Is the thermometer reading of the temperature of air (in shade) the same as the temperature of sand or water? What do you think is the reason for this? And why does the temperature have to be measured in the shade?

Is the temperature of air in the closed glass vessel/bottle the same as the temperature taken in open air? (i) What do you think is the reason for this? (ii) Do we ever come across this phenomenon in daily life?

Give reason We use thermometers and not our hands to measure temperature

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.

A body having a temperature of 27^@C is kept in a room having a temperature of 27^@C . Does the body emit any radiation in this case when the room temperature is the same as body temperature ?
