As the sizes of elements belonging to group 14 are smaller than the corresponding elements of group 13, their first ionization energies are higher than those of corresponding members of group 13. Among the members of the same group, the ionization energies (IE) follow the order..

Judicious use of Energy - In order to live and enable ourselves to do everyday work we need energy. The prosperity of a country depends upon the availability of energy. Huge amount of electrical energy is used to run the air conditioners, cold storage and oth..

Lydia had more than $105 in her savings account. She withdrew $68 from her savings account. Which of the following inequalities best suits the balance amount m , in her savings account? => m > 37 or m < 37 or m ≤ 37 or m &ge; 37..

In metals, the conduction band and valence band partly overlap each other and there is no forbidden energy gap. In insulators, the conduction band is empty and valence band is completely filled and forbidden gap is quite large = 6 eV. No electron from valence band can cross over to c..

The stocks of fuels are limited and hence use of energy saving devices is a must. As far as possible use only renewable sources of energy. More efficient heating installations should be employed while cooking. Incomplete combustion of fuel results in wastage of fuel le..

Growing consumption and non renewablity fossil fuel necessitate the conservation of this natural resource of to help in this effort many measures have been advocated. 1) Use of oil should be minimized so as to save it for future use. Public transport should be used as far possible. 2) Mo..

is a natural gas. It is produced from animal, water and weeds and other plants. India comes first in developing and using biogas technology. It is cheap, non-polluting and labour-saving fuel. Biogas can be used for cooking, lighting, and in vehicles. Solar energy, wind en..

Question: Explain the three R's in the conservation of environment? Answer: The three R's refer to Reduce, Recycle and Reuse. Reduce: Use less electricity by switching off unnecessary lights and fans, save water by repairing leaky taps, do not waste food. Recycle: Materials mad..

A remarkable property of carbon is its ability to form compounds in which carbon atoms are linked to one another in chains or rings. This property of forming chains of identical atoms is called catenation. The property of catenation depends upon the strength of atom-atom bond. The greater the stre..

>Following are some examples, which indicate how natural resources could be protected. i) Promotion and use of non-conventional sources of energy like solar energy. ii) Promotion and development of mint - hydro projects so that resources are better utilized. iii) All types of po..
