|
Temperature |
Measure of hotness of a body |
|
|
Heat |
It is a form of energy transfer btw two system by virtue of temperature difference |
|
|
Boyles law |
Pressure inversely proportional to volume. PV=constant |
|
|
Charles law |
Volume is directly proportional to temperature. |
|
|
Ideal gas law |
PV=MRT |
|
|
Thermal expansion |
Rate of increase in dimension of a body to increase in temperature |
|
|
Heat capacity |
Amount of heat required to increase the temperature of whole substance |
|
|
Specific heat capacity |
Amount of heat required to increase temperature unit mass of a body by one unit. |
|
|
Molar specific heat capacity |
Amount of heat required to increase the temperature of 1 mole of a substance by one unit. |
|
|
Change of state |
Transition from one state to another state. |
|
|
Melting point |
Temperature at which the solid and liquid coexist in thermal equilibrium with each other |
|
|
Boiling point |
Temperature at which liquid and vapour state coexist in thermal equilibrium with each other. Boiling point increases with Temp |
|
|
Latent heat |
The amount of heat energy per unit mass transfered during change of state of substance |
|
|
Regalation |
Phenomenon in which ice melts when pressure is applied and again freeze when it is removed |
|
|
Conduction |
Heat transferred btw two adjacent part of a body due to temperature difference. Transfer by molecular collision without actual movement of molecule. |
|
|
Convection |
Transfer of heat by actual movement of molecule |
|
|
Radiation |
Transfer of heat through electromagnetic wave without requirement of medium. |
|
|
Weins displacement law |
The product of wavelength corresponding to maximum energy and the absolute temperature of black body is constant. |
|
|
Stefan's law of radiation |
The total radiant energy emitted per second from unit area of the surface of black body is directly proportional to fourth power of its absolute temperature. |
|
|
Newtons law of cooling |
The rate of lose of heat is directly proportional to difference of temperature btw the body and its surrounding. |
