100
Particles of gas move in this manner
What is fast and randomly, colliding with the walls of their container?
100
These measurements are required to find density and this is the formula for density
What is Mass and Volume?
Density = Mass / Volume
100
This is the definition of matter
What is anything that has mass and volume?
100
These phases of matter are ranked from least to most motion of particles
What is solid, liquid, and gas?
100
Water is an element or a compound
What is a compound?
200
This is caused by gas particles colliding with the walls of their container
What is pressure?
200
This is the density of a toy car that is 200 grams and 20 mL
What is 10 g/ml
200
Elements are composed of this
What is one type of atom?
200
These phase changes occur as a solid changes into liquid then a gas and have this change in thermal energy
What is melting then evaporating and an endothermic change?
200
This is an independent variable
This is a dependent variable
What is
Independent- variable you change
Dependent- variable you measure
300
This is Boyle's Law
What is the pressure and volume of a gas are inversely proportional (as one increases, the other decreases, and vice versa)?
P1V1=P2V2
300
This unit of measurement varies based on location in relation to Earth
What is weight?
300
This is an example of a heterogeneous mixture and how you can separate it
Answers will vary, what is anything that you can see individual components?
Can be separated by filtration
300
These phase changes occur as a gas changes into liquid then solid and have this change in thermal energy
What is condensation then freezing and an exothermic change?
300
This is the difference between replication and repetition
What is
Replication- a different scientist performing the same experiment to verify results
Repetition- the same scientist performing multiple trials of the same experiment to verify results
400
This is Charles' Law
What is the volume and temperature of a gas are directly proportional (an increase in temp leads to an increase in volume)?
V1/T1 = V2/T2
400
This is the volume of an object that is 7 g/mL and 7 g
What is 1 mL?
400
This is an example of a homogeneous mixture and how you can separate it
Answers will vary, what is anything you cannot see individual components?
Can be separated by distillation
400
The phase changes are in the graph below at these points
What is B and D?
400
This is how to find the volume of an irregularly shaped object
What is water displacement?
500
This is the Gas Law that explains the fizz when you open a soda can
What is Boyle's Law?
500
This is the definition of mass, how we measure it, and the units
What is
Definition- the amount of matter in an object
Tools to measure- scale, triple beam balance
Units- grams?
500
These are the components of a solution and their descriptions
What are solute and solvent?
Solute is what gets dissolved, solvent is substance that dissolves the solute
500
This is a description of what is happening at each point in the graph below
What is
A: gas
B: condensing
C: liquid
D: freezing
E: solid
500
This is thermal energy and how it's different than temperature
What is thermal energy is total energy of the motion of particles- both potential energy and kinetic energy. Temperature is the measure of kinetic energy of the particles?
