Matter, Mixing, and Dissolving
WHMIS stands for
What is Workplace Hazardous Materials Information Systems
The formula to calculate density is
What is mass/ volume (mass divided by volume)?
The thickness or thinness of a liquid
What is viscosity?
The force opposing the buoyant force
What is gravity?
The formula to calculate pressure
What is pressure = force/area (force divided by area)?
The difference between homogenous and heterogenous is
What is homogenous looks all like one substance and in heterogenous you can see the different parts of the mixture.
Out of the 3 states of matter (solid, liquid, gas) this state is the most dense.
What is a solid?
The relationship between viscosity and temperature
What is when temperature increases the viscosity decreases and as it cools the viscosity increases?
When an object is more dense than water it would
What is sink?
In a pneumatic system a force is exerted in a closed space by
What is air?
The difference between solvent and solute is
What is solvent - a substance that dissolves a solute to form a solute solute - a substance that dissolves in a solvent
The units for measuring density in a solid is
What is grams/centimetre cubed?
Viscosity in a gas when temp is decreases
What is as gases are cooled, particles slow down and the viscosity decreases?
The instrument to measure density of a liquid
What is a hydrometer?
The definition of hydraulic systems is
What is a device that transmits an applied force through a liquid to move something else by means of pressure?
A solution that is said to be saturated is
What is saturated cannot dissolve any more solute at a specific amount of solvent at the same temp?
Mass is
What is the amount of matter in a substance
Archimedes was trying to determine
What is volume and/or if the crown was made of pure gold?
An example of a hydraulic system and an example of a pneumatic system
What is garbage trucks (hydraulic) What is buses (pneumatics)?
Describe the 5 points of the particle theory/model
What is 1. all substances are made up of particles 2. particles in a pure substance are the same. Different pure substances have different particles 3. particles have space between them 4. particles always move and increase/decrease in movement because of temperature 5. particels in a substance attract each other. Strength of attractive forces depends on particle type.
An astronauts weight changes when on the moons surface but not his mass because
What is because he doesn't have gravity to make mass
On the side of ships there are plimsoll lines to measure
What is if a ship is safely loaded?
An unbalanced force is
What is an individual force not being acted upon by a force of equal magnitude or opposite direction?
