Question

Which of the following statements are true?

a. The temperature of a gas sample is independent of the average kinetic energy.
b. There are gas molecules that move faster than the average.
c. All the gas molecules in a sample cannot have the same kinetic energy.
d. The average kinetic energy of gas molecules increases with increasing temperature.
e. The average speed of gas molecules decreases with decreasing temperature.

Answer 1

b,c,d,e

Step-by-step explanation:

Temperature and speed/KE are directly proportional.

Some molecules do move faster than average. Because of this, not all gas particles will have the same KE.

Answer 2

b, c,d

Step-by-step explanation:

b. There are gas molecules that move faster than the average.

c. All the gas molecules in a sample cannot have the same kinetic energy.

d. The average kinetic energy of gas molecules increase with increasing temperature.
