9. An unknown gas has a volume of 200L at 5 atm and -140°C. What is its volume at STP? 10. A Los Angeles class nuclear sub has an internal volume of eleven million liter at a
pressure of 1.250 atm. If a crewman were to open one of the hatches to the outside
ocean while it was underwater (pressure of 15.75 atm), what would be the new volume
of the air inside?
11. A man heats a balloon in the oven (Why?who knows?...it is a crazy world we live in).
If the balloon initially has a volume of 0.40 L and a temperature of 20 °C, what is its
volume after he heats it to 250 °C?
Mixed Gas Laws
12. A gas has a pressure of 1.26 atm and occupies a volume of 7.40 L. If the gas is
compressed to a volume of 2.93 L, what is its new pressure?
13. People who are angry sometimes say that they feel as if they'll explode. If a calm
person with a lung capacity of 3.5 liters and a body temperature of 36 °C gets angry,
what is the volume of their lungs if their temperature rises to 39 °C. Do you think they
will really explode?

If the particles in a sample of matter have an orderly arrangement and move only in place, the sample is a

Problem #3 (ch. 1, problem 15)the ideal gas law provides one way to estimate the pressure exerted by a gas on a container. the law isí‘ťí‘ť=푛푛푛푛푛푛푉푉more accurate estimates can be made with the van der waals equationí‘ťí‘ť=푛푛푛푛푛푛푉푉â’푛푛푟푟â’푞푞푛푛2푉푉2where the term nb is a correction for the volume of the molecules and the term an2/v2is a correction for molecular attractions. the values of a and b depend on the type of gas. the gas constant is r, the absolutetemperature is t, the gas volume is v, and the number of moles of gas molecules is indicated by n. if n = 1 mol of an ideal gas were confined to a volume of v = 22.41 l at a temperature of 0â°c (273.2k), it would exert a pressure of 1 atm. in these units, r = 0.0826.for chlorine gas (cl2), a = 6.49 and b = 0.0562. compare the pressure estimates given by the ideal gas law and the van der waals equation for 1 mol of cl2 in 22.41 l at 273.2 k. what is the main cause of the difference in the two pressure estimates, the molecular volume or the molecular attractions?

If you add 10ml of hot water to 10ml of cold water and the change in tempature 8°c calculate how much energy is gained by the cold water
