TEMP CELSIUS TO FAHRENHEIT; (1.8*C)+32=F

FAHREN TO CELSIUS:(F-32)/1.8=C
TO GET KELVIN: add 273.15 to celsius.
CELSIUS TO KEVIN: menos 273.
FORMULAS
Q= U-W
Q=MCAT
DEFINITIONS:
-THERMODYNAMICS:dexcribe the transfer of energy(deals with the relationship between heats and other forms of energy).-ENTROPY:the amount of disorder in a system.-ENTHALPY;change in heat or measure of heat content. -GLISS FREE ENERGY:amount of energy in a system that is available to do work. -ABSOLUTE ZERO:lowest temperature. -RADIATION:energy transmitted in waves. -CONDUCTION: transfer of energy. CONVECTION heat is transfered by mass or liquid. 1ST LAW: heat is a form of energy, conservation of energy, 2ND LAW:states that entropy of the universe always increases over time. 3RD LAW:entropy of a system approach a constant value of zero. ZEROTH LAW:if two systems are in thermodynaic equilibrio with a 3rd system then the two orginial are in thermal equilibrium with eachother. COMBUSTION: chemical reactions. CFC: Chemical compound made up of chlorine fluorine and carbon, gas in refrigerator. EFFICENCY;measure of how much work or energy is conserved in a process DEEP SEA AIR CONDITIONING: alternate energy system that uses cold water from the deep ocean HEAT: form of energy, that can be transfered from one object to other. PRESSURE; force per unit area. CALORIMETRY;measuring the heat transfer within a chemical reaction.

TEMP IS A MEASURE OF KINETIC ENERGY
A LIQUID THERMOMETER WORKS BECAUSE LIQUID EXPANDS WHEN WARM.
INCREASE IN HEAT IN SYSTEM; decreases entropy
HEAT IS A FORM OF ENERGY CONTAINED INSIDE THE BODY, WHEN 2 BODIES OF DIFFERENT TEMPS ARE IN THERMAL CONTACT ...
HEAT IS THE ENERGY TRANSFERED DUE TEMPERATURE DIFFERENCE
IS RELATED TO DEGREE OF HOTNESS.
SUBLIMATON OCCURS WHEN ice changes to gaseous water
FOUNDATION OF THERMODYNAMICS law of conservation of momentum
FATHER OF THERMO and 2nd law ; carnot.
