In a mercury thermometer the ice point (lower fixed point) is
marked as 10º and the steam point (upper fixed point) is
marked as 130º. At 40ºC temperature, what will this
thermometer read

The correct value of 0°C on Kelvin scale will be

On a new scale of temperature (which is linear) and called
the W scale, the freezing and boiling points of water are 39°
W and 239° W respectively. What will be the temperature on
the new scale, corresponding to a temperature of 39° C on
the Celsius scale-
