Triple Point

Two ideal gas thermometer A and B use oxygen and hydrogen respectively . The following observations are made: Temperature, Pressure therometer A, Pressure therometer B Triple point of water, 1.250xx10^(5)Pa , 0.200xx10^(5)Pa Normal melting point of sulphur, 1.797xx10^(5)Pa , 0.287xx10^(5)Pa (a) What is the absolute temperature of normal melting point of sulphur as read by thermometers A and B ? (b) What do you think is the reason for the slightly different answers from A and B ? (The thermometers are not faulty). what further procedure is needed in the experiment to reduce the discrepancy between the two readings.

Assertion At triple point, three stated (solid, liquid and gas) may co-exist simulaneously. Reason For water, the values of pressur and temperature corresponding to triple point are 10 mm of Hg and 273.16 K.

The pressure on a sample of water at its triple point is reduced while the temperature is held constant .Which phases changes are favoured? (1) melting of ice (2)sublimation of ice (3) vaporization of liquid water

A constant volume thermometer registers a pressure of 1.500 xx 10^4 Pa at the triple point of water and a pressure of 2.050 xx 10^4 Pa at the normal boiling point. What is the temperature at the normal boiling point?

Which of the following statement is correct ? a) The triple point of water is 253.16 K. b) Burns from steam are less severe than those from boiling water. c) Ethyl alcohol expands less than mercury for the same rise in temperature. d) When fully inflated balloon is immersed in cold water, it will contract.

A constant volume gas thermometer using helium records a pressure of 20.0k Pa at the triple point of water, and a pressure of 14.3 k Pa at the temperature of 'dry ice' ( solid CO_(2) ) . What is the temperature of dry ice?

The electrical resistance in ohms of a certain thermometer varies with temperature ac cording to the approximate law: R =R_(0)[1+alpha(T-T_(0))] The resistances is 101.6 Omega at the triple-point of water 273.16K , and 165.5 Omega at the normal melting point of lead (600.5K) . What is the temperature when the resistance is 123.4 Omega ?
