No

Question 3

Answer 3

Only solids

Question 4

What happens to the particles in conduction

Question 5

Does convection involve particles

Answer 5

Yes

Question 6

Does convection occur in a vacuum

Answer 6

No

Question 7

What does convection occur in

Answer 7

Only liquids and gases

Question 8

What happens to the particles in convection

Answer 8

When a fluid is heated the particles move faster and spread out from eachother. Thid makes the warm fluid less demse. The less dense fluid rises where as because the cooler fluid is more dense it sinks. The cooler fluid then heats up and rises. This created a circular motion called a convection current.
