The temperature will stay the same

If the particles of an object decrease speed what will happen to the temperature of the object?

The temperature will stay the same

Which molecules are moving faster?

Both are moving at the same speed

Your hot dog will have faster moving molecules.

The molecules in both hot dogs will move at the same speed.

Your hot dog will have slower moving molecules.

Your brother's hot dog will have faster moving molecules.

Look at the picture. Which key concept does it best represent?

Things are made of molecules (or other types of atom groups).

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.

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 warmer temperatures.

It is showing molecules moving faster at cooler 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 + 2 + 3 + 3 + 4 + 4 + 7+ 8= 32 32/ 8 = 4 The average speed is 4

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
