VOCABULARY
FOR UNIT 6
TEMPERATURE
MEASURE OF HOTNESS OR COLDNESS OF A SUBSTANCE
HEAT
THE TOTAL ENERGY OF THE ATOMS WITHIN A SUBSTANCE
CONDUCTION
TRANSFER OF HEAT THROUGH DIRECT TOUCH
CONVECTION
WHEN A LIQUID/GAS IS HEATED, THE HOTTER THE LIQUID/GAS RISES
RADIATION
HEAT TRANSFER THROUGH ELECTROMAGNETIC WAVES
THERMAL CONTRACTION
WHEN ENERGY (HEAT) DECREASES, THE SPACE BETWEEN THE PARTICLES DECREASES
POTENTIAL ENERGY
STORED ENERGY THAT RESULTS FROM THE POSITION OR SHAPE OF AN OBJECT
KINETIC ENERGY
ENERGY THAT AN OBJECT HAS DUE TO ITS MOTION
FACTS
TEMPERATURE
IS MEASURED WITH A THERMOMETER IN DEGREES CELCIUS OR FAHRENHEIT
TEMPERATURE
IS NOT THE SAME AS HEAT
HEAT
IS MEASURED IN JOULES INSTEAD UNLIKE TEMPERATURE
HEAT
IS ALSO MEASURED ON A CALORIE METER INSTEAD OF A THERMOMETER
CONDUCTORS
ALLOW HEAT ENERGY TO PASS THROUGH THEM
INSULATORS
DO NOT ALLOW HEAT ENERGY TO PASS THROUGH THEM
EXAMPLES OF CONDUCTORS
- Silver
- Stainless steel
- Copper
- And other types of metals
EXAMPLES OF INSULATORS
- Wood
- Wool
- Straw
- Paper
