What is temperature coefficient (T.C.)?

The resistance of a conductor at 15^(@)C is 16 Omega and at 100^(@)C is 20 Omega . What will be the temperature coefficient of resistance of the conductor ?

At room temperature (27^(@)C) , the resistance of a heating element is 100 Omega . What is the temperature of the element if the resistance is found to be 117 Omega , given that temperature coefficient of the resistor material is 1.70xx10^(-4) .^(@)C^(-1) .

The positive temperature coefficient of resistance is for

For a certain reaction the variation of rate constant with temperature is given by the equation ln k_(t) = lnk_(0) + ((ln 3)t)/(10) (t ge 0^(@)C) The value of temperature coefficient of the reaction is

The temperature dependence of the emf of a standard electrochemical cell is given by E=1.02-4.0xx10^(-5) (T-20)-9.0xx10^(-7) (T-20)^(2) where, T is in .^(@)C and E is in volts. The temperature coefficient of the emf at 30^(@)C is :

What do you mean by temperature coefficient of the velocity of sound ? Explain.

Rate constant of reaction increases (2^(n)) times. Temperature coefficient of this reaction is '2' initial and final temperature of the reaction is 25^(@)C and 115^(@)C . What will be the value of 'n'?

A potential difference is applied across the filament of a bulb at t = 0 and it is maintained at a constant value while the filament gets heated to its equilibrium temperature. We find that final current in the filament is one fifth the current drawn at t = 0 . If the temperature of filament at t = 0 is 20^(@)C and the temperature coefficient of resistivity at 20^(@)C is 0.004(.^(@)C)^-1 , find the final temperature of the filament.
