Two objects that have different sizes, masses, and temperatures come into close contact with each other.
1) thermal energy is transferred from the larger object to the smaller object.
a. from the object that has more mass to the one that has less mass.
b. from the object that has the higher temperature to the object that has the lower temperature.
c. from the object that has the lower temperature to the object that has the higher temperature.
d. back and forth between the two objects until they come to equilibrium.

b. from the object that has the higher temperature to the object that has the lower temperature.

Explanation:

Thermal energy also known as heat energy.. The thermal energy is transferred from one body to another body due the difference in temperature. The heat travels from the body having greater temperature, to the body having the lower temperature. This process is spontaneous and continues till the bodies come into thermal equilibrium. Hence, the transfer of heat energy depends only upon the temperature difference between the bodies. And it is independent of the size or the mass of the bodies. Thus the correct answer will be:

b. from the object that has the higher temperature to the object that has the lower temperature.
