Question

Gases are compressible and have a density that is much higher than liquids and solids. A) True B) False What is the standard temperature used for STP conditions? What is the mole fraction of NO in a 55.0 L gas cylinder at 30 degree C which comes from a mixture of N_2 and NO if you have 3.238 mol of N_2 and the gas cylinder has a total pressure of 2.14 atm? Give five examples of elements that occur as gases at room temperature and pressure? What is the standard pressure used for STP conditions? At a temperature of absolute zero, the volume of an ideal gas is zero. A) True B) False Nitrogen will behave most like an ideal gas A) at high temperature and high pressure. B) at high temperature and low pressure. C) at low temperature and high pressure. D) at low temperature and low pressure. E) at intermediate (moderate) temperature and pressure. Which of the following gases effuses most rapidly? A) nitrogen B) oxygen C) hydrogen chloride D) ammonia E) carbon monoxide ___ is a device used to measure the pressure of gases other to the atmosphere.

Explanation / Answer

17)

Gases are compressible

But density of gas is lower than solid and liquid because same amount of gas occupies a larger volume and this makes gases lesser dense

Answer: False

18)

at STP :

T = 273 K

P = 1 atm

AnsweR: 273 K
