Weight, Mass, Volume
What is the force of gravity acting on an object?
Gravity
True or False: Particles of a solid are usually less densely packed than particles of a liquid
False : Particles of a solid are usually MORE densely packed than particles of a liquid
Define Buoyancy
The upward supportive force of an object in a fluid
Write out the equation of Volume...Volume =
Volume = length x width x height
Write out the equation for Density...Density =
Density = Mass / Volume
Why do different types of water (ex. freshwater, saltwater...) hold objects up differently.
Every fluid has a different buoyancy
What was the colour of
Play-doh that sunk during our Buoyancy experiment
Green
When you take a bath, the water rises because it can not occupy the same space as you. This is known as...
Displacement
A property that makes a substance distinct from others is known as?
Characteristic Property
What is less dense...oil or water?
Oil
The amount of matter that makes up an object or substance is?
Mass
An empty container has a mass of 25g. When 70mL of oil is added to the container the total, the total mass is 90g. Calculate the density of the oil.
Mass of Oil = Total mass - Container Mass
Mass of Oil = 90g - 25g = 65g
Density of Oil = mass / volume
Density of Oil = 65g / 70mL = 0.928g/mL
Founds in a submarine, this chamber takes in water to keep the submarine stable or to help is dive below the surface.
Ballast Tanks
A container has a length of 5cm, width of 10cm, and a height of 20cm. What is the volume of the container (include units)
1000mL
Wood is less dense than water?
True - Wood: 0.12g/mL vs Water: 1.0g/mL
Why does a boat float?
The buoyant force equals the weight of the water displaced by the object.
OR
The force of gravity acting downward is the equal to the buoyant force acting upward.
