heat
the transfer of energy between objects at different temperatures
thermal energy
the total energy of the particles that make up a substance
direction of heat transfer
higher temperature to lower temperature
what 2 things determine the amount of thermal energy
temperature & how much of the substance you have
conductor
transfer of thermal energy from one substance to another through direct contact
conductor
conducts thermal energy well
insulator
does not conduct thermal energy well
convection
transfer of thermal energy by the movement of a liquid or gas
convection current
circular motion of liquids or gases due to density differences caused by temp. differences
radiation
transfer of energy through matter or space as electromagnetic waves
greenhouse effect
warming due to trapped radiation by atmosphere
thermal conductivity
the rate at which a substance conducts thermal energy
specific heat capacity
the amount of heat energy needed to change the temperature of 1 kg of a substance by 1 degree celsius
calorimeter
a device used to determine the specific heat capacity of a substance
calorie
the amount of energy needed to change the temperature of 0.001 kg of WATER by 1 degree celsius
kilocalorie
1000 calories, used on food labels, Calorie (capital C)
Difference between temp. and thermal energy
temp = average kinetic energy
thermal energy = the total energy of a substance
temperature
expressed in degrees fahrenheit, degrees celsius, or Kelvin
thermal energy
expressed in joules
heat
expressed in joules or calories
