In the study of physics, temperature and heat are often confused with each other. Which of the following statements correctly defines these two element?
A
temperature is a measure of the average kinetic energy of the molecules of a substance
B
heat is a measure of the total kinetic energy of the molecules in a system
C
different materials require different amounts of heat to cause a given change in temperature
D
all of the above
E
A and B only
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Temperature: Measures how hot or cold something is based on the average movement of its particles, while Heat: The energy that moves between objects due to temperature differences. Different materials do require different amounts of heat to cause a given change in temperature, which is related to their specific heat capacities.
