Density and Pressure Problems
It is the density of an object with a mass of 18g and a volume of 2 cm^3.
What is 9 g/cm^3?
All matter is made up of these tiny things that are invisible to the naked eye.
What are particles?
This term refers to the strength of the connection between particles of the same substance.
What is cohesion?
It is defined as any substance with no fixed shape.
What is a fluid?
Between gold, a stone, water, and oxygen, it is the one with the highest density.
What is gold?
It is the mass of an object with a density of 3.5 g/cm^3 and a volume of 10 cm^3.
What is 35 g?
What is identical?
This term could be demonstrated by water sticking to the side of a glass.
What is adhesion?
This is the unit that Pressure is measured in.
What are Pascals?
It is the property of fluids that is commonly thought of as "thickness".
What is viscosity?
It is the amount of pressure (in Pascals) exerted when 10N are applied to 0.5 m^3.
What is 20 Pa?
This is what you would find between particles.
What is empty space?
This term is what allows water striders to "walk on water".
What is surface tension?
Two objects with the same mass are placed in water. Object A causes the water level to rise 300mL. Then, object A is removed and object B is put in. It causes the water level to rise 500mL. It's the object with the higher density.
What is object A?
This process or term can be used to find the volume of an irregularly shaped object, like a rock, by placing it in water.
What is displacement?
It is the force (in Newtons) exerted when 19 Pa are applied to an area of 3 m^3.
What is 57 N?
Particles are held together by very strong...
What are electric charges?
This term refers to the process of an airplane condensing outside oxygen before letting it enter the inside of the plane.
What is pressurization?
This principle allows us to explain how a hydraulic jack, with a small piston, can support the mass of a car, through the use of a larger piston.
What is Pascal's Principle?
It is defined as the mass of an object per unit of volume.
What is density?
When placed in water, a rock makes the water level go from 100mL to 450mL. The rock has a density of 2.13 g/cm^3. What is the mass of this rock?
What is 745 grams?
This process will make particles move faster and farther apart.
What is adding heat?
Pneumatics systems work because of this characteristic of gas, meaning its volume can be decreased.
These are the two ways you can increase pressure in a container holding gas.
What are increasing temperature and decreasing volume?
This Law states that when heat is added to a gas, particles begin to move faster, resulting in more energy.
What is Gay-Lussac's Law?
