Question

1. An ideal gas in a sealed container has an initial volume of 2.65 L. At constant pressure, it is cooled to 21.00
degrees Celsius where its final volume is 1.75L. What was the initial temperature?
2. In a nitrogen gas has occupied a volume of 500ml at a pressure of 0.971atm. What volume will the gas fill at a
pressure of 1.50 atm, assuming the temperature remains constant?
3. When a supply of hydrogen gas is held in a 4-liter container at 470C it exerts a pressure of 800 torrs. The supply
is moved to a 2-liter container, and cooled to 450C. What is the new pressure of the confined gas? PLZZZZZZZZZZZZ ANSWER IF POSSIBLE WITH STEPS I NEED TO KNOW U ARRIVED AT THE ANSWERS TO UNDERSTAND VERY WELL .THANK YOU

Answer 2

Answer:

1. An ideal gas in a sealed container has an initial volume of 2.55 L. At constant pressure, it is cooled to 25.00 degrees Celcius, where its final volume is 1.75 L.

2. The answer is 324mL . which states that

a gas' pressure and volume are proportional to eachother. It can be derived from the combined gas law, PV=nRT , by keeping T constant.

3. I am not sure about 3rd question
