How is heat transferred through liquids and solids?
By means of the atomic vibrations about their mean position.
What is the transfer of heat by the movement of particles in the fluids called?
I expect that you mean convection.
What do conduction convection and radiation mean?
conduction is the transfer of heat between two surfaces in contact with each other convection is the transfer of heat into a moving fluid radiation is the transfer of heat via electromagnetic waves
What does it mean for heat to be transferred by radiation?
Energy is transferred when molecules absorb electromagnetic waves.
Is heat only transferred if there is no temperature change?
I am not quite sure what you mean. If heat is exchanged, there is usually a temperature change.
How is heat transferred through a radiator?
Convection, which is the transfer of heat by thermal currents in the air (or other medium)
What does it mean for heat to be transferred by convection?
Energy is transferred through moving currents of warmer air or liquid.
How is heat transferred through liquids and solids?
By means of the atomic vibrations about their mean position.
What does 'energy transferred' mean?
Energy can be transferred from one location to another as in the sun's energy travels through space to Earth. The two ways that energy can be transferred are by doing work and heat transfer. Also energy can be transferred from one object to another.
How heat transfered by convection?
Convection is the process by which heat is transferred by a "fluid" (which, in this case, can actually mean a liquid or a moving gas - both are considered "fluids"). Heat is always transferred from an area of high heat to an area of low heat, regardless of the method. When your hand touches a hot stove, heat moves from the stove to your hand to try to "even out" the amount of heat between the two objects. In convection, heat is first transferred from an area of high heat to the fluid, then from the fluid to an area of (relatively) lower heat. Imagine you're sitting downwind of a bonfire. The wood has lots of heat - some of it is transferred to the air. The air is pushed toward you by wind, and when the air hits your skin, there is another heat transfer because your skin has less heat than the air. The net result is a transfer of heat from the wood to your skin, and we say this is by convection. Another example might be the way everything in a small kitchen gets warm in a hurry when things are baking in a hot oven. Some radiation occurs, but lots of air picks up heat from the stove, and then rises to be displaced by cooler air. The hot air heats things in the upper regions of the kitchen, and then cools and sinks. It then may return to the stove to pick up more heat as hot air there continues to circulate upward. Convection currents in air transfer heat.
How are conduction and convection similar?
they are two modes of heat transfer and both mean heat transfer involving materials
How does your body lose heat through convection?

How many kind of heat is there?
Think you mean types of heat transfer? Radiation, Convection, and Conduction.
What does convection mean in science terms?
convection is the transfer of heat in a liquid or gas by thermal energy from one part of a fluid to another. ;0)
Why are there convention current s in the mantle?
Convention? You mean convection! The mantle is not solid but molten, although extremely viscous, and heated by radio-active decay. Since the only escape for the heat is conduction through the crust and in lava, the consequent temperature gradients create convection currents.
Is it true that convection is the flow of heat energy by direct contact?
Convection needs a fluid. More specifically, convection is the motion of a fluid that is caused by the effects of non-uniform density. In all real examples of convection, the non-uniform density is caused by non-uniform temperature. If you accept the relationship between temperature and density as a given physical law, then you do not need to talk about molecules in order to explain convection; but if you want also to explain why the density changes with temperature, then you probably will need to talk about the molecular nature of the fluid.

I expect that you mean convection.
