Matter
What is matter ?
Anything that takes up space
What charge do electrons have
negative
What is volume, and how is it different from mass and weight?
Volume is the amount of space occupied by an object or substance. Mass is the measure of the amount of matter in an object, typically measured in grams or kilograms. Weight, on the other hand, is the force of gravity acting on an object and is measured in newtons or pounds.
What is density ?
is a substance's mass per unit of volume.
Are you allowed to bring your backpack to class ?
No
What is mass ?
The amount of matter
What charge do protons have ?
Posiotive
What is the formula for volume ?
Volume = length x width x height
What is the formula for Density ?
Density = Mass/volume
Who is Bunz favorite science teacher ?
Ms.Tye
What is volume ?

What is the charge of neutrons ?
Neautral
Explain how you can find the volume of an irregularly shaped object using the water displacement method.
You can place the irregular object in a container of water, and the amount of water displaced (the rise in water level) is equal to the volume of the object. Measure the volume of the water using a graduated cylinder or measuring cup.
A substance has a mass of 75 grams and a volume of 25 cm³. Calculate the density of the substance.
The density of the substance is 3 g/cm³.
What should you bring to class ? (3 things)
A notebook, pencil and a good attitude.
What is density ?
The amount of matter in a certain space
If an atom has 7 neutrons how many electrons does it have ?
7
How does changing the shape of a container affect its volume, even if the amount of substance it holds remains the same?
Changing the shape of a container does not affect the amount of substance it holds, but it can affect the volume, as the space it occupies can change. For example, a tall and narrow container may have the same amount of substance as a short and wide container, but they will have different volumes because of their different shapes.
A block of aluminum has a mass of 100 grams and a volume of 20 cm³. Calculate the density of the aluminum block.
The density of the aluminum block is 5 g/cm³.
Does Bunz like it hot or cold ?
Cold
What is weight ?
The amount of gravity acting on an object
Carbon has an atomic number of 6 and an atomic mass of 12 how many neutrons does it have ?
6
You have a glass that is 10 centimeters tall, and you fill it with water up to the 8-centimeter mark. What is the volume of water in the glass?
The volume of water in the glass is 8 cubic centimeters (cm³).
A plastic ball has a mass of 60 grams and a density of 0.3 g/cm³. Calculate the volume of the plastic ball.
The mass of the wooden block is 320 grams.
