Chapter 10-1

Do the water molecules in a cup of hot soup or in a glass of ices lemonade move faster?

hot cup of soup because the warmer a molecule is, the faster it moves

Heat is the transfer of energy between objects with different ___________.

temperatures.

absolute zero

the temperature at which an object's energy is minimal (-273.13* C or 0 K)

A __________ is a device that measures temperature.

thermometer

A degree Celsius is nearly ______ times as large as a degree Fahrenheit.

two

_________ is a measure of the average kinetic energy of an object's particles.

Temperature

Explain how your precautions would differ if you were preparing to enter a chamber at 100K as opposed to one at 100*C.

You would need to prepare for extremely cold temperatures for 100K (because 100K = -173*C = -279.4*F). For the other room, you would need to prepare for extremely hot temperatures (100*C = the room at 100*C

thermometer

temperature

a measure of the average kinetic energy of all the particles within an object

The lowest temperature possible is ________ ______ and is at ___ kelvin.

absolute zero and is at 0 kelvin.

On the Celsius temperature scale, water freezes at ___ degrees and boils at ____ degrees.

freezes at 0 degrees and boils at 100 degrees.

A degree in ________ is equal to a degree in Celsius.

kelvin

At absolute zero the particles of an object have no _______ _______ to transfer.

kinetic energy
