1.	Hydrogen can be fused to form helium atA. High temperature and high pressureB. high temperature and low pressureC. low temperature and high pressureD. low temperature and low pressure
Answer» Correct Answer - A A fusion reaction is difficult to occur because positively charged nuclei repel each other. At very high temperatures of the order of `10^(6)` to `10^(7)` the nuclei may have sufficient energy to overcome the repulsive forces and fuse. It is for this reason, fusion reactions are also called thermonuclear reactions. Hence, hydrogen can be fused to form helium at high temperature and high pressure.
