What else can I help you with?
What can't you get conduction or convection in?
Conduction and convection cannot occur in a vacuum because they both rely on the movement of matter to transfer heat. In a vacuum, there is no medium for heat to be transferred through conduction or convection. Radiation is the primary mode of heat transfer in a vacuum.
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.
Can heat travel by convection through a vacuum?
No. Convection requires a carrier to convey the heat. Vacuum says there is nothing to do the conveying. Radiation does not need a convector, so heat can travel by radiation through a vacuum, like the radiation from the sun.
Is gas or a vacuum a better insulator?
A vacuum is a better insulator than gas because there are no particles in a vacuum to transfer heat through conduction or convection. Gas molecules can transfer heat through conduction and convection, making them less effective as insulators compared to a vacuum.
Explain why conduction and convection cannot take place in an airless vacuum like in outer space?
Conduction and convection require the presence of a medium (such as air or water) for the transfer of heat. In a vacuum, there is no medium to transfer heat, so conduction and convection cannot occur. Heat in a vacuum can only be transferred through radiation.
What cannot happen in a solid or through a vacuum?
convection
Can convection takes place in vacuum?
No

Why is there no heat transfer by convection or conduction through a vacuum?
Conduction needs a conducting medium. Convection needs something to convect. Neither exists in a vacuum.

Which form of heat transfer is reduced by the use of vacuum inside a vacuum flask?
The vacuum reduces both conduction and convection.
Is gas or a vacuum a better insulator?
A vacuum is a better insulator than gas because there are no particles in a vacuum to transfer heat through conduction or convection. Gas molecules can transfer heat through conduction and convection, making them less effective as insulators compared to a vacuum.
Does convection happen in the crust?
No. The crust is rigid; it does not allow convection.
Explain why conduction and convection cannot take place in an airless vacuum like in outer space?
Conduction and convection require the presence of a medium (such as air or water) for the transfer of heat. In a vacuum, there is no medium to transfer heat, so conduction and convection cannot occur. Heat in a vacuum can only be transferred through radiation.
What happen when air travel through vacuum?
The vacuum becomes no longer a vacuum.
