Ch.5 Sec.1

Question 1

Temperature

Answer 1

Measure of the average kinetic Energy of all the particles that make up an object

Average kinetic Energy of atoms

Ex. 28 degrees C

Question 2

Thermal Energy

Answer 2

Sum of kinetic Energy and Potential Energy of the particles that make up an object

P.E. + K.E.

Ex.

Question 3

Specific Heat

Answer 3

The amount of heat needed to raise the temp to 1kg to 1 degree C

Heat energy that raises 1kg to 1degree C

Ex.

Question 4

Calorimeter

Answer 4

Used to determine the specific heat of materials

Determines specific heat

Ex. Sample placed in chamber

Question 5

Heat

Answer 5

Energy that is transferred between objects due to a temp difference between those objects

Temperature difference causes energy transferred

Ex. Warm objects heat cool objects but never the other way around

Question 6

Coolant

Answer 6

A substance that can absorb a great amount of thermal energy with little change in temp

Substance that absorbs thermal energy

Ex. Water

Question 7

Difference between
Temp and thermal
Mass and thermal

Answer 7

Thermal energy depends on temp

Thermal also depends on mass

Question 8

What does sand heat faster than water?

Answer 8

Sand has more thermal energy

Question 9

Why is water used as a coolant?

Answer 9

It can absorb thermal energy without a large change in temp
