Two lithium nuclei in a lithium vapour at room temperature do not combine to form a carbon nucleus because

(a) At room temperature (25 °C), water is a liquid because it has the following characteristic of liquid: (i). At room temperature, water has no shape but has a fixed volume...

We can see any object, when light reflected by that object reaches our eyes. But in the dark room, no light is reflected by the object so we are unable...

Let us denote 2 boys and 2 girls in room X as B1, B2 and G1, G2 respectively. Let us denote 1 boy and 3 girls in room Y as...

(C) carbon dioxide only

(a) : Statement-1 states that energy is released when heavy nuclei undergo fission and light nuclei undergo fusion is correct. Statement-2 is wrong The binding energy per nucleon, B/A, starts at...

(d) :- After decay, the daughter nuclei will be more stable, hence binding energy per nucleon of daughter nuclei is more than that of their parent nucleus. Hence, E2 > E1

(c) At higher temperatures, dinitrogen combines with metals to form ionic nitrides.

Temp = 20°C        Dew point = 10°C The place is saturated at 10°C Even if the temp drop dew point remains unaffected. The air has V.P. which is the saturation VP...

(C) totally different from both carbon and oxygen
