Energy Transfer and Heat Capacty

Shrinks to 4 C

Expands from 4-0 C

Happens a few ways

-Conduction- Particles run into each other

Conductors and insulators are opposites

Convection- transfer of thermal energy by movement of particles from one place to another

Radiation- thermal energy transfer by electromagnetic waves

Thermal energy is related to work

Heat is a form of energy and is produced regularly

Mechanical equivalent of heat is

1 cal=4.186 J

1 kcal= 4186 J

1 C= 1 kcal

heat is represented in equations by a Q

adding heat to a system makes it positive

taking it away makes it negative

Lets first remember that energy and work are related. Q(heat) can be converted to joules from calories

next we need to remember our work equation. work= Fxd

then rearrange the equation to determine distance(height)
