the liquid or gas must circulate to move the heat.

What conditions are necessary for the transfer of heat from one body to another?
For the transfer of heat to occur, there must be a temperature difference between the two bodies. Additionally, there should be a medium through which heat can be transferred, such as conduction, convection, or radiation. Lastly, the bodies must be in contact or have a means of exchanging energy for heat transfer to happen.
What must happen for the heat to be transferred by convection?
For heat to be transferred by convection, it requires the movement of a fluid (liquid or gas) caused by temperature differences. As the fluid near a heat source becomes warmer, it becomes less dense and rises, displacing cooler fluid that then moves to take its place. This process creates a circulating flow of fluid that transfers heat throughout the medium.
What is the condition for transfer of heat in convection?
Convection is the transfer of heat through the movement of a fluid (liquid or gas). The condition for convection to occur is that the fluid must be in motion, either naturally (natural convection) due to density differences or externally induced (forced convection) by a fan or pump. Heat transfer in convection is more efficient than conduction as it involves both thermal energy transfer and physical movement of the fluid.
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.
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.

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.
What must happen for heat to be transferred by convention?
Heat transfer by convection occurs when a fluid or gas moves due to temperature differences, carrying heat with it. As the fluid or gas near a heat source becomes warmer, it expands and becomes less dense, causing it to rise and displace cooler, denser fluid. This movement transfers heat from the warmer area to the cooler area.
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.
If you are roasting a large quantity of ducklings and must use both of your conventional ovens at the same temperature but find the ducklings in the convection oven are done first. Why did this happen?
The ducklings in the convection oven cooked faster because convection ovens circulate hot air, promoting even and efficient heat distribution around the food. This airflow can lead to quicker cooking times compared to conventional ovens, which rely on radiant heat from the top and bottom elements. As a result, the ducklings in the convection oven reached the desired internal temperature sooner than those in the conventional oven.
Can you pump down a heat pump system in heat mode just as you would do in the cool mode?
No, the energy in a heat pump system must be transfered to another heat pump system because the first law of thermodynamics say that energy cannot be created nor destroyed
What condition must exist for transfer of heat to occur?
There must be a temperature difference between two bodies or regions, with heat naturally flowing from the higher temperature to the lower temperature. Additionally, there must be a medium, such as air, water, or a solid material, through which the heat can be transferred via conduction, convection, or radiation.
