1
Q

joules experiment

A

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

2
Q

how does heat travel

A

high temperature to low temperature

3
Q

waht is kinetic theory

A
• 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.
4
Q

what is thermal energy

A

thermal energy is the sum of the kinetic and potential energy of all of the particles in that object

5
Q

what does KE determined

A

energy of objects in motion

6
Q

what is potential energy

A

energy stored in the particles

7
Q

what is temperature

A

measures average kinetic energy of objects particles

8
Q

what is heat

A

described thermal energy being transferred between objects because of a difference in their temperature

Joules(J)

9
Q

when does heat stop trANSFERING

A

when tempreatures are equal, so there is no body in higher or lower temperature

10
Q

what is absolute zero

A

-273.15 degrees C
0K
the lowest temperature possible where are particles moving the asbolute slowest they can

11
Q

what happens as object cools down

A

particles slow down

12
Q

celcisu -> kelvin

A

celsius + 273.15 = kelvin

13
Q

kelvin -> celsius

A

kelvin - 273.15 = celsius
