Convection occurs only in?
- Liquids and gases
- Solids and gases
- Liquids and solids
- All states of matter
Explanation
Convection is the transfer of heat through the movement of a fluid, and only liquids and gases can flow freely, allowing for the movement of heat currents.
Additional information:
Solids and gases:
While solids can transfer heat through conduction, they cannot convect because their particles are fixed in place and cannot move freely.
Liquids and solids:
Convection only occurs in liquids and gases. Solids do not convect due to their fixed particle structure.
All states of matter:
Convection is specifically related to the movement of fluids, which excludes solids.
