The spontaneity means, having the potential to proceed without the assistance of external agency. The processes which occur spontaneously are

A

flow of heat from colder to warmer body

B

gas in a container contracting into one corner.

C

gas expanding to fill the available volume

D

burning carbon in oxygen to give carbon dioxide.

Text Solution

Verified by Experts

The correct Answer is:
C, D
Options (A) and (B) can neither occur by themselves nor by initiation, (C) can occur by itself, (D) occur on initiation.
Flowing of heat from warmer to colder body, expanding of gas and burning of carbon to give carbon dioxide, all are spontaneous process.

A swimmer swins in still water at a speed =5 km//hr . He enters a 200m wide river, having river flow speed =4km//hr at point A and proceeds to swim at an angle of 127^(@) (sin 37^(@) = 0.6) with the river flow direction. Another point B is located directly across A on the other side. the swimmer lands on the other bank at a point C , form which he walks the distance CB with a speed = 3km//hr . The total time in which he reaces from A to B is

Hanumappa and his wif Gangamma are busy making jaggery out of sugarcane juice. They have processed the sugrcane juice to make the molasses, which is poured into moulds in the shape of a frustum of a cone having the diameters of its two circular faces as 30 cm and 35 cm and the vertical height of the mould is 14 cm (see the give figure). If each cm^(3) of molasses has mass about n 1.2g find the mass of the molasses that can be poured into each mould, (Take pi =(22)/(7))

Consider the decay of a free neutron at rest : n to p +e^(-) Show that the two body decay of this type must necessary give an electron of fixed energy and therefore cannot account distribution in the beta - decay of a neutron or a nucleous as shown in figure . [ Note : The simple result of this exercise was one among the several arguments advanced by W . Pauli to perdict the existence of a third particle in the decay products of beta - decay . This particle is known as neutrino spin 1/2 ( like e^(-) p or n ) but is neutral ad either massless or having an extremely small mass (compared to the mass of electron) and which interacts very weakly with matter . The correct decay process of neutron is : n to p+e(-)+v)

The ciliary muscles of eye control the curvature of the lens in the eye and hence can alter the effective focal length of the system. When the muscles are fully relaxed, the focal length is maximum. When the muscles are strained, the curvature of lens increases. That means radius of curvature decreases and focal length decreases. For a clear vision, the image must be on the retina. The image distance is therefore fixed for clear vision and it equals the distance of retina from eye lens. It is about 2.5cm for a grown up person. A perosn can theoretically have clear vision of an object situated at any large distance from the eye. The smallest distance at which a person can clearly see is related to minimum possible focal length. The ciliary muscles are most strained in this position. For an average grown up person, minimum distance of the object should be around 25cm. A person suffering from eye defects uses spectacles (eye glass). The function of lens of spectacles is to form the image of the objects within the range in which the person can see clearly. The image o the spectacle lens becomes object for the eye lens and whose image is formed on the retina. The number of spectacle lens used for th eremedy of eye defect is decided by the power fo the lens required and the number of spectacle lens is equal to the numerical value of the power of lens with sign. For example, if power of the lens required is +3D (converging lens of focal length 100//3cm ), then number of lens will be +3 . For all the calculations required, you can use the lens formula and lensmaker's formula. Assume that the eye lens is equiconvex lens. Neglect the distance between the eye lens and the spectacle lens. Q. Maximum focal length of a eye lens of a normal person is
