Hello can someone please help me with me 1.The amount space occupied by a gas is called its

kinetic energy
volume
pressure
temperature


2.Which one of the following assumptions of the kinetic molecular theory explains why gases are highly compressible?

Gas particles are in constant, random motion.
No kinetic energy is lost when gas particles collide with each other.
All gases have the same average kinetic energy at a given temperature.
Gas particles are negligibly small compared to the space between them.

3. Which of the following is NOT one of the five basic assumptions of the kinetic molecular theory?

There are attractive and repulsive forces that exist between gas particles.
All gases have the same average kinetic energy at a given temperature.
No kinetic energy is lost during collisions between gas particles.
Gas particles are negligibly small compared to the distances between them.

4. What is the total pressure exerted by a mixture containing hydrogen and nitrogen if the partial pressure of hydrogen is 30.0 kPa and the partial pressure of nitrogen is 40.0 kPa?

40.0 kPa
10.0 kPa
90.0 kPa
70.0 kPa

5. The pressure of 2.0 L of a gas at constant temperature is changed from 380 mmHg to 760 mmHg. The new volume of the gas is…

4.0 L
1.0 L
1.5 L
3.0 L

6. The size of a helium gas filled balloon decreases as the temperature around the balloon is reduced from 22°C to 9°C on a cold winter day. This is due to:

temperature of the gas particles increasing
reduced kinetic energy of the gas particles
particles of gas shrinking in size
flexibility and rigidity of the rubber balloon changes with changing temperature

7. Collisions with the walls of a container by moving particles of a gas are responsible for:

temperature
density
volume
pressure

8. Assume pressure and temperature are constant. As gas is added to a flexible container, the volume inside the container……

Stays the same
Decreases
Increases
Depends on the gas used

10. An 8.25 L sample of oxygen is collected at 25.0 °C and 1.022 atm pressure. What volume will the gas occupy at 0.940 atm and –15.0 °C?

9.27 L
-5.38 L
7.77 L
8.67 L
