Q.

What are diathermal walls, diabatic walls, and adiabatic walls?

Q. Calculate the freezing point of a solution containing 60g of glucose (Molar mass = 180 g $Mo{l}^{-1})$ in 250 g of water.
$(k_{f}ofwater=1.86Kkgmo{l}^{-1})$

Q. Thermodynamics is concerned with:

1. The energy changes in a system
2. The total energy of a system
3. The rate of chemical change
4. The mass changes in nuclear reactions

Q.

Increase in enthalpy of the surroundings is equal to decrease in enthalpy of the system. Will the temperature of system and surroundings be the same when they are in thermal equilibrium?

Q. What is the meaning of Thermodynamical controlled product and kinetically controlled product?

Q.

In an isothermal process system is in contact with outside heat reservior and the change occur slowly so as to facilitate to adjust temp and in adiabatic process system is isolated. Then my question is even if adiabatic system is isolated then how the temperature changes.

Q.

what is the difference between "thermodynamics in PHYSICS" and "thermodynamics in CHEMISTRY"

Q. State whether true or false :

1. True
2. False

Q. what is sign convention related to first law of thermodynamics

Q. Assertion :The ratio of heat of vaporisation and the normal boiling point of a liquid is approximately 88 J/mol. Reason: This is Trouton's rule derived by experimental data.

1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
3. Assertion is correct but Reason is incorrect
4. Assertion is incorrect but Reason is correct

Q. A liquid-nitrogen container is made of a 1 cm thick styrofoam sheet having thermal conductivity 0.025 J s⁻¹ m⁻¹ °C⁻¹. Liquid nitrogen at 80 K is kept in it. A total area of 0.80 m² is in contact with the liquid nitrogen. The atmospheric temperature us 300 K. Calculate the rate of heat flow from the atmosphere to the liquid nitrogen.
