Unit 1:
The phase changes that occur when a solid absorbs energy.
What is melting and evaporation?
What is the term used to identify how quickly an element goes through radioactive decay?
half-live
What is three things that you can do in order for a solute to dissolve faster?
The rate of increasing, decreasing, or constant speed and can change if the speed and/or the direction changes.
What is acceleration?
Explain how heat is transferred through radiation.
What is no contact (rays and waves)?
The phase change that occurs when energy is removed from a gas.
What is condensation and freezing?
What is the difference between fission and fusion?
Fusion is combing atoms and fission is breaking apart atoms.
what is the difference between a solute & slovent?
solvent is the base, solute is what you add in.
The rate of an objects motion.
What is speed?
The type of heat transfer occurring when you use a lamp to heat a cup of water.
What is radiation?
Explain how a liquids kinetic energy compare to a solids.
What is the kinetic energy in a liquid being higher than a solids?
What is the purpose of finding a half-life?
to determine the age of radiation
Something you could do to an electrolyte solution in order for a light bulb to shine brighter?
What is adding more solute.
The rate of an objects motion and its direction.
What is velocity?
The type of heat transfer occuring when you stick a metal spoon into a cup of hot water and the handle heats up.
What is conduction?
Determines the state of matter of a substance.
What is the speed and attraction of the particles?
What is the reason some elements go through radioactive decay?
They are trying to become more stable atoms of other elements
The Dead Sea contains so much dissolved salt that it allows people to float easily in it, what type of solution is the Dead Sea?
What is saturated?
Newton's law that deals with unbalanced forces acting on an object that equals the objects mass times it's acceleration.
What is the 2nd Law?
The type of heat transfer process that allows for warm air currents to rise and cool air currents to sink.
What is convection?
Describe how a liquid can change into a solid in terms of energy and molecular motions.
What is removing the energy and decrease the molecular motion?
What is the half life of this element, after 120 days, 200 grams of an element x has decayed to 12.5 grams?
30 days.
The maximum amount of solute that can dissolve at a specific temperature.
What is saturation?
The Newton's Law that represents A golf ball sitting on the tree.
What is the 1st Law?
The endothermic processes.
What is melting, vaporization, and sublimation?
