select the correct answer. the temperature of water in a beaker is 45°c. what does this measurement represent? a. the heat capacity of water b. the total thermal energy of water c. the average kinetic energy of water particles d. the total kinetic energy of water particles
Answer
Brief Explanations:
- Heat capacity is the amount of heat required to change the temperature of a substance, so A is incorrect.
- Total thermal energy depends on mass, temperature, and specific heat capacity, not just temperature, so B is incorrect.
- Temperature is a measure of the average kinetic energy of particles. As temperature increases, average kinetic energy of particles increases.
- Total kinetic energy depends on mass and average kinetic energy (related to temperature), not just temperature, so D is incorrect.
Answer:
C. the average kinetic energy of water particles
