Definitions
What is the definition of plasma?
What is a high-energy state of matter where electrons are separated from atoms.
define evaporation
Change from liquid to gas
Which state of matter has no fixed shape or volume?
gas
give me the most common example of sublimination
dry ice
What is entropy?
randomness
A non-Newtonian fluid is a fluid whose viscosity changes in response to applied force, unlike Newtonian fluids which have a constant viscosity.
define freezing
Change from liquid to solid; releases heat.
Which state of matter has particles in fixed positions?
solid
give me one example of an endothermic change
melting
what is the boiling point of water in Kelvin?
373.1 K
What is the definition of matter?
Anything that has mass and takes up space.
define melting
Change from solid to liquid; requires heat.
What state of matter has a definite shape and volume?
solid
give me one example of a chemical change
rust formation
what is mass measured in?
Grams or kilograms
what is the definition of a gas?
A state of matter with no fixed shape or volume; particles move freely and are widely spaced.
define deposition
Change from gas directly to solid
What do we call the change from a liquid to a gas?
evaporation/vaporization
give me one example of condensation
water droplets on cold glass
what is the boiling point of water in Fahrenheit?
212 Degrees
what is the definition of a liquid?
A state of matter with a definite volume but no definite shape; particles are close but can move past each other.
define sublimination
Change from solid directly to gas
What is it called when a gas changes directly into a solid?
give me one example of deposition
frost formation
A state of matter at near absolute zero where particles behave as a single quantum entity (super atom)
Bose-Einstein Condensate
