How many triple points are in the phase diagram below:
solong [7]

Answer: There are 3 triple points in the given phase diagram.

Explanation: Triple point is defined as the point at which the temperature and pressure of the 3 phases are in equilibrium with each other.

In the given phase diagram, there are three points which is satisfying this definition.

Point A: At this point The monoclinic form and rhombic form have the same vapor pressure. Hence,

Rhombic(s) \rightleftharpoons Monoclinic(s) \rightleftharpoons Vapor(g)

Point B: At this point, the monoclinic form starts to melt. Hence,

Rhombic(s) \rightleftharpoons Liquid(l) \rightleftharpoons Vapor(g)

Point C: At this point, the rhombic form, monolinic form and liquid is in equilibrium. Hence,

Rhombic(s) \rightleftharpoons Monoclinic(s) \rightleftharpoons Liquid(l)

Hence, this system has 3 triple points.

If I fill a balloon with 5.2 moles of gas and it creates a balloon with a volume of 23.5 liters, how many moles are in a balloon
patriot [66]

Answer:

n= 0.303mol

Explanation:

From PV= nRT

R= PV/nT

Comparing 2-systems of baloons

P1V1/n1T1 = P2V2/n2T2

Since pressure and temperature are constant

V1/n1= V2/n2

23.5/5.2 = 14.9/n2

Simplify

n2= 0.303mol
