What is volume?
the amount of space an object takes up
100
What is mass?
Mass is the amount of matter in an object
100
What is density?
Mass per unit volume

Why can't you measure the volume of a rock with a metric ruler?
Because it is an irregular solid
300
How do you measure the volume of a regular solid.
length x width x height
300
What is the difference between mass and weight?
mass- amount of matter in an object weight- mass times the force of gravitational attraction
300
Why does a ballon filled with helium float in air
helium is less dense than the surrounding air
400
What is the metric and SI unit for temperature? What is the metric unit for time?
Degrees Celsius and Kelvin seconds
400
What is kinetic energy. Give an example of something that has kinetic energy.
Moving energy answers vary
400
How do you meaure the volume of an irregular solid. Be specific and list the steps
1) Fill graduated cylnder with water and MEASURE volume 2) Drop the object in and measure the new volume. 3) Subtract the two volumes
400
Does air have mass? Explain a demonstration or experiment to prove that air has mass.
yes deflated ball, inflate, calculate mass
400
How does a hot air balloon work?
Heated air is less dense than the surrounding air and will float.
500
If you wanted to measure the distance from Rutherford to NYC what metric unit would you use?
kilometers
500
Explain the relationship between temperature and kinetic energy
Hotter temps- more kinetic energy
500
Does air have volume? Explain a demonstration or experiment you could do to prove that air has volume. be specific
yes air has volume tissue demonstration

WHat is a meniscus? How should you read a graduated cylinder (3 things)
curved surface of water flat surface, eye level, meniscus

Why does diet coke float in water and regular coke sink in water. (be specific- full answer for credit)
diet coke is less dense that water so it floats in water. Regular coke is denser than water so it sinks in water. They both have the same volume but coke has a higher mass because it has sugar which has a higher mass than artificial sweetener.
