What is Mass?
The amount of stuff an object is made of
The volume that an object takes up
The number of particles in an object
The density of an object
What is volume?
The amount of stuff an object is made of
The amount of space an object takes up
Yhe opposite of density
The absolute density of an object.
If a substance is changing while you are watchiing it happening, which of the following is a possible clue that might tell you that it is a chemical reaction?
The object is cold
The object is melting
The object is blue
The object is fizzing
The difference between a chemical and a physical change is
Mass is lost during a chemical change but not a physical change
There is no difference.
A physical change is a change in the appearance of an object.
In a chemical change, a new substance is always made.
If wax is melting, is this a chemical change or a physical change?
Chemical Change
Physical Change

The red line
Gold has a density of 19.3 g/ cm3 . Which of the following is gold?
The Green Line
The Brown Line
The Red Line
None of the choices is gold.
Dissolving 5 grams of salt in 20 grams of water will create
Exactly 25 grams of saltwater because matter can not be created or destroyed.
Less than 25 grams of saltwater because dissolving means destroying.
More than 25 grams of saltwater because we are creating a new substance.
complete and utter destruction.
Adding 20 grams of baking soda to 200 grams of vinegar creates a lot of fizzing. Which of the following is true?
The mixture will be more than 220 grams because the bubbles add weight to the mixture.
The mixture will be exactly 220 grams due to the conservation of mass.
The mixture will be more than 220 grams because the density increases.
The mixture will be less than 220 grams because gas is released, and gases have mass.

In Unit 2, we learned that when matter is at any temperature,
The particles of that material are in constant motion.
The particles of solids do not move.
Gas molecules always move faster than solid particles.
bacon is delicious
When two substances are at the same temperature,
gas particles move faster
solid particles move faster
the particles of both substances move at exactly the same speed
they always have the same density
Gas pressure always results from gas particles
moving randomly and colliding with the particles around them.
sitting still
gas particles applying a force to the walls of the container.
escaping a container
sketch the curve that shows a change in gas pressure with a change in volume.
Draw the curve that shows a change in pressure with a change in temperature in Celsius.
Draw a curve that represents a change in gas pressure with a change in the number of gas particles.
