hot coffee in a mug cools over time and the mug warms up. which describes the energy in this system? the average kinetic energy of the particles in the mug decreases. the average kinetic energy of the particles in the coffee increases. thermal energy from the mug is transferred to the coffee. thermal energy from the coffee is transferred to the mug.
Answer
Brief Explanations:
Thermal energy transfers from a hotter to a colder object. Hot coffee is hotter than the mug initially. As the coffee cools and the mug warms, thermal energy moves from the coffee to the mug. The average kinetic energy of coffee particles decreases as it cools and that of mug - particles increases as it warms.
Answer:
Thermal energy from the coffee is transferred to the mug.
