Potential and Kinetic Energy

Question 9 • 2026 Summer 305 CR_2002040-M/J Comprehensive Science 1

Which statements best describe convection? Check all that apply.Convection occurs in solids.Convection occurs in liquids and gases.Convection transfers thermal energy.Convection transfers potential energy.Convection occurs until all of the fluid is at the same temperature.Convection occurs only one time, no matter the temperature.

Answer
A
Convection occurs in solids.
B
Convection occurs in liquids and gases.
C
Convection transfers thermal energy.
D
Convection transfers potential energy.
E
Convection occurs until all of the fluid is at the same temperature.
F
Convection occurs only one time, no matter the temperature.

Explanation

Convection is the transfer of thermal energy through the movement of a fluid, so it occurs in liquids and gases, not solids. Convection currents continue while temperature differences cause parts of the fluid to move and transfer heat; they stop once the fluid reaches the same temperature throughout. Thus, B, C, and E are correct.
