Imagine a substance with the following points on the phase diagram: a triple point at .5 atm and -5°C; a normal melting point at 20°C; a normal boiling point at 150°C; and a critical point at 5 atm and 1000°C. The solid- liquid line is "normal" (meaning positive sloping). For this, complete the following: 1. Roughly sketch the phase diagram, using units of atmosphere and Kelvin. 1-solid, 2-liquid, 3-gas, 4-supercritical fluid, point O-triple point, C-critical point -78.5 °C (The phase of dry ice changes from solid to gas at -78.5 °C) 2. Rank the states with respect to increasing density and increasing energy. 3. Describe what one would see at pressures and temperatures above 5 atm and 1000°C.

Concept explainers

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Question

Problems
Imagine a substance with the following
points on the phase diagram: a triple point at
.5 atm and -5°C; a normal melting point at
20°C; a normal boiling point at 150°C; and a
critical point at 5 atm and 1000°C. The solid-
liquid line is "normal" (meaning positive
sloping). For this, complete the following:
1. Roughly sketch the phase diagram, using
units of atmosphere and Kelvin.
1-solid, 2-liquid, 3-gas, 4-supercritical fluid,
point O-triple point, C-critical point -78.5 °C

gas at -78.5 °C)
2. Rank the states with respect to increasing
density and increasing energy.
3. Describe what one would see at pressures
and temperatures above 5 atm and 1000°C.
