100
The formula for Density
What is Mass/Volume
100
The definition for electrical conductivity.
What is the amount of current that can pass through a wire?
100
100 degrees celsius 212 degrees farenheit
What is the boiling point of water.
100
0 degrees celsius and 32 degrees farenheit.
What is the freezing point of water?
100
The amount of a solid, liquid, or gas that can dissolve in another liquid.
What is Solubility?
200
You have the mass but need to find the volume of an irregular solid to get calculate density.
What is using water displacement?
200
The two wires used in the electrical conductivity lab.
What are copper and nichrome wire?
200
What is something that can affect the boiling point?
What is the elevation or atmospheric pressure.
200
The freezing point of a liquid is always really cold--- True or false. Give an example.
False, the freezing point of substance of A and B were 46 degrees celsius and 55 degrees celsius.
200
This is the substance that is dissolved in the liquid.
What is a solute?
300
You have a substance with a mass of 99 g and a volume of 11 ml. what is the density?
What is 11 g/ml.
300
What is most conductive? Aluminum 991 (mA), Brass 979 (mA), Copper 995 (mA), Nichrome 743 (mA), Tin 966 (mA)
Copper
300
Another word for boiling point
What is the condensation point or vaporization point?
300
The flat line on a graph shows this on a temperature vs time graph. Go up and show an example and point out the freezing and boiling point.
What is a phase change?
300
This is the substance that does the dissolving.
What a solvent?
400
The volume is 1000 ml, and the density is .74 g/ml what is the mass?
740 g
400
How can you tell which wire is more conductive?
The brightness of a bulb, or measure the current using an ammeter.
400
The molecules move extreamly fast and are spaced far apart in the gas phase because of this.
What is an increase in thermal energy?
400
Another word for the freezing point.
What is the Melting point?
400
Why did we use CO2 gas in our solubility of gas lab?
The water wasn't completely saturated with CO2 gas so more could dissolve into the liquid.
500
The density is 8.9 g/ml and the mass 45 g. What is the Volume
5.06 ml
500
To test electrical conductivity of different materials you must keep these other variables constant.
What are the length of wire, number of cells in a circuit, and the thickness of wire.
500
The temperature during a phase change (like boiling point) stays constent because of this.
What is Latent Heat?
500
Slow down and get closer together.
What is happens to the molecules when thermal energy decreases in a substance?
500
What are a couple of things that can affect the solubility of a substance?
The temperature that the substance is dissolved in and the kind of solvent that is used.
