How is convection related to the rise and fall of wax in lava lamps?
The heat source typically heats up to high temperatures and this means solid wax lava lamps must melt first.
What happens for heat to be transferred by convection?
the liquid or gas must circulate to move the heat.
What is the difference between radiant heat and convection heat?
In convection heat you heat the air first and then use the hot air to heat yourself. In radiant heat, the energy must be radiated directly from the heat element to your body. Note that radiant is much more directional.
Before the water in the pot can heat up the pot itslef must heat up does the pot heat up by conduction convection or radiation?
Conduction.
Is body heat convection heat?
Yep, the heat is transferred via convection when fluid flow is involved, which is primarily blood flow. For example, you hands are cold, then warm blood flow helps to warm them up. That's convection. Sure conduction is also involved. When heat must pass solid barrier such as cell walls then the heat is transferred via conduction.

Can heat travel by convection through a vacuum?
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.
What must happen to cause water to evaporate?
Heat.
If you are in space what way does heat travel?
The three ways that heat travels are conduction, convection and radiation. In space there is no matter between things so conduction and convection are not possible. But radiation does not need to travel trough matter so it can go through empty space. All of the light and heat from the Sun travels as radiation to the Earth.
What has to happen for metamorphism occur?
Heat and high pressure
Why transfer of heat in fluids take place by convection?
Heat transfer will use all three modes, but convection is (by far) the fastest, thus you can ignore the other two if you wish. This will produce errors in your calculations - you must decide if the errors are small enough to be acceptable.
Why heat can travel through space only by radiation?
there is no medium for conduction or convection. all energy must be received from radiative sources.
