conduction and convection

Question 1

know the difference between the two (conduction and convection)

Answer 1

CONDUCTION is the transfer of thermal energy through a substance, or between substances in contact, by the collision of particles.

CONVECTION is the transfer of thermal energy from one part of a fluid to another by a circulating current of faster moving and slower moving particles.

Question 2

how is thermal energy transferred (conduction)

Answer 2

CONDUCTION when you cook an egg sunny side up in a pan on a hot stove, the thermal energy transfers from the hot stove burner and through the pan. the energy then moves from the pan and into the cold egg.

Question 3

how is thermal energy transferred (convection)

Answer 3

CONVECTION when soup is heated, the water particles near the bottom of the pot start to move faster and farther apart. this makes the particles near the bottom less dense and lighter than those near the top.
the less dense soup moves to top of pot to replace cold soup. read pg.210
