Car engines are cooled by convection currents in the water pipes. Pums are used to help the water circulate.The water carries the unwanted heat to the radiator, this is how it exchanges the heat. Radiation were gonna learn in a week. Might add the other part next
Know this cus i go Grammar School.

How does heat loss occur?
It can occur through conduction, convection and radiation.
What does intraoperative heat loss occur through?
radiation, convection, conduction, and evaporation
Why can heat travel through space by radiation but not by conduction or convection?
Because conduction and convection require particles to transfer heat. Space is a vacuum (has no particles in it) so convection and conduction cannot occur.
How do you explain the difference between conduction convection or radiation can transfer heat explain?
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.
Radiation is the only type of heat transfer that can occur?
Radiation is the only type of heat transfer that can occur through vacuum (space with no particles).
How is heat transfer by radiation different form heat transfer by convection and conduction?
Radiation requires neither contact (through which conduction transfers heat) nor mass flow or movement (through which convection transfers heat). Only radiation can take place in a vacuum. Convection and conduction both require a material medium for the heat transfer to occur. Only radiation can transfer thermal energy through the vacuum of space.
How is heat transffered through space?
through thermal radiation, a type of electromagnetic radiation, convection and conduction could not occur because there are barely anything in space
What is the only way heat travels through a vacuum?
by radiation - convection and conduction cannot occur in a vacuum!
Where do convection and conduction occur in the atmosphere?
BLA
How convection, conduction and radiation occur in an engine?
In an engine, convection, conduction, and radiation can all play important roles in heat transfer. Convection: Convection is the transfer of heat through the movement of fluids (liquids or gases). In an engine, convection occurs primarily in the cooling system. Coolant fluid circulates through passages in the engine block and cylinder head, absorbing heat from the engine components. As the heated coolant flows away from the engine, it carries the heat with it, and then it is cooled down in the radiator before returning to the engine. This cycle helps to regulate the engine's temperature and prevent overheating. Conduction: Conduction is the transfer of heat through direct contact between materials. In an engine, conduction occurs in various components where there is direct physical contact between hot and cold surfaces. For example, heat is conducted from the combustion chamber to the cylinder walls and then to the engine block. Similarly, heat is conducted from the cylinder head to the engine block and to the cooling system components. Good thermal conductivity of materials used in engine construction helps to efficiently transfer heat away from critical components. Radiation: Radiation is the transfer of heat through electromagnetic waves. In an engine, radiation occurs as heat is emitted from hot surfaces in the form of infrared radiation. This radiation can be absorbed by cooler surfaces within the engine compartment or can escape into the surroundings. However, radiation is generally a less significant mode of heat transfer in engines compared to convection and conduction. Overall, a combination of these three mechanisms helps to manage the heat generated by combustion and friction within the engine, ensuring that it operates within safe temperature limits and remains efficient.
When you turn on a heater how does the warmth get to you?
All three methods of heat transfer occur: conduction, convection, radiation. However, heaters are often designed to transfer lots of heat via radiation.
What is more likely to occur in the water thermal energy transfer by conduction or convection?
Convection
