Ideal-gas equation and absolute temperature

In the ideal gas equation, could Celsius temperature be used instead of Kelvin if an appropriate numerical value of the gas constant R is used,?

For an ideal gas the fractional change in its volume per degree rise in temperature at constant pressure is equal to [T is absolute temperature of gas]

At a constant pressure, of the following graphs that one which represents the variation of the density of an ideal gas with the absolute temperature T, is

A container is filled with 20 moles of an ideal diatomic gas at absolute temperature T. When heat is supplied to gas temperature remains constant but 8 moles dissociate into atoms. Heat energy given to gas is

Statement-1: The de-Broglie wavelength of a molecules (in a sample of ideal gas ) varies inversely as the square root of absolute temperature The arm velocity of a molecules (in a sample of ideal gas ) depend in temperature.

A sample of an ideal gas occupies a volume V at pressure P and absolute temperature T. The masss of each molecule is m, then the density of the gas is

Two moles of an ideal mono-atomic gas undergoes a thermodynamic process in which the molar heat capacity 'C' of the gas depends on absolute temperature as C=(RT)/(T_(0)) , where R is gas consant and T_(0) is the initial temperature of the gas. ( V_(0) is the initial of the gas). Then answer the following questions: The equation of process is
