If a 5 m3 of gas initially at STP is placed under a pressure of 3 atm, the temperature of the gas rises to 17◦C. What is the volume now?  Calculate to 2 decimals.

The volume of an automobile tire is 2.5 × 10−2m3 . the pressure of the air in the tire is  3 atm and the temperature is 37C ◦ . what is is the mass of air in grams ? The mean molecular mass of air is 29g.                                     1 atm = 1.01  × 105 Pa ;    Calculate to 2 decimals.

The gas law for an ideal gas at absolute temperature T (in kelvins), pressure P (in atmospheres), and volume V (in liters) is PV = nRT, where n is the number of moles of the gas and R = 0.0821 is the gas constant. Suppose that, at a certain instant, P = 9.0 atm and is increasing at a rate of 0.15 atm/min and V = 13 L and is decreasing at a rate of 0.17 L/min. Find the rate of change of T with respect to time at that instant if n = 10 mol. (Round your answer to four decimal places.) K/min dT_ dt

An ideal gas in a 1.25​-gallon​[gal] container is at a temperature of 135 degrees Celsius ​[°​C] and pressure of 2.4 atmospheres​ [atm]. If the gas is oxygen​ (formula: O2​, molecular weight=32 grams per mole​ [g/mol]), what is the amount of gas in the container in units of grams​ [g]?

The average speed of a gas molecule in meters per second is ????=8????⎯⎯⎯⎯⎯⎯⎯√,vavg=8RTπM, where the temperature ?T is given in kelvins, the molar mass ?M is given in kilogram–moles, and ?=8.31.R=8.31. Calculate ???????dvavgdT at ?=300 KT=300 K for oxygen, which has a molar mass of 0.032 kg/mol.

A bubble of air is rising from the sea floor, from a depth of about 500 m. At this depth the pressure is 5.1*106 Pa (about 50.3 atm) and is at a temperature of about 7.0° C. It rises to the surface with the atmosphere, at a temperature of 20° C. If the bubble is observed to have a volume of 4 cm³ at the surface, what was its volume at the sea floor? Assume the number of moles of gas in the bubble is constant. B.

The gas law for an ideal gas at absolute temperature T (in kelvins), pressure P (in atmospheres), and volume V (in liters) is PV = nRT, where n is the number of moles of the gas and R = 0.0821 is the gas constant. Suppose that, at a certain instant, P = 9.0 atm and is increasing at a rate of 0.15 atm/min and V = 13 L and is decreasing at a rate of 0.17 L/min. Find the rate of change of T with respect to time at that instant if n = 10 mol. (Round your answer to four decimal places.) dT=0.512 dt X K/min

At standard temperature and pressure, a gas has a density of 0.089 kg/m3.  What volume (in m3) does 1.84 kg of hydrogen occupy at standard temperature and pressure [round your final answer to one decimal place]?

An atom of neon has a radius Ne-38. pm and an average speed in the gas phase at 25°C of 350.m/s. Suppose the speed of a neon atom at 25°C has been measured to within 0.10%. Calculate the smallest possible length of box inside of which the atom could be known to be located with certainty. Write your answer as a multiple of "Ne and round it to 2 significant figures. For example, if the smallest box the atom could be in turns out to be 42.0 times the radius of an atom of neon, you would enter "42.Ne" as your answer. [
