States of Matter
Do crystalline solids melt at a distinct temperature?True or False?
True
Matter exists in different forms. What are the forms?
Solid, Liquid, Gas
What is the definition of kinetic energy?
Kinetic energy is energy of motion.
What is the definition of potential energy?
Potential energy is energy that is stored.
__________ affects the pressure of a gas in a tire.
Temperature
Amorphous solids particles form a pattern. True or False
False
A solid has a definite shape and a definite volume. What do the particles look like?
The particles that make up a solid are packed very closely together. They can only vibrate in place, meaning they move back and forth slightly.
What measures the average kinetic energy of the particles in an object or substance?
What is water's boiling point? 2 answers
212 Degrees Fahrenheit, 100 Degrees Celsius
What is Boyles Law?
The relationship between the pressure and the volume of a gas is called Boyle's Law.
What are the two major characteristic properties of liquids
surface tension and viscosity
A liquid has a definite volume but no shape. What do the particles look like?
particles in a liquid are always in contact with one another. They are packed almost as closely together as those in a solid. However, the particles in a liquid are not fixed in place.
When a crystalline solid melts at a specific temperature, what is that called?
Melting Point
What are the two main types of vaporization?
Boiling and evaporation
What's the name of the French scientist who examined the relationship between the temperature and volume of a gas?
Jacques Charles
Salt, sugar, and snow are examples of?
crystalline solid
What type of solid is glass?
It is amorphous because of its particle arrangement and the fact that it does not melt at a specific temperature.
What is water's freezing point? 2 answers
0 Degrees Celsius or 32 Degrees Fahrenheit
When does vaporization occur?
It occurs when the particles in a liquid gain enough energy to move independently and away from each other.
What units are the pressure of gas measured?
pascals (Pa) or kilopascals (kPa)
