20atm. If the pressure of the ocean breaks the submarine forming a bubble with a pressure of 253atm pushing on it, how big will that bubble be? 3. A sample of nitrogen inside a rigid, metal container at 20.0ºC is placed inside an oven whose temperature is 50.0 ̊ C. The pressure inside the container at 20.0ºC started at 3.00 atm?arrow_forward
- Problem: A gas cylinder has an internal volume of 2,600L. If the sun heats the gas cylinder from a temperature of 20°C to 55°C. 1. What will be the pressure inside the cylinder? Assume that initial pressure is at standard atmospheric pressure (760 mmHg). 2. How many moles of gas is inside the cylinder in problem 4? (use R=0.08205 L-atm/mol-K)? 3. What gas law should be applied in solving Problem 1?arrow_forwardPROBLEM 2. At what temperature in Kelvin does 5.00g of Air occupy a volume of 50.0 L at a pressure of 1.01 atm?arrow_forwardSolve Using Dalton’s Law of Calculate a Partial Pressure Problem 1. The total pressure exerted by a mixture of O2, N2, and He gases is 1.50 atm. What is the partial pressure, in the atmosphere, of the O2, given that the partial pressures of the N2 and He are 0.75 and 0.33 atm, respectively? Problem 2. A gas mixture contains O2, N2, and Ar at partial pressures of 125, 175, and 225 mm Hg, respectively. If CO2 gas is added to the mixture until the total pressure reaches 623 mm Hg, what is the partial pressure, in millimeters of mercury, of CO2?arrow_forward
- A flask equipped with a valve contains 3.0 mol of H2 gas. You introduce 3.0 mol of Ar gas into the flask via the valve and then seal the flask. a What happens to the pressure of just the H2 gas in the flask after the introduction of the Ar? If it changes, by what factor does it do so? b How do the pressures of the Ar and the H2 in the flask compare? c How does the total pressure in the flask relate to the pressures of the two gases?arrow_forwardBOYLE'S LAW PROBLEM SOLVING 1.) An argon gas occupies 56.2 L at 760 torr. If the volume of gas is decreased to 1/4 of the original volume, calculate its final pressure. 2.) At 0°C and 5 atm, a given sample of gas occupies 75 L. The gas is compressed to a final volume of 30 L at 0°C. What is the final pressure?arrow_forwardEXERCISE 10: A gas occupies a 1.5 liter container of constant volume at 50ºC and 550 mmHg. At what temperature in ° C will the gas reach if the internal pressure is increased to 770 mmHg?arrow_forward
- EXERCISE 1: A quantity of gas occupies a volume of 80 cm3 at a pressure of 750 mm Hg. What volume will it occupy at a pressure of 1.2 atm if the temperature does not change?arrow_forwardEXERCISE 3: A certain amount of gas is at the pressure of 790 mm Hg when the temperature is 25 ° C. Calculate the pressure it will reach if the temperature rises to 200 ° C.arrow_forwardEXERCISE 4: Calculate the new volume, if in a container there is a mass of gas that occupies a volume of 1.3 liters, at a temperature of 280 K.
