chapter 6 Flashcards
What is a measure of how hot or cold something is pacifically a measure of the average kinetic energy of the particles in a object
Temperature
What is an increase in the size of the substance in response to an increase in the temperature of the substance
Thermal expansion
What is the temperature at which molecular energy is at minimum a 0-0 kelvins on the Kelvin scale or -273.16 degrees Celsius on the Celsius scale
Absolute zero
What is the energy transferred between objects that are the different temperatures
Heat
What is the kinetic energy of a substance atoms
Thermal energy
What is the transfer of energy as heat through a material
Thermal conduction
What is a material through which energy can be transferred as heat
Thermal insulator
What is the transfer of thermal energy by the circulation o or movement of a liquid or gas
Convection
What is the transfer of energy as electromagnetic waves
Radiation
What is the quantity of heat required to raise a unit mass of homogeneous material one Kelvin or one degrees Celsius in a Pacific Way given constant pressure and volume
specific heat
What is the physical forms of matter which include solid liquid and gas
States of matter
What is the change of a substance from one physical state to another
Change of state
What is a substance that reduces the transfer of electricity heat or sound
Insulation
What is a machine that transforms heat into mechanical energy or work
Heat engine
What is a temperature increase in a body of water that is caused by human activity and that has a harmful effect on water quality and on the ability of that body of water to support life
Thermal pollution
