Matter
how much matter is in an object
What is mass?
one atom gives an electron to another atom to stabilize it ex. NaCl
What is an ionic bond?
molecular structure of water
What is polar covalent molecule?
chemical, nuclear, gravitational, elastic, magnetic
What are potential energy forms?
the lowest temperature possible; particles stop moving
What is absolute zero?
how much space an object takes up
What is volume?
equal sharing of electrons; forms between two nonmetals ex. H2
What is a covalent bond?
pH of water
What is 7?
mechanical, electrical, thermal, radiant, and sound
What are kinetic energy forms?
total kinetic energy of molecules in a substance/object/body
What is heat?
how compact something is based on its size and volume
What is Density?
unequal sharing of electrons where there are different electronegativities ex. H2O
What is a polar covalent bond?
tendency for molecules of the same kind to stick together
energy that something has due to position or shape; stored for later use
What is potential energy?
average kinetic energy of molecules in a substance/object/body
What is temperature?
molecules grouped closely together; molecules move around easily; molecules move around freely
What is the molecular pace of a solid, liquid, and gas?
elements heavier than these two elements were forged by the stars
What is hydrogen and helium?
attraction between molecules that are not alike
What is adhesion?
energy of motion
What is kinetic energy
amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius
What is specific heat?
matter cannot be created or destroyed, but states of matter can change
What is the law of conservation of mass?
to create this element hydrogen fuses together
What is helium?
amount of heat needed to raise the temperature of one gram of water by one degree Celsius
total energy in an isolated system is constant
What is conservation of energy?
the three transfers of heat energy and three examples of each
What is radiation (electromagnetic waves; sun), conduction (physical contact; hand touching hot stove), and convection (fluid; convection currents)?
