The diagram shows two samples of gas enclosed in identical containers. each colored ball represents a gas particle. both samples have the same number of particles.
sample a
mass of each particle: 28 u
average particle speed: 980 m/s
sample b
mass of each particle: 44 u
average particle speed: 1,100 m/s
compare the average kinetic energies of the particles in each sample. which sample has the
higher temperature?
sample a
sample b
neither, both samples are the same.
on

The correct answer is Sample B.

Explanation:

The temperature of a system is directly related to the kinetic energy of the molecules. In the case of gases, as the temperature increases, the kinetic energy increases.

The formula of kinetic energy is:

= 1/2 * m *

: Kinetic energy of each particle.

m: Mass of each particle.

v: Speed of each particle.

For sample A:

= * 28 *

= 13445600

For sample B:

= * 44 *

= 26620000

Being >, we can deduce that sample B has a higher temperature.

Have a nice day!

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
