The main difference between heat and temperature is that temperature is solely dependent on the a. mass of a body. b. velocity of molecules within a body. c. composition of a body. d. state of matter.

velocity of molecules within a body

Explanation:

Temperature is defined as the average kinetic energy of the molecules of a body. The kinetic energy of a body depends on the velocity of the molecules of the body. When the temperature of a body increases, its particles acquire greater kinetic energy and move at higher velocity. Hence temperature depends on the velocity of the molecules of a body while heat is a form of energy.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
