What else can I help you with?
Does heat move through air?
Yes, heat can move through air by conduction, convection, and radiation. Conduction is the transfer of heat between molecules in direct contact, convection is the transfer of heat by the movement of air, and radiation is the transfer of heat through electromagnetic waves.
Which type of material allow the transfer of heat by convection?
Fluids like air and water are good conductors of heat by convection. Convection occurs when the fluid moves due to temperature differences, carrying heat energy with it. Solids can also transfer heat by convection if they have enough flexibility for particles to move and transfer energy.
explain how heat transfer can be minimised by convection in a vacuum flask?
Heat transfer by convection can be minimized in a vacuum flask because there is no air (or fluid) inside to carry heat through convection currents. The vacuum creates a barrier that reduces heat transfer by convection, as there is no medium for the heat to move through. This helps to keep the contents of the vacuum flask at their original temperature for a longer period of time.
How do heat moves?
Heat can move through three main processes: conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between materials. Convection is the transfer of heat through the movement of liquids or gases. Radiation is the transfer of heat through electromagnetic waves.
What does Heat transfer by convection requires to transfer heat?
Heat transfer by convection requires a fluid (liquid or gas) to transfer heat. The fluid circulates due to temperature differences, carrying heat from one place to another. Convection is more efficient in fluids compared to solids because molecules in fluids can easily move and transfer heat through their motion.
Does heat move through air?
Yes, heat can move through air by conduction, convection, and radiation. Conduction is the transfer of heat between molecules in direct contact, convection is the transfer of heat by the movement of air, and radiation is the transfer of heat through electromagnetic waves.
Heat convection does not occur in solids because?
Because the atoms do not move around. The whole idea of convection is that 'groups' of things move about. In the case of heat convection these moving groups take or bring their heat with them.
Which method of heat transfer use a medium?
Both conduction and convection require an intervening medium, but convection requires the medium to be able to move.
What direction will heat energy move when placed with a cold object?
convection
Which type of material allow the transfer of heat by convection?
Fluids like air and water are good conductors of heat by convection. Convection occurs when the fluid moves due to temperature differences, carrying heat energy with it. Solids can also transfer heat by convection if they have enough flexibility for particles to move and transfer energy.
What direction do convection currents move?
Convection currents move in a circular motion, where warmer, less dense material rises while cooler, denser material sinks. This creates a continual cycle of rising and sinking currents that transfer heat within a fluid like air or water.
explain how heat transfer can be minimised by convection in a vacuum flask?
Heat transfer by convection can be minimized in a vacuum flask because there is no air (or fluid) inside to carry heat through convection currents. The vacuum creates a barrier that reduces heat transfer by convection, as there is no medium for the heat to move through. This helps to keep the contents of the vacuum flask at their original temperature for a longer period of time.
What direction do convection currents-move?
Convection currents move in upward direction

Convection is more efficient in fluids compared to solids because molecules in fluids can easily move and transfer heat through their motion.
Convection currents move heat more slowly than what?
Convection currents move heat more slowly than conduction, as conduction is the direct transfer of heat through a material without the material itself moving. In contrast, convection involves the transfer of heat through the movement of a fluid, such as air or water, which is generally slower than conduction.
Which substance can heat travel through convection?
In fluids such as liquids and gases, heat can travel through convection. This occurs when particles in the fluid transfer thermal energy as they move from one place to another. Convection is an efficient method of heat transfer in fluids.
