Question

The temperature of a substance is determined by...Select one:a. the number of molecules in a substance.b. the mass of the molecules in a substance.c. the size of the molecules in a substance.d. the average kinetic energy of the molecules in a substance.

Answer 1

Answer:

d. the average kinetic energy of the molecules in a substance.

Step-by-step explanation:

Note that:

• Temperature is the degree of hotness of coldness of an object

,

• It is the measure of the average kinetic energy possessed by the molecules of a substance

,

• The kinetic energy possess by the molecules of a substance increases when the substance is heated

Therefore, with the points highlighted above, the temperature of a substance is determined by the average kinetic energy of the molecules in a substance.
