Topic 5 - Temperature and Particle Theory Flashcards
1
Q
what happens to the particles when you increase the temperature?
A
particles gain more energy, so move more quickly or vibrate more.
2
Q
what happens to the particles when you decrease the temperature?
A
particles lose energy, so move less quickly or vibrate more.
3
Q
what is absolute zero?
A
the coldest that anything can ever get (0 kelvin or -273 degrees celsius). particles have as little energy in their kinetic energy stores as possible
4
Q
how do you convert from degrees celsius to kelvin?
A
add 273
5
Q
what is energy in particles’ kinetic energy store proportional to?
A
the temperature of a gas (kelvin) is proportional to the average energy in the kinetic energy stores of its particles
