Thermal Physics

What is temperature?

heat and energy

What is the difference between head and temperature?

Temperature is a measurement of the kinetic movements of atoms. But heat is the transfer of thermal energy (energy from atoms)

Kinetic energy in something hot is ___.

Fast

Kinetic energy in something cold is ___.

Cold

What is the kinetic molecular theory?

The more energy a particle has, the faster it moves.

What are the three ways thermal energy move?

Conduction, convection and radiation

What is conduction?

Transfer by direct contact

What is convection?

Movement of liquid and gas

What is radiation?

Movement of photons 

What is a insulator?

Does not allow head molecules to flow fast.

What is a conductor?

Allow heat molecules to flow fast.

What are good conductors?

Diamond, water, silver, copper, and steel.

What are bad conductors?

Polystyrene, glass wool, rubber, and wood.

What is a convection current?

A process where hot air/fluids circle around.

Surfaces good for absorbing?

Matte and black

Surfaces good for reflecting?

white and reflective

What is evaporation?

When particles with enough energy randomly escapes from liquid to gas.

Factors affecting evaporation?

current(wind), temperature, surface area and humidity?
