Flashcard on Temperature and Molecules

Front

What is Temperature?

Back

A measure of how hot or cold something is

Front

You place food coloring into a cup of hot water and a cup of cold water. In which cup will the food coloring spread out faster?

Back

Hot Cup- the molecules move faster in a hot substance than a cold substance

Front

What is a molecule?

Back

A group of atoms joined together in a particular way

Front

Which sample has more kinetic energy? How do you know? Options: A- It is a lighter color and the key states that the lighter the color, the more KE the molecules have, B- It is a darker color, Both samples have the same kinetic energy, Neither sample has kinetic energy

Back

It is a lighter color and the key states that the lighter the color, the more KE the molecules have.

Front

What is temperature related to?

Back

The movement of molecules

Front

What is absolute zero?

Back

When no molecules are moving in a substance

Front

Can absolute zero be reached according to the article?

Back

NO

Front

Where are the coldest temperatures measured?

Back

Space -454 degrees Fahrenheit

Front

What is an average?

Back

A number that summarizes a set of data and can be computed by adding all the numbers in a list and then dividing by the number of numbers in the list.
