This is the approximate mass of one grain of rice
What is one gram
100
This unit of force was named after a famous scientist. First name: Isaac
What is the newton
100
These are the two possible units for density
What are g/mL or g/cm3
100
Buyancy is the measure of the ________________ a fluid exerts on a submerged object.
What is upward force
100
Water has a specific heat of 4,184 J/kgC. Gold has a specific heat of 129 J/kgC. Which material will take less energy to heat up?
What is water
200
There are this many grams in a kilogram
What is 1,000
200
Objects in motion have kinetic energy. Objects that are off the ground but not falling have this kind of energy.
What is potential energy
200
This is the formula for density
What is density = mass/volume
200
Whose principle states that the buoyant force is equal to the weight of the fluid displaced by an object.
Who is Archimedes
200
A rock's mass is 60 g. It's volume is 15 mL. What is it's density? Make sure to use the correct units!
What is 4 g/mL
300
This is the smallest amount of any element you can have. Everything in the world is made up of them.
What are atoms
300
This is the flow of thermal energy - always from hot to cold
What is heat
300
True or false: A small gold coin has the same density as a large gold brick
What is true
300
This is what happens when the buoyant force is less than the weight of the object
What is the object sinks
300
What is the volume of a box with the dimensions 5 cm x 10 cm x 4 cm. Be sure to use the correct units!
What is 200 cm3
400
Atoms in this PHASE of matter hold their volume, but not their shape
What is the liquid phase
400
This physical property tells you how much energy it takes to raise the temperature of a material
What is specific heat
400
This is the method used to measure the volume of irregularly shaped objects, like a pencil
What is the displacement method
400
An object with an average density less than the density of water will do this
What is float
400
An object with a density of 0.7 g/mL is placed in a fluid with a density of 1 g/mL. Will the object sink or float?
What is float
500
Chlorine gas and Sodium metal combine to form this common compound
What is NaCl, or table salt
500
This law states 'Energy can never be created or destroyed, just converted from one form to another'
What is the law of conservation of energy
500
Density can vary for two reasons. One is that atoms may be packed tightly or loosely - This is the other reason.
What is that atoms have different masses
500
To make a dense object float, you must decrease it's density by increasing this measurement
What is it's volume
500
An object that weighs 100 newtons on land only weighs 75 newtons when submerged in water. What is the buoyant force on the object?
What is 25 newtons?
