How does heat flow? | Hot to cold |
Kinetic Molecular Model= | All particles are in constant motion, thus they have have kinetic energy. |
Internal Energy= | Sum of all PE and KE in an object |
Thermall Energy is measured when | it is transferred from ojne system to another |
Heating and Cooling are the action of | transferring particle kinetic energy |
A loss of thermal energy is accompanied by | a fall in temperature |
A gain in thermal energy is accompanied by | a rise in temperature |
The temperature of an object is directly related to the average | kinetic energy of the object |
in 1714, the first temperature scale was created by | Gabriel Farenheit |
In 1742, the second scale was invented by | Anders Celcius |
In 1848, ______ created the final scale | Lord Kelvin |
Thermal Expansion happens on the _____level | particle |
Electrical Resistance increases with temperature because | the particles move more randomly |
Viscosity is | the measure of the resistance that liquids exert |
Heat is | the quantity of thermal energy that flows from one place to another |
Conduction= | when two objects of unequal temperature touch, thermal energy moves form the hotter object to the cooler one |
Thermal Equillibrium is when | two objects have the same temperature |
Conduction is for | solids |
Convection is for | liquids |
Radiation is for | waves |
Specific Heat | the heat capacity per gram in the material |
Specific heat formula= | Q=cmt |
Sublimation is | when a solid id transformed to a gas |
Deposition is | when gas is transformed to a solid |
Triple Point | Temp at which a solid, liquid, and gas can exist simultaneously |
Critical Point | point where a substance will always be a gas no matter what the pressure is |
