Heat Transfer
LG3 Violet
Conduction
Radiation
Convection
Heat transfer can be absorbed, reflected, or transmitted through open space
The transfer of heat through a fluid due to of direct contract
The process by which food can be heated by liquids or gases
Examples
When making cupcakes the pan heats up, which transfer the heat to the cupcakes
Examples
Microwave
campfire
Microwaves use radiation as the method of heat transfer
Examples
Hot air balloons
Which is caused by molecular motion
Hot gas or liquid rise, while cooler gas liquid sinks
When the heat from the stove to the pot
It's a thermal radiation
Ice melting
This is because with the ice
Two types of convection
Natural Convection
Forced Convection
A pump
It's a device that moves fluids (liquids or gases) it converted from electrical energy into hydraulic energy
Fan
It blows air past you in hot surroundings and cools you by replacing the air with cooler air
Buoyant forces
Hot fluid rises and cold fluid sinks because density decreases as temperature increases
Sea breeze
Pot of water
The hotter water expands and rises to transfer heat to other parts of the water, while colder water sinks to the bottom
