Thermodynamics ...

A thermodynamic system goes from states (i) P₁ V to 2P₁, V (ii) P, V₁ to P, 2V₁. Then, work done in the two cases is

If R = Universal gas constant, the amount of heat needed to raise the temperature of 2 moles of an ideal monoatomic gas from 273 K to 373 K when no work is done

A system performs work ∆W when an amount of heat is ∆Q added to the system, the corresponding change in the internal energy is ∆U. A unique function of the initial and final states (irrespective of the mode of change) is

When the amount of work done is 333 cal and change in internal energy is 167 cal, then the heat supplied is

First law of thermodynamics states that

A thermo-dynamical system is changed from state (P₁, V₁) to (P₂, V₂) by two different process. The quantity which will remain same will be

Which of the following statement is true?

A perfect gas contained in a cylinder is kept in vacuum. If the cylinder suddenly bursts, then the temperature of the gas

If ∆Q and ∆W represent the heat supplied to the system and the work done on the system respectively, then the first law of thermodynamics can be written as

In a given process for an ideal gas, dW = 0 and DQ < 0. Then, for the gas
