Is a vacuum an absence of electricity?
No, a vacuum is an absence of matter.
What is vacuum measured in?
vacuum is measured in pressure. To get a vacuum you need a negative pressure. that would be inches of mercury hg
Vacuum in the doubled-walled vacuum bottle takes care of heat flow by?
no
Does a computer use conduction or convection or radiation?
none
Measuring a final system vacuum is done with the?
system isolated and the vacuum pump turned off.
Can convection takes place in vacuum?
No
Explain why conduction and convection cannot take place in an airless vacuum like in outer space?
they have no energy
Why does convection take place in the atmosphere?
Convection take place because of convection currents
What materials does thermal transfer by convection take place in?
Convection
When does convection take place?
convection takas place wen iron piece is heated
Which layer of the earth does convection take place in?
convection takes place in the outer core......... i think
Can heat transfer take place through Radiation in vacuum?
A vacuum motor can generate heat, which is transferred through radiating patterns, mostly.answer 2 heat can transfer by conduction, radiation, and convection (a special case of conduction).Heat can travel through a vacuum by radiation. I hope the sun felt warm at your place today.
Where in the earth do convection currents occur?
Convection currents take place in the mantle.
Why does convection take place?
Convection takes place because cool air is less dense than warm air.
Heat transfer by radiation is the only method of heat transfer that can travel through a vacuum. What is a vacuum?
A vacuum is a space where there is no, or very little matter (ex. air molecules). One example of a vacuum is outer space. Because there is no matter for heat to travel through via convection or conduction, radiation is the only heat transfer that can take place in a vacuum.
How is heat transfer by radiation different form heat transfer by convection and conduction?
Radiation requires neither contact (through which conduction transfers heat) nor mass flow or movement (through which convection transfers heat). Only radiation can take place in a vacuum. Convection and conduction both require a material medium for the heat transfer to occur. Only radiation can transfer thermal energy through the vacuum of space.
Can transfers of heat by convection take place in liquids?
yes it can.
