Amorphous : solid particles that have no pattern or ordered arrangement of molecules
Crystalline : solids whose particles are arranged in an orderly, three dimensional fashion
Atom : the smallest unit of an element, but still has to maintain the properties of that element
Molecule : at least two atoms that are attracted and bonded to each other
Surface Tension : force that acts on the surfaces of liquids, water has more of this than alcohol
Viscosity : when a liquid resists to flow it has this; water has less of this than maple syrup, and oil has more this than vinegar
Evaporation : the physical change of a substance from a liquid to a gas
Boiling : The physical change of a liquid to a vapor throughout the liquid. Water starts ___ at 100 degrees Celsius
Condensation : the physical change from a gas to a liquid. The particles of the water in the air lose energy, slow down, attract, and they stick together to form a drop of water
Solid : one of the three states of matter. This one has a definite shape and volume. This is because the substances molecules are very close and vibrate in place and do not have enough energy to move past each other
Liquid : one of the three states of matter. This one does not have a definite shape, but a definite volume. The molecules have enough energy to move past each other, but never escape their attraction with each other
Gas : one of the three states of matter. This states' molecules have enough energy to escape their attraction with one another and spread out to fill the space that they are in
States of Matter : the physical state of a substance, may change depending on the movement of the molecules
Temperature : the average kinetic energy of the molecules in a substance
Volume : how much space a substance takes up
Mass : how much stuff is in an object, and is measured on a balance which compares different masses. The unit that is used to measure is grams
Weight : the gravitational pull on an object; it is measured with a spring scale in Newtons (N)
Pressure : the amount of force put on an are of surface (how much the gas particles hit the surface)
Heat : the transfer of energy from a substance with a higher temperature to a substance with a lower temperature
Melting : the physical change of state in which a solid will become a liquid because of added energy. When the substance is heated, the molecules vibrate faster, causing them to escape their attraction and move past each other. The ____ point of water is 0 degrees Celsius
Freezing : The physical change of state in which a liquid becomes a solid. When energy is taken away, the molecules slow down and have a stronger attraction to each other and vibrate in place.
Sublimation : the change of state from a solid that directly turns to gas. Dry ice is an example
Melting Point : the specific temperature at which a substance turns from a solid to a liquid. When enough energy is added to a substance the particles move quicker and move past each other
Freezing Point : the specific temperature in which a substance changes from a liquid to a solid. When energy is taken away the molecules slow down and have a closer attraction. The ____ of water is 0 degrees Celsius
Endothermic : when energy is gained for the substance to change it's state
Exothermic : when energy is lost for the substance to change it's state
Boiling Point : specific temperature at which a liquid boils; the molecules gain enough energy to break their attractions and move so fast they rise and turn to a gas
Energy : _____ can be added or removed from a substance and it determines the state of matter.
Conduction : in _______ faster - moving molecules contact slower slower - moving molecules and transfer their energy
Speed Up : in conduction, the slower moving molecules ______ and the faster moving molecules slow down
Kinetic : Temperature is a measure of the average _____ energy of the atoms or molecules in a substance
Transfer : Heat is the _____ of energy from a substance at a higher temperature to a substance of a lower temperature
Conductors : Some materials are better ______ of heat than others
