Matter Vocabulary
Everything that has mass and takes up space
Matter
A substance that dissolves in another
Solute
Objects that stay on top of a liquid do this.
Float
What is volume?
The amount of three dimensional space an object takes up.
Pressure is the amount of force applied to a given area. It is measure in...
Pascals or Newtons per meter squared.
The state of matter that has a definite shape and volume and has particles that are tightly packed together
Solid
A mixture that appears to be a single substance, where particles of 2 or more substances are distributed evenly throughout each other.
A solution
Buoyant force would be measured with this unit.
Newtons
True or False: Density is a property of matter that is used to identify unknown matter. Density is like a fingerprint, no two types of matter have the exact same density.
True.
What unit is often used by scuba divers to measure pressure?
atm or atmospheres
The smallest part of an element that still has the properties of the element
Atom
The ratio of solute to solvent in a solution.
Concentration
The buoyant force is necessary for objects to do this.
Float
Density is calculated using what formula?
Mass divided by volume
An object exerts a force of 9000N over 500 m2. How much pressure does it exert?
18 Pa
Amount of matter packed inside a certain amount of space
Density
For most substances, an increase in temperature has this effect on solubility.
Increases the solubility
If the weight of an object is greater than the buoyant force than an object will do this.
Sink
Calculate the mass of a substance with a density of 15g/mL and a volume of 100 cm3.
1 cm3 = 1 mL therefore the mass would be 150 g
What type of system uses pressured gas to do work?
Pneumatics
The fourth state of matter when a gas has been ionized/charged.
Plasma
Calculate the concentration of a solution that has 75mL of water and 15g of sugar.
0.2g/mL
True or false: A fresh raw egg will float in water.
False: A fresh raw egg will sink on its side in water.
If a person has a mass on 68kg on Earth, what is their mass on the moon?
68kg - MASS NEVER, EVER, EVER CHANGES! THE AMOUNT OF MATTER IN AN OBJECT DOES NOT CHANGE BECAUSE OF GRAVITY. ONLY WEIGHT CHANGES BECAUSE OF GRAVITY.
Calculate the pressure exerted by an object with a mass of 1750kg and an area of 200m2.
