All substances.
convection
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.
Heat can travel by conduction, convection and radiation in liquids and gases.
No, it travels by convection. Heat rises in the air and then the cool air is drawn in by the heat.
Because conduction and convection require particles to transfer heat. Space is a vacuum (has no particles in it) so convection and conduction cannot occur.
No
Yes it can
convection
You are probably thinking of convection, which is transfer of heat by currents set up by variations in density of the liquid.

Yes, but more travels through liquids by convection.
Heat can transfer through a fluid by conduction and/or convection (with convection being the most efficient). If the fluid is a gas then heat can also transfer through it by radiation (but this does not work in liquid fluids).

Yes heat can travel through gas by way of ignition
Convection is "the transfer of heat through the motion of molecules in a fluid."
