Simple gas laws What is the effect of the following changes on the volume of 1 mol of an ideal gas? (Note: You should NOT need to do any explicit numerical calculations. Use your qualitative understanding of how volume depends on different experimental variables.) The pressure is changed from 2 atm to 760 torr (at constant temperature). (1, 1/2, 1/4,2) Half the gas escapes through a stopcock (at constant temperature and pressure). Answer 2 Both the pressure and the temperature...
A gas sample has an original volume of 600 ml when collected at 720 mm and 35°C. If a change is made in the gas temperature which causes the volume of the gas sample to become 520 ml at 1.00 atm, what is the new temperature?
A sample of argon gas has a volume of 735 mL at a pressure of 1.20 atm and a temperature of 112 ∘C. What is the final volume of the gas, in milliliters, when the pressure and temperature of the gas sample are changed to the following, if the amount of gas does not change? 1) 669 mmHg and 280 K 2) 0.58 atm and 75 ∘C 3) 14.9 atm and -15 ∘C

What is the pressure of the gas in atm when the volume and temperature of the gas sample are changed to 1630 mL and 349 K if the amount of gas is constant? 2.)What is the pressure of the gas in atm when the volume and...
a)Rewrite ideal gas law as volume being a function of pressure and temperature. b) What is the expression for the total derivative dV as a function of pressure and temperature? c) At a pressure of 1.08 atm and 350 K for one mole of ideal gas, what is the predicted change in volume if the pressure changes by 0.10 atm (dp = 0.10 atm) and the temperature changes is 10.0 K?
A cylinder witha movable piston contains an ideal gas. Both the amount of gas and the volume of the container can be adjusted, but the temperature remains constant at 300.0 K. Use the ideal gas law and the individual gas law relationships to answer the questi ons below.

Please help with these two
1. A flask is filled with 1.08 moles of a gas at 20.7 K and
646.8 mm Hg. The flask is then opened and an additional 1.33 moles
are added. The temperature of the flask is then changed to 272.4 K.
What is the pressure (in atm) of the flask under these final
conditions?
2. The density of a gas is 4.22 g/L at a pressure of 1.77 atm
and a temperature of 14.66 °C. What...
