a) An alcohol in glass thermometer is calibrated by reference to the freezing and boiling points of water. When placed in water containing ice the level of the mercury is

10 mm above the reservoir at the base of the thermometer. When placed in boiling water the level of the mercury is 180 mm above the reservoir at the base of the thermometer. If the thermometer is placed in water heated to 65 °C what would be the height of the alcohol in the thermometer? ) Pt-resistance thermometer displays a linear relationship between resistance and temperature. If it has a resistance of 30 µn at 77 K and a resistance of 130 µn at 273K, what temperature is being measured if the thermometer has a resistivity of 158 µN?
