Problem

In a constant-pressure gas thermometer the coefficient of cubical expansion of the working gas is measured to be

3.4\times10^{-3}\,\text{K}^{-1}

at an unknown reference temperature

T_{0}

. (a) Determine the value of

T_{0}

in kelvin. (b) If the gas occupies

250\,\text{cm}^{3}

at this reference temperature, calculate its volume when the thermometer is placed in steam at

127^{\circ}\text{C}

while the pressure is still kept constant.
