Important Questions on Thermal Physics
Two ideal gas thermometers A and B use oxygen and hydrogen, respectively. The following observations are made:
|
Temperature |
Pressure thermometer A |
Pressure thermometer B |
|
Triple-point of water |
||
|
Normal melting point of sulphur |
What is the absolute temperature of the normal melting point of sulphur as read by thermometers A and B? What do you think is the reason behind the slight difference in answers of thermometers A and B ? (The thermometers are not faulty). What further procedure is needed in the experiment to reduce the discrepancy between the two readings ?
Correct the following statement:
Equal masses of all gases under identical conditions contain the same number of molecules.
Correct the following statement:
Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of atoms.
