A mercury thermoeter read `80^(@)C` when the mercury is at `5.2cm` mark and `60^(@)` when the mercury is at `3.9cm` mark. Find the temperature when the mercury level is at `2.6cm` mark.

A faulty barometer contains certains amount of air and saturated water vapour . It reads 74.0cm when the atmospheric pressure is 76.0cm of mercury and reads 72.10cm when the atmospheric pressure at the air temperature=1.0cm of mercury. Find the length of the baromerer tube above the mercury level in the reservoir.

A barometer tube of length 90 cm contains some air above mercury. The reading of the mercury level is 74.8 cm when the atmospheric pressure is 76 cm and temperature is 30^@C . If the reading is observed to be 75.4 cm on some another day when temperature is 10^@C , then what will be true pressure?

The readings of a thermometer at 0^(@)C and 100^(@)C are 50 cm and 75 cm of mercury column respectively. Find the temperature at which its reading is 80 cm of mercury column ?

In a constant volume gas thermometer, the pressure of the working gas is measured by the difference in the levels of mercury in the two arms of a U-tube connected to the gas at one end. When the bulb is placed at the room temperature 27.0^0 C , the mercury column in the arm open to atmosphere stands 5.00 cm above the level of mercury in the other arm. When the bulb is placed in a hot liquid, the difference of mercury levels becomes 45.0 cm . Calculate the temperature of the liquid. (Atmospheric pressure = 75.0cm of mercury).

In a constant volume gas thermometer, the pressure of the working gas is measured by the differenced in the levels of mercury in the two arms of a U-tube connected to the gas at one end. When the bulb is placed at the room temperature 27.0^0 C , the mercury column in the arm open to atmosphere stands 5.00 cm above the level of mercury in the other arm. When the bulb is placed in a hot liquid, the difference of mercury levels becomes 45..0 Cm . Calculate the temperature of the liquid. (Atmospheric pressure = 75.0cm of mercury).
