fluorescence
emission of radiations from a substance during illumination by radiations of higher frequency
superconductivity
property of some pure metals and their alloys at extremely low temperatures of having negligible resistance to the flow of an electric current
fatigue
the progressive decrease of a property as a result of repeated stress
elastivity
the tendency of a body to return to its original size or shape after having been deformed
diamagnetic
if a material is feebly repelled by a magnet
conductance
the property which permits the flow of current under the action of a potential difference is called
thermal conductivity
the rate of flow of thermal energy through a material in the presence of a temperature gradient is called
accumulation
the property by virtue of which a body resist any attempt to change its state of rest or motion is called
incandescence
the emission of light by a material cause of its high temperature is known as
the passage of white light into a glass
the violet color travels slower than the red color
adhesion
interaction between the surfaces of two closely adjacent bodies which causes them to cling together is known
malleability
the property of metals that allows them to be drawn into thin wires beyond their elastic limit without being rupture is called
brittle
solids which break above the elastic limit are called
charge
the property of some elementary particles that causes them to exert force on one another is known as
viscosity
the property of fluids by virtue of which they offer resistance to flow is known as
capacitance
the property of an isolated conductor to store electric charge is
temperature
the property of an object that determines the direction of heat flow when in contact with another object is called
isotropic
if the properties of a body are the same in all directions ,it is called
thermoduric
when a body resistant to heat, is called
