false because it is a solid
There are three types of transferrable energy: conduction, convection, and radiation. Conduction- heat that moves from solid object to solid object by physical means. Convection- heat that moves about a gaseous object (think about boiling water) Radiation- light energy that can travel through space and needs no object to transfer through. The correct answer for this question would be radiation.
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
Because convection occurs by convection currents. Convection currents occur as a result of the movement of a body. Since solids cant move, convection only occurs in fluid, i.e., liquids and gases
Both conduction and convection are types of heat transfer, meaning they move heat from one object to another. The difference is how they transfer the heat. Conduction transfers heat from touching solid to touching solid, while convection transfers heat in fluids (liquid or a gas).Convection transfers heat by having the warm types of fluid rise while the cold sinks. This creates something called a convection current.

convection
Convection currents can occur in either a gas or liquid medium but not in a solid medium (so you can have them in air, and you can have them in magma, but you can't have them in solid rock) and they only occur when there is a temperature difference, so that hotter, less dense material will rise, and colder, denser material will sink.

Conduction is a form of heat transfer. The other forms are radiation and convection. Conduction is the normal way for heat to spread throughout a solid object. Convection is the normal way for gases and liquids.
There are 3 collisions that occur when a vehicle hits a solid object; the initial impact, the passenger impact on restraints or parts of the vehicle, passengers suffering internal collisions with organs

Under conditions of standard temperature and pressure convection is not possible in the solid state of matter.However under extreme conditions (e.g. the high temperature and pressure in the earth's mantle) convection is not only possible in the solid state of matter, but happens all the time just as in the liquid and gas states of matter but much slower.
