The pressure-volume of varius thermodynamic processes is shown in graphs:

Work is the mole of transference of energy. It has been observed that reversible work done by the system is the maximum obtainable work

The works of isothermal and adiabatic processes are different from each other



If and are work done in isothermal, adiabatic, isobaric, and isochoric reversible processes, respectively then the correct sequence (for expansion) would be

The nerve like modified muscle in the right auricle is known as

 Process represents

A: Excess amount of CO, in air is responsible for greenhouse effect.
R: CO₂ is largely produced in respiratory functions.

If a,b,c are in A.P the  are in

If θ is one of the acute angles in a triangle, then the sine of theta is the ratio of the opposite side to the hypotenuse, the cosine is the ratio of the adjacent side to the hypotenuse, and the tangent is the ratio of the opposite side to the adjacent side.

Systemic heart refers to

Which is a analgesic drug

Penicillin was discovered by -

If  then

All three sides are equal. All three angles are congruent and are equal to 60 degrees. It is a regular polygon with three sides. The perpendicular drawn from vertex of the equilateral triangle to the opposite side bisects it into equal halves.

Two bodies of mass 1 kg and 3 kg have position vector    respectively the center of mass of this system has a position vector.

In 

In HCl macule the separation between the nuclei of the two atoms is about The approximate location of the center of mass of the molecule is - -A,i with respect of Hydrogen atom ( mass of  is 35.5 times of mass of Hydrogen)

Concrete is produced from a mixture of cement, water and small stones. Small amount of gypsum, is added in cement production to improve the subsequent hardening of concrete. The elevated temperature during the production of cement may lead to the formation of unwanted hemihydrate
