Duh what are the primary states of matter
Solid, liquid, and gas
The energy of possition
The energy of motion
Equation to convert celcius to kelvin
C + 273
Equation to convert fahrenheit to celcius
5/9 ( F - 32)
First law of thermodynamics
Energy can neither be createx or destroyed, only transformed in nature.
Equation for energy transfer
The internal engery of an object
The energy transferred to or from an object (heat)
The external work performed on the object
The four main ways to effext heat transfer
- 1. Conduction
- 2. Convection
- 3. Radiation
- 4. Evaporation/condensation
The main means for heat transfer between objects. Directly transferred between hot and cold molecules
It invloves mixing of fluid molecules at differnt temperatures. Both liquids and gases are effect. Air is heated in one location and then moved to another.
Heat transfer that occurs without direct physical contact. Suxh as the sun warming the earth.
The change of state from liquid to gas and the process requires heat energy. Must come from it surroundings.
Is a form of vaporization where heat is taken from the surrounding air of the liquid, and cools it. Nonheaded humidifiers cool the gas above.
The opposite of evaporation. Gaseous vapor turns back into a liquid and heat given bqck to the surroundings.
The change of heat from the solid to liquid state.
The extra heat needed to completely change a solid into a liquid.
Latent heat of fusion
The opposite of melting. During this process heat energy is transfered from a liquid back to the enviroment.
