What is science
100
a factor that can change in an experiment
What is a variable
100
mass/volume
the amount of matter in a given space
What is density
100
that which has mass and occupies space
What is matter
100
the change of a substance from a liquid to a gas
What is evaporation
200
the science of matter and energy and their interactions
What is physics
200
the amount of 3-dimensional space occupied by an object or the space that something contains
What is volume
200
form when electrons are shared between atoms
What is a covalent bond
200
a fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors
What is plasma
200
the process by which a liquid or solid changes to a gas
What is vaporization
300
the study of the properties of matter and how matter changes
What is chemistry
300
a body of matter without definite shape
What is mass
300
of definite shape and volume
What is solid
300
describes a process in which heat is absorbed from the environment
What is endothermic
300
a change directly from the solid to the gaseous state without becoming liquid
What is sublimation
400
a series of steps that scientists use to answer questions and solve problems. Ask a question, form a hypothesis, test hypothesis, analyze results, draw conclusion, communicate results.
What is the scientific method
400
the force exerted by a mass as a result of gravity
What is weight
400
a substance in the fluid state of matter having no fixed shape but a fixed volume
What is liquid
400
chemical reaction in which energy is primarily given off in the form of heat
What is exothermic
400
a substance in the solid state turning into a liquid state substance
What is melting
500
a proposal intended to explain certain facts or observations
What is a hypothesis
500
the tendency of a body to maintain is state of rest or uniform motion unless acted upon by an external force
What is inertia
500
a fluid in the gaseous state having neither independent shape nor volume and being able to expand indefinitely
What is gas
500
the process of changing state of matter
What is condensation
500
a substance in the liquid state turning into a substance in the solid state
