Composition
The smallest unit of an element that maintains the properties of that element.
What is an Atom?
This state of matter has a definite shape and a definite volume.
What is a solid?
The process of a liquid becoming a gas at the surface of the liquid.
What is Evaporation?
The amount of matter in a given space, calculated as mass divided by volume.
What is Density?
This principle explains why heavy ships float: the buoyant force equals the weight of the displaced fluid.
What is Archimedes' Principle?
A substance made of two or more elements that are chemically combined.
What is a compound?
The most common state of matter in the universe, found in stars and lightning.
What is a Plasma?
When a solid changes directly into a gas without becoming a liquid first.
What is Sublimation?
A characteristic that can be observed without changing the substance into something new.
What is a Physical Property?
According to this principle, as the speed of a moving fluid increases, its pressure decreases.
What is Bernoulli's Principle?
This type of mixture is uniform throughout, like salt water or air.
What is a homogeneous mixture?
Particles in this state are close together but can slide past one another.
What is a liquid?
The temperature at which a liquid becomes a solid.
What is the freezing point?
Flammability and reactivity are examples of this type of property.
What is a Chemical Property?
This principle states that pressure applied to a fluid is transmitted equally throughout the fluid (used in hydraulic lifts)
What is Pascal's Principal?
These are the two parts of a solution, one does the dissolving, and the other is dissolved.
What are solute and solvent?
This state has no definite shape or volume and is highly compressible.
What is a Gas?
This occurs when a gas loses thermal energy and becomes a liquid.
What is condensation?
This law states that matter is neither created nor destroyed during a chemical reaction.
What is the Law of Conservation of Mass?
This property describes a liquid's resistance to flowing.
What is Viscosity?
A mixture where particles are large enough to settle out over time, like Italian salad dressing.
What is a suspension?
The measure of the average kinetic energy of the particles in an object.
What is temperature?
During a phase change, the temperature of a substance does this.
What is stays the same?
A change in color, the production of a gas, or the formation of a precipitate are signs of this.
What is a Chemical Change?
An upward force exerted by a fluid on an object placed in it.
What is Bouyant Force?
