Look at the picture. Which key concept does it best represent?
Temperature is a measure of the average speed of the molecules of a thing.
When a thing gets hotter, it's molecules are moving faster. When a thing gets colder, its molecules are moving slower.
Things are made of molecules (or other types of atom groups).
Look at the picture. Which key concept does it best represent?
All living things are made of cells.

In our SIM, molecules change to a yellow color when they are moving faster and gray when they are moving slower.
What is true about this SIM picture?
It is showing molecules moving faster at cooler temperatures.
It is showing molecules moving faster at warmer temperatures.
It is showing that themal energy and temperature are the same number.
The molecules in the jar are moving around at different speeds.
How would you calculate the average speed of the molecules if the individual speeds are:
1, 2, 3, 3, 4, 4, 7, 8
1 x 2 x 3 x 3 x 4 x 4 x 7x 8= 16, 128
16,128/ 8= 2016
The average speed is 2016
1 + 2 + 3 + 3 + 4 + 4 + 7+ 8= 32
The average speed is 32
1 + 2 + 3 + 3 + 4 + 4 + 7+ 8= 32
32/ 8 = 4
The average speed is 4
