General Terms in Thermodynamics

The figure shows a peddle wheel couple to a mass of $12 \mathrm{kg}$ through fixed frictionless pulley. The paddle is immersed in a liquid of heat capacity $4200 \mathrm{J} {\mathrm{K}}^{-1}$ kept in an adiabatic container. Consider a time interval in which the $12 \mathrm{kg}$ block falls slowly through$70 \mathrm{cm}$.

(a) How much heat is given to the liquid ?

(b) How much work is done on the liquid?

(c) Calculate the rise in the temperature of the liquid neglecting the heat capacity of the container and the paddle

.

Time taken to heat water upto a temperature of$40°C$ (from room temperature) is $t_1$ and time taken to heat mustard oil (of same mass and at room temperature) upto a temperature of $40°C$ is $t_2$, then (given mustard oil has smaller heat capacity)
 

What is the thermodynamic system?

For the process to occur under adiabatic conditions, the correct condition is:

What is thermodynamics? 

Which is not the microscopic variable of the system?

What are the macroscopic variables of a thermal system?

What is an isolated system. Give its one example.

The real or imaginary surface that separates the system from its surroundings is called _____.

What are the constituents of a thermodynamic system?

Heat flows from _____ temperature to lower temperature. 

In thermodynamics, work done by a system is the total quantity of energy that the system and its surroundings exchange within themselves.

A system is said to be an isolated system if

If we want to study the liquid inside the flask, we can define A, B and C as
