Can heat travel by convection through a vacuum where there are no particles?

No, Heat can travel through a vacuum. However it can not travel through a vacuum by convection because there are no particles in a vacuum. convection is the upward movement of particles as they warm up. An example would be hot air moving upwards.


Light can travel through a vacuum as is evidenced when you see the sun or the moon. Can sound travel through a vacuum also?

No, sounds cannot travel through a vacuum. This is because sound requires a medium to travel through because it requires the vibration of particles to travel and there need to be particles to vibrate for it to travel through.
