States of Matter
The state of matter that has a fixed shape and a fixed volume.
What is a solid?
Theory that relates all matter and how it behaves.
What is the kinetic theory?
The upward force a fluid exerts on an object.
What is the buoyant force?
The unit for pressure.
What is pascal?
A block of iron has a mass of 23 grams and a volume of 9.9 mL. What is the density?
2.32 g/mL
The state of matter with indefinite shape and definite volume.
What is a liquid?
The point when an ice cube's molecules have enough energy to become water.
What is the melting point?
The principle that states that buoyant force is equal to the fluid the object displaces.
The law that states if you change the volume of a gas, the pressure will also change.
At 76 kPa, the volume of a gas is 0.30 L. If the temperature remains constant and the pressure is changed to 61 kPa, what is the new volume of the gas?
0.37 L
The most common state of matter in the universe.
What is plasma?
The point when a liquid's molecules have enough energy to become steam.
The principle that states when you apply pressure to a fluid the pressure is transmitted throughout the fluid.
What is Pascal's principle?
The law that states if temperature of a gas increases, so does the volume.
What volume will 50 L of a gas at 725 kPa occupy if the pressure is increased to 760 kPa?
47.7 L
The arrangement of molecules are completely random, allowing them to "flow".
What is gas?
The state of matter where molecules are able to slide past each other, but settle on the bottom of containers.
What is a liquid?
The term to describe liquids like syrup and molasses.
What is viscous (viscosity)?
The law that can be written as V1 / T1 = V2 / T2.
What is Charles's Law?
If you have a balloon with an initial volume of 50 L and a temperature of 298 K and the final temperature of the balloon is 232 K what is the final volume?
38.9 L
The sun is an example of this state of matter.
As the temperature increases, molecules ________. As the temperature decreases, molecules _______.
Spread apart/Expand, Get closer together/Contract
An example of this principle are car jacks.
What is Pascal's principle?
The behavior of gases.
What is (indefinite shape, indefinite volume, spread apart molecules, high energy)?
A 2 L balloon has an initial temperature of 200 K. If the volume is increased to 5 L, what is the new temperature of the balloon?
500 K
