Chapter Two chemistry note


·         Energy is the ability to do work
·         Potential energy is stored
·         Kinetic is motion
·         1 Cal = 1 kcal = 1000 cal
·         Typical energy daily requirement: Female 2200 and Male 3000 energy in kcal
·         The Celsius degree is almost twice the size of the Fahrenheit degree; 1 C = 1.8 F
o   F to C: TF = 1.8 (TC) + 32
o   C to F: TC = TF-32/1.8
·         To calculate Kelvin, add 273 to the Celsius temperature
·          Specific heat is the amount of heat needed to raise the temperature of 1g of a substance by 1C
·         Heat of fusion is the amount of heat needed to separate the particles of a solid
