Is convection the transfer of heat energy through the currents of fluids? True or False
True
What is conduction?
The transfer of heat energy through direct contact
Define Conduction:
Conduction refers to the transfer of energy through the movement of particles that are in contact with each other.Heat conduction (or thermal conduction) is the transfer of energy from a warmer substance to a colder one through direct contact, such as someone touching the handle of a hot metal skillet.
Define Radiation
The energy radiated or transmitted in the form of rays, waves, or particles. A stream of particles or electromagnetic waves that is emitted by the atoms and molecules of a radioactive substance as a result of nuclear decay. Radiotherapy. The radial arrangement of anatomical or histological parts.
What type of enegry transfer would be used if you cooked a hot dog by boiling?
A. Radiation B. Convection C. Conduction
B. convection
What is density?
Causes fluids to rise and fall.
What is an insulator
Something that dosn't transfer heat well.
Give one example of Conduction
Give one example of Radiation:
Getting a sunburn is absorbing to much heat energy through _____? A. Radiation B. Convection C. Conduction
A.radiation
Name three examples of convection?
Why does your desk feel warmer than the metal pole on your chair, even though they are the same temperature?
Because the metal pole absorbs the heat energy from your hand alot faster.
When boiling a pot of noodles, describe where conduction takes place.
The pot (metal) conducts the heat from the stove.
When boiling a pot of noodles, explain where radiation takes place.
The heat from the stove is transfered through radiation waves.
Burning yourself on a grill is an example of what energy transfer? A. Radiation B. Convection C. Conduction
C.conduction
What does convection look like to you?(no wrong awnsers.)
How do you cook a hotdog with conduction ?
you use a fork to flip
The pot (metal) conducts the heat from the stove.
A solid (conductor) typically with a metal.
The heat from the stove is transfered through radiation waves.
True
The tides are caused by what? A. Radiation B. Convection C. Conduction D. None of the above
D. (None of the above)the moons pull causes tides.
What are every day thing you use that involves convection?(no wrong answers)
Air Conditioning.
What does conduction look like?
True or false: Conduction produces heat when you rub your hands together
False, friction causes heat when you rub your hands together. Conduction is the transfer of heat between two objects.
True or false: Radiation needs air to take place.
False
Solar pannels use what type of energy? A. Radiation B. Convection C. Conduction
A.radiation.
