Convection and conduction are both means of heat transfer involving materials.
Convection usually occurs in liquids and gases. Heated parts of these materials expand and become less dense. Pressure from the cooler, less light parts (due to gravity) pushes the lighter heated parts upwards. Near the surface , these cool, sink and circulate upwards again when heated.
Conduction can occur in all substances but most efficiently in solids like metals where the particles are close together. If the particles in one part vibrate more when heated to a higher temperature, this vibration is passed along through the material. Conduction can occur in any direction but always from the hottest towards the coolest parts.
What else can I help you with?
Compare and contrast conduction and convection?
Conduction is the transfer of heat through direct contact between materials, while convection is the transfer of heat through the movement of a fluid (liquid or gas). Conduction occurs in solids and liquids, while convection occurs in fluids. In conduction, heat transfer is slower but can happen in any state of matter, while in convection, heat transfer is faster but is limited to fluids.
What are the three forms of heat transfer?
The three forms of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles, convection is the transfer of heat through the movement of fluids or gases, and radiation is the transfer of heat through electromagnetic waves.
Is conduction or convection faster when transferring heat?
Convection is generally faster than conduction when transferring heat.
What are 3 types of energy heat transfers?
The three types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through a material, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.

What is the differ of conduction and convection?
conduction by itself is slower to heat but conduction and convection is faster to heat
What are the differences of conduction and convection?
Convection has a cycle of what happens. Conduction dosent have a cycle
What makes convection and conduction possible?
Lack of a flow medium will inhibit conduction and convection.

What occurs in mercury of a thermometer convection or conduction?
convection
Is conduction or convection faster when transferring heat?
Convection is generally faster than conduction when transferring heat.
Does convection or conduction travel at the speed of light?
No. The speeds of convection and conduction vary, but they are nowhere near the speed of light.
