Heat Transfer Flashcards
All ____________ has heat.
Matter
Heat is a form of energy
What is heat caused by?
Heat is caused by particles in an object that vibrate.
Does the object become warmer or colder the faster the particles vibrate?
The object becomes warmer the faster the particles vibrate.
Why is heat transfer always happening?
Because particles of an object are always moving.
Heat transfer always flows from _____ to _____.
Hot to cold.
What is known as equilibrium?
Once two objects reach the same temperature, heat transfer will stop.
What are the three key ways that heat transfers?
- Conduction
- Convection
- Radiation
How is heat transferred in conduction?
With solid objects, heat transfers when the objects come into direct contact with other things.
Explain how heat transfer works with liquids and gases in the process of convection.
Liquids and gases flow or are fluid so heat transfer happens when warmer, less dense particles rise and cooler, more dense particles sink.
Heat can also be transferred through _____ (distance) in the form of _____. This process is known as radiation. All objects ____ ____ or emit, some heat. All objects also take in, or _____ heat.
Heat can also be transferred through 𝕤𝕡𝕒𝕔𝕖 (distance) in the form of 𝕨𝕒𝕧𝕖𝕤. This process is known as radiation. All objects 𝕘𝕚𝕧𝕖 𝕠𝕗𝕗 or emit, some heat. All objects also take in, or 𝕒𝕓𝕤𝕠𝕣𝕓 heat.
