Question

on average, the particles in sample a have ____ kinetic energy than the particles in sample b. this means the temperature of sample a is ____ the temperature of sample b.
which terms best complete the sentences?
a. less; higher than
b. less; lower than
c. more; lower than
d. more; higher than

Explanation:

Temperature is a measure of the average kinetic energy of the particles in a substance. If the particles in sample A have less kinetic energy on average than those in sample B, then the temperature of sample A is lower than that of sample B.

Answer:

B. less; lower than
