Why can heat travel through space by radiation but not by conduction or convection?
Heat travels through space by radiation because electromagnetic waves can propagate in a vacuum. In contrast, conduction and convection require a medium like a solid, liquid, or gas to transfer heat through collisions or circulation of particles. Since there is no medium in space, conduction and convection cannot occur.
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.
Why heat cannot reach the earth from the sun by conduction or convection?
Heat from the sun cannot reach the earth through conduction or convection because space is a vacuum and does not contain matter to transfer heat. Heat from the sun reaches the earth through radiation, as electromagnetic waves travel through the vacuum of space.
How does loft insulation stop conduction and convection?
Loft insulation stops conduction and convection as the insulation which is inserted into the wall cavity prevents the particles of heat energy from traveling through the wall cavity, this stops conduction from taking place. Loft insulation also prevents convection as the cavity insulation stops the air particles from moving, therefore they cannot transfer heat and convection cannot take place.
Convection cannot take place in a solid because the particles can only vibrate and not move from one place to another?
That's correct. In solids, particles are closely packed and only vibrate in place due to their fixed positions. This lack of freedom of movement prevents convection, which requires the bulk movement of particles from one place to another.

Why can't the suns heat reach us by conduction or convection?
because there is no medium, conduction and convection need medium to spread through, they cannot spread through vacuum.

Why does heat reaching your body through camp fire is only by radiation and not by conduction and convection?
Normally, people sit beside a fire. The heat reaching our body cannot be heat transfer by convection since this transfers heat vertically due to density changes. Horizontally, heat cannot be transferred by convection. Air is such a poor conductor that it is impossible that the heat transfer is made by conduction. By elimination, we can conclude that the heat transfer in this case is by radiation.
How do you adjust the pressure on a airless paint sprayer?
If there is no air, then you cannot adjust pressure.

That's correct. In solids, particles are closely packed and only vibrate in place due to their fixed positions. This lack of freedom of movement prevents convection, which requires the bulk movement of particles from one place to another.
What type of heat that can only travel in gas and liquid?
This would be convection. Of the three ways that heat can spread from a hot region to a cold region (conduction, convection and radiation), convection is the only one that relies on the flow of high energy (hot) particles. Particles in a solid cannot flow, only those in a liquid or a gas.
Why can't heat travel from the sun by convection or conduction?
Because there are no atoms to collide with to transfer the heat energy from the sun, thus, there is no conduction. This is also the same reason that there are no convection currents in space; There are no atoms to collide with to transfer heat. Thus, the only possible way to transfer heat is by radiation.
How heat conduction and convection can be reduced?
Conduction heat cannot be reduced but covention he can. How? Because as if you have air that is cooler than you the that air absords the heat and takes its place. For more Information just visit Energy.Gov/energysaver/articles/principles-heating-and-cooling.com. Or just type in energy.gov
What are the different types of heat transfer?
There are three types of heat transfer, namely conduction, convection and radiation. Heat is transferred until the reach a state of equilibrium. Conduction is basically the transfer of heat through a surface of contact, such as a fire to the base of a pot. We say that a material is a good or poor conductor of heat when heat travels quickly or slowly in that particular material. Good conductors of heat are metals whereas poor conductors of heat are rubber and Styrofoam. Conduction cannot occur in a vacuum. Convection is the transfer of heat through molecules. It can only occur in liquids and gases as there are relatively big spaces between the molecules. A convection current is where hot air rises and cold air sinks. Convection cannot occur in a vacuum. Radiation is the transfer of heat through a vacuum. Heat is transferred from the Sun to Earth through radiation.
