Final answer:
Temperature is an indirect measurement of heat energy in a substance, representing the average kinetic energy of particles, and differs from heat, which is the transfer of energy between objects.
Step-by-step explanation:
The correct statement about temperature is: a. Temperature is an indirect measurement of the heat energy in a substance. This means that temperature is a measure of how hot or cold an object is relative to another object, which indirectly reflects the thermal energy content. However, temperature is not the same thing as heat or energy. Heat is the transfer of thermal energy between objects of different temperatures, and temperature is a measure of the average kinetic energy of the particles within a substance. For instance, an increase in temperature might cause a substance to change from solid to liquid.
