Fusion processes, like combining two deu...

Fusion processes, like combining two deuterons to form a `He` nucleus are impossible at ordinary temperature and pressure. The reasons for this can be traced to the fact:

A

nuclear forces have short range

B

nuclei are positively charged

C

the original nuclei must be completely ionized before fusion can take place

D

the original nuclei must first break up before combining with each other

Text Solution

Verified by Experts

The correct Answer is:
a,b
Fusion processes are impossible at ordinary temperature and pressures. The reason is nuclei are positively charged and nuclear foreces are short range strongest forces.

Radioactive disintegration is a first order reaction and its rate depends only upon the nature of nucleus and does not depend upon external factors like temperature and pressure. The rate of radioactive disintegration (Activity) is represented as -(dN)/(dt)=lambdaN Where lambda= decay constant, N= number of nuclei at time t, N_(0) =intial no. of nuclei. The above equation after integration can be represented as lambda=(2.303)/(t)log((N_(0))/(N)) Half-life period of U^(2.5xx10^(5) years. In how much thime will the amount of U^(237) remaining be only 25% of the original amount ?

Each phase of a material can exits only in certain regions of pressure and temperature . P-T phase diagrams, in which pressure is plotted versus temperature, show the regions corresponding to various phases and phase transformations . P-V diagrams, on the other hand , can be used to study pressure volume relationship at a constant temperature. If the liquid and gaseous phases of a pure substances are heated together in a closed container, both the temperature and the vapor pressure will increase until a point is reached at which the two phases can no longer be distinguished from one another. The temperature and pressure at which this occurs are called the critical temperature and pressure. Exceeding either of these parameters, by itself ,will cause the "gas"//"liguid" phase transition to disappear. if the other variable is then changed as well, while the first variable is maintained above its critical point , a gradual transition will occur between the gaseous and liquid phases, with no clear boundary.(The liquid and solid phases, on the other hand , maintain a distinct boundary at all pressure above the triple point). Shown in figure is a combined P-T phase diagram for material A and B . If heat is added to solids A and B , each in a container that is open to the atmosphere :-

Two identical soap bubbles each of radius r and of the same surface tension T combine to form a new soap bubble of radius R . The two bubbles contain air at the same temperature. If the atmospheric pressure is p_(0) then find the surface tension T of the soap solution in terms of p_(0) , r and R . Assume process is isothermal.
