Heat flow occurs when two systems in contact are not at the same temperature.
What is heat flow?
- when two bodies of different temperatures are in contact, heat flow takes place.
- Heat flows till the two bodies in contact achieve equilibrium.
- To achieve equilibrium, heat flows from hotter bodies to colder bodies.
- There is no heat flow after achieving the state of equilibrium because the amount of heat flow from one body to the other is the same.

the emission of electrons or other free carriers when light shines on a material.
Answer:
This is because the age of the universe is determined by the pace of expansion in the past, and each model forecasts a different pace.
Explanation:
The age of the universe is determined by the pace of expansion in the past, and each model forecasts a different pace.
This is due to the fact that the expansion rate in the coasting model is constant and never changes. Because the cosmos is growing faster now than during the old days, recollapsing and critical models give shorter ages. According to the accelerating model, the universe is growing at a slower rate currently than in the past, implying an older age.
