Temperature Notes

Symbols and Units

Temperature

Symbols/Units :

Note-taking Column

Question:

Summary: Include: How are temperature and average kinetic energy related? Which way does heat ALWAYS

flow and when will heat stop flowing?

Internal Energy Notes

Symbols and Units

Internal Energy Symbol

:

Internal Energy units:

Note-taking Column

Question:

Summary: Include: As the particles move faster what happens to the total internal energy and therefore the

temperature? Friction causes the internal energy to increase which does what to the temperature of the object?

Heat Notes

Symbols and Units

Heat Symbol :

Heat units:

Note-taking Column

Question:

Summary: Include: How are heat and temperature different? If you add heat to an object what happens? If

heat is removed from an object what happens?

Specific Heat Capacity Notes

Symbols and Units

Specific Heat Capacity

Note-taking Column

Substance Specific Heat Capacity Substance Specific Heat Capacity

Aluminum 899 Lead 128

Copper 387 Mercury 138

Glass 837 Silver 234

Gold 129 Steam 2010

Ice 2090 Water 4186

Iron 448

Summary: Include: How many joules of energy does it take to increase the temperature of one kilogram of

aluminum by one degree Celsius? Water has a larger specific heat capacity than aluminum this means it takes

more or less energy to change its temperature?

Find:

Summary: Include: Why is QIN water and QOUT copper? If there were a third substance how would you know

which side to add the third substance to (would you place it on the IN side or the OUT side)?
