Chapter 16 Vocab Flashcards
Kinetic Theory 3 Statements
An explanation of how particles in matter behave.
1) All matter is composed of small particles (atoms, molecules, and ions)
2) These are in constant, random motion
3) These particles are colliding with each other and the walls of their container
Heat of Fusion
The amount of energy required to change a substance from the solid phase to the liquid phase at its melting point
Plasma
Matter of positively and negatively charged particles
Thermal Expansion
An increase in the size of a substance when the temperature is increased
Heat of Vaporization
The amount of energy required to change a substance from the liquid phase to the gaseous phase
Boyle’s Law
As pressure increases, volume decreases.. As pressure decreases, volume increases
Charles’ Law
The volume of a gas increases when the temperature increases at constant pressure
Solid
Closely packed particles, specific shape
Liquid
More freely moving particles, no exact ordered arrangement/shape
Gas
Particles are far apart, no definite volume or shape
Archimedes Principle
If the buoyant force of the liquid is equal to the weight of the object, the object floats. If the buoyant force of the fluid is less than the weight of the object, the object sinks
Pascal’s Principle
Pressure applied to fluid is transmitted throughout the fluid
Bernoulli’s Principle
As the velocity of a fluid increases, the pressure exerted by the fluid decreases
