40. In thermal energy transfer by convection, when the bottom of a fluid is heated, 1 The molecules in that area gain thermal energy, expand, become less dense and rise. Colder denser fluid then descends to take its place. 2 The fluid in the heated region gains thermal energy, expands, becomes lighter and rises. Colder heavier fluid then descends to take its place. 3 The fluid in the heated region gains thermal energy, expands, becomes less dense and rises. Colder denser fluid then descends to take its place.

Transcribed Image Text:40. In thermal energy transfer by convection, when the
bottom of a fluid is heated,
1 The molecules in that area gain thermal energy,
expand, become less dense and rise. Colder
denser fluid then descends to take its place.
2 The fluid in the heated region gains thermal
energy, expands, becomes lighter and rises.
Colder heavier fluid then descends to take its
place.
3 The fluid in the heated region gains thermal
energy, expands, becomes less dense and rises.
Colder denser fluid then descends to take its
place.
