Properties of Matter
100
Anything that has mass and takes up space.
What is matter?
100
What is the formula for finding the volume of a regular shaped object?
What is V= L x W x H?
100
All matter is made up of these.
What is more than 100 pure elements?
100
The definition of volume.
What is the amount of space an object takes up or occupies?
100
This property of water defines its density.
What is 1 g/mL?
200
The measure of the amount of mass per unit volume.
What is density?
200
Name two units of measurement for mass.
Kilograms, grams, pounds, ounces, etc.
200
This describes a change in matter that can be observed without changing the substance.
What is a physical change?
200
We use this tool to determine the volume of a liquid.
What is a graduated cylinder?
200
This is the charge of all elements in their natural state. Explain why.
What is neutral because elements in their natural state are made of equal number of protons and electrons which have opposite charges?
300
The smallest part of an element that has particles.
What is an atom?
300
The formula used to determine mass if you know the other two variables.
What is density times volume?
300
List 5 examples of a physical property
Mass, Color, Texture, Luster, Density, Boiling Point, Melting Point, State at room temperature.
300
The definition of a meniscus and how is it used?
What is the curved upper surface of a column of liquid? You measure the volume of liquid by reading the bottom of the meniscus.
300
These are 3 physical properties of the pure element Gallium.
What is it has a low melting point (will melt in your hand!), it is shiny, it is non-toxic, and it is a metal?
400
What is an element?
A substance that cannot be separated into simpler substances.
400
The formula for density.
What is D= m/v, density= mass divided by volume?
400
Water is best classified as which of the following: a. an atom b. an element c. a compound d. a mixture
What is C. a compound?
400
This is why a unit of mass is preferred over a unit of weight when dealing with science.
What is mass is the amount of matter in an object or substance and does not change no matter where it is in the universe? Weight changes depending on the force of gravity acting upon the object or substance.
400
The measure of the pull of gravity on an object.
What is weight?
500
Name the particles in an atom, and give their respective locations and charges.
What are protons (positive), neutrons (neutral), electrons (negative)? The protons and neutrons are located in the nucleus. The electrons are located in the electron shield which surrounds the nucleus.
500
The answer to the following: A cube with a 2 cm long side has a mass of 4g. Will it float in water? Explain.
What is YES. Volume = Length x Width x Height. The volume of the cube is 8cm cubed (2cm x 2cm x 2 cm). Density = mass / volume 4g/8cm cubed = 0.5g/cm cubed. The density of the cube is half the density of water (1g/mL) thus it WILL float.
500
Describe the arrangement and movement of atoms in each of the 3 states of matter.
In a solid, atoms are densely packed together, but not touching, and are vibrating. In a liquid, the atoms are slightly further apart and slide past each other. In a gas, the atoms are much further apart and are moving at a high rate of speed, bouncing off of each other and the container they are in.
500
A piece of gold has a volume of 32 cubic cm and a density of 19.3 g/cubic cm. Determine the mass.
m = D x v. m = 19.3 g/cubic cm x 32 cubic cm. m = 617.6 g
500
This is a chemical property of matter.
What is the ability to burn or change into a new substance?
