Answer 1

Answer:

you can also see the difference between a two and one of those

Answer 2

Option C) With increase in pressure transition temperature decreases.

• The attraction forces that act over a 180° solid angle at a liquid's surface control the vapour pressure of that substance. There are less nearest-neighbor attractions experienced by each molecule in a very small drop than there are in the bulk of the liquid due to the curvature of the liquid surface.
• The drop has a higher vapour pressure than the bulk liquid because the outermost molecules of the liquid are less securely bonded to it. The drop will evaporate if its vapour pressure is higher than the partial pressure of vapour in the gas phase. Therefore, it is extremely unlikely that a vapour will ever condense into a droplet as it cools.
• One or more substances that are totally cut off from their environment may make up a system. Its constituents are only allowed to interact with one another and are subject to changes in composition, temperature, pressure, or volume.
• The bare minimal set of independently changeable elements, such as temperature, pressure, and composition, is needed to fully define the system (without disturbing the number of phases in equilibrium). Zero, one, two, and three degree of freedom systems are referred to as invariant, uni-variant, bi-variant, and tri-variant, respectively.
• This curve, also known as the freezing point curve or the fusion curve, shows how the temperature at which water freezes (or ice melts) changes with pressure. This curve illustrates how the two phases live in equilibrium by dividing solid ice from liquid water. The OC curve originates at triple point O and ends at very high pressure C.
