The density of a liquid is to be determined by an old 1-cm- diameter cylindrical hydrometer whose division marks are completely wiped out. The hydrometer is first dropped in water, and the water level is marked. The hydrometer is then dropped into the other liquid, and it is observed that the mark for water has risen S cm above the liquid-air interface. If the height of the original water mark is 12.7 cm, determine the density of the liquid. Mark for water S cm Unknown 12 cm liquid S (cm) 0.85

Hydrogen Energy

Energy is a quantity that cannot be defined, its existence can only be felt. In simple language, if a system possesses energy, it can do a specific kind of work. There are many forms of energy sources which people can use to obtain work. Solar energy, tidal energy, hydroelectric energy, geothermal energy, wind energy are some of the renewable energy sources which are primarily used for the production of electricity.
