The length of mercury column containing mercury in a glass thermometer is 5cm when thermometer is in contact with water at its triple point , calculate the measured temperature when the mercury column is 6cm and find the length of the mercury column when it is at steam point

What will be the change of temperature for 300 gr of iron (Fe) which have gained 2000 cal? (cFe= 0.11 cal/groC)

Calculate the quantity of heat absorbed by 3 kg of copper when heated from room temperature to 70oC. (ccu= 0.092 cal/groC)

What will be the change of temperature for 300 gr of iron (Fe) which have gained 2000 cal?

For a thermodynamic system, isobaric coefficient of volume expansion (a) and isothermal compressibility (b) are defined as

a=(1/v) (dv/dT)_p    b= -(1/v) (dv/dp)_T

Show that for an isochoric change, b dp = a dT.
