Conduction
-The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential
Example: Teaspoon dipped in hot water-Touching a stove and being burned
-Ice cooling down your hand-Boiling water by throwing a red hot piece of iron in it
Convection
-The movement caused in a fluid of hotter and less dense material to rise, and colder, denser material to sink under the influence of gravity, which causes the transfer of heat
Example: Hot air rising, cooling, and falling (currents) -An old-fashioned radiator –A pot boiling water
Radiation
-Energy as electromagnetic waves
Example: -Heat from the sun warming your face -Heat from a light bulb -Heat from a fire
-Heat from anything else which is warmer than its surroundings
Fahrenheit
-It’s a scales based on 32 for the freezing point and 212 for the boiling point
-Daniel Gabriel Fahrenheit invented the mercury thermometer in 1714 and developed the temp. scale
-Generally used in English speaking countries in 1970
-William John Macquorn Rankine used it as the basis of his absolute temperature scale
Celsius
-temperatures of the freezing and boiling points of water are divided into 100 degrees
-The freezing point is taken as 0 degrees Celsius and the boiling point as 100 degrees Celsius
-widely known as the centigrade scale
-Swedish astronomer Anders Celsius established the scale in 1742
-Temperatures on the Celsius scale can be converted to equivalent temperatures on the Fahrenheit temperature scale
Kelvin
-The temperature scale is named after the British mathematician and physicist William Thomson Kelvin
-proposed in 1848
-is often used in astronomy and space science
-The Kelvin scale is similar to the Celsius scale
-the zero point in the Kelvin scale is the coldest possible temperature (absolute zero)
Laws of Thermodynamics
1st law
-Energy can be
