Chapter 6 NEWBOOK Flashcards
a measure of how hot (or cold) something is
temperature
an increase in the size of a substance in response to an increase in temperature of the substance
thermal expansion
the temperature at which molecular energy is at a minimum
Absolute zero
the energy transferred between objects that are at different temperature
heat
the kinetic energy of a substance’s atoms
thermal energy
the transfer of energy as heat through a material
thermal conduction
a material through which energy can be transferred as heat.
thermal conductor
a material that reduces or prevents the transfer of heat.
thermal insulator
the transfer of thermal energy by the circulation or movement of a liquid or gas
convection
the transfer of energy as electromagnet waves
radiation
the quantity of heat required to raise a unit mass of homogeneous material 1 K or 1 degrees C in a specified way given constant pressure and volume
specific heat
physical form of matter ( solid, liquid, and gas)
states of matter
the change of a substance from one physical state to another
change of state
a substance that reduces the transfer of electricity, heat, or sound.
insulator
a machine that transform heat into mechanical energy, or work
heat engine
a temp. increase in a body of water that is caused by human activity and that has caused harmful effects on water quality and on the ability of that body of water to support life.
thermal pollution
