Humidity refers to the amount of water vapor in the air. Absolute humidity measures actual water vapor in grams per cubic meter. Relative humidity compares current moisture to maximum capacity at given temperature
Temperate climates occur between 23.5° and 66.5° latitude. Temperatures vary widely throughout the year with distinct seasons. Influenced by latitude, sea currents, wind direction, continentality and altitude
Absolute zero is the lowest limit of thermodynamic temperature scale. International standard is 0 kelvin, −273.15°C or −459.67°F. Kelvin and Rankine scales set their zero points at absolute zero
Heat capacity is the amount of heat needed to raise a unit temperature change. SI unit is joule per kelvin (J/K). Specific heat capacity is heat capacity divided by mass
Australia's climate is influenced by subtropical high pressure belt. Most of the country is desert or semi-arid. Only south-east and south-west corners have temperate climate. Northern part has tropical climate between grasslands and desert
Fill 12-quart pot ⅔ full with cold water. Place on high heat for 5-10 minutes to reach 212°F (100°C). Water goes through quiver, sub-simmer, simmer, and rolling boil stages. Use lid to hold heat and prevent splashing
