Thermal Energy PPT 1 Flashcards
joules experiment
he set up a falling weight that caused a paddle wheel to turn and he saw that the friction between the wheel and water caused the temp of water to rise
how does heat travel
high temperature to low temperature
waht is kinetic theory
- all matter consists or tiny particles
- electrostaticl forces, both attractive and repulsive, exist between these particles
- particles move constantly in a random manner
- collisions between particles involve no loss of kinetic energy.
- distance between particles in gas are large compared to the size of particles.
what is thermal energy
thermal energy is the sum of the kinetic and potential energy of all of the particles in that object
what does KE determined
energy of objects in motion
what is potential energy
energy stored in the particles
what is temperature
measures average kinetic energy of objects particles
what is heat
described thermal energy being transferred between objects because of a difference in their temperature
Joules(J)
when does heat stop trANSFERING
when tempreatures are equal, so there is no body in higher or lower temperature
what is absolute zero
-273.15 degrees C
0K
the lowest temperature possible where are particles moving the asbolute slowest they can
what happens as object cools down
particles slow down
celcisu -> kelvin
celsius + 273.15 = kelvin
kelvin -> celsius
kelvin - 273.15 = celsius
