Maryjane Espinoza · Answer 1

Sample A

Explanation:

Temperature is directly proportional to the average kinetic energy of the particles of a substance. The higher the temperature, the higher the average kinetic energy of the particles is.

Sample A has a temperature of 323 K. Sample B has a temperature of 300 K. Since sample A has a higher temperature then the particles in A have a higher kinetic energy and hence a higher average velocity.
