Solution
The correct option is A Water
Water can exsists in all the three forms. At the triple point
of a substance, all three phases of the substance exist in thermodynamic
equilibrium. Triple point of water is 0.01 degrees Celsius (273.16 K) and
611.56 Pa. At this temperature, water is actively changing phases from
solid to liquid to gas and vice versa. Liquid molecules and lose a little bit
of energy and solidify whereas ice and gain a little bit of energy and melt.
You can observe this when ice is melting, where both ice and water exist at the
same time.
