Which statement describes the particles of an ideal gas based on kinetic molecular theory?

which particle diagram represents a sample of oxygen gas at STP

c

a sample of gas is held at constant pressure. increasing the kelvin temperature of this gas causes the average kinetic energy of its molecules to (1 point)

increase and the volume of the gas sample to increase

as the temperature of a gas increases with the volume remaining constant, the pressure of the gas

increases

when a sample of gas is cooled in a sealed, rigid container, the pressure the gas exerts on the walls of the container will decrease because the gas particles hit the walls of the container

less often and with less force

a real gas behaves least like an ideal gas under conditions of (1 point

low temperature and high pressure

Each stoppered flask shown contains two liters of gas at STP. Each gas sample has the same

number of molecules

which phrase describes the motion and attractive forces of idea has particles? (1 point)

random straight-line motion and no attractive forces

the data table provided shows data for the temperature, pressure and volume of four samples. which two samples of gas contain the same number of molecules

II and IV

a cylinder with a tightly fitted piston is shown in the diagram. as the piston moves downward, the number of molecules of air in the cylinder (1 point)

remains the same

a real gas differs from an ideal gas because the molecules of a real gas have

some volume and some attraction for each other

which set of values represents standard temperature and pressure (STP)

101.3 kPa and 0 degrees C

if 2.0 moles of CO2 (g) are placed in a 2700 mL container at a temperature of 25 degrees Celsius, what is the pressure exerted by the gas? (R = 0.08206 Latm/molK (3 points)

18 atm

a 220.0 mL sample of helium gas is in a cylinder with a movable piston at 105 kPa and 275K. the piston is pushed in until the sample has a volume of 95.0 mL. the new temperature of the gas is 310. K. what is the new pressure of the sample? (2 points)

274 kPa

a rigid cylinder with a movable piston contains a sample of hydrogen gas. At 330. K, this sample has a pressure of 150. kPa and a volume of 3.50 L. what is the volume of this sample at STP (2 points)

4.29

at which temperature and pressure will a sample of neon gas behave most like an ideal gas?

500. K and 2.0 atm

7. which graph shows the relationship between pressure and Kelvin temperature for an ideal gas at constant volume?

A linear

which graph represents the relationship between pressure and volume for a sample of an ideal has at constant temperature? (1 point)

C

in which 1.0 gram sample are the particles arranged in a crystal structure?

CaCl2 (s)

under the same conditions of temperature and pressure, which of the following gases would behave most like an ideal gas? (1 point)

He

which temperature change would cause a sample of an ideal gas to double in volume while the pressure is held constant?

from 200. degrees K to 400. degrees K

Which statement describes the particles of an ideal gas based on kinetic molecular theory?

the volume of the particles is considered negligible.
