Substance Xis known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperatuire. Additionally, the values of these other properties of X have been deteomined: melung point 20. C boiling point 55.°C enthisipy of fusion 9.00 kmol enthalpy of vaporization 44,00 kl/mol 1.70 g/em (solid) L40 gml (iouuid) density 36. JKmol (solid) heat capacity 63 JKmol (liquid) 47. JKmol (vapor) You may also assume X behaves as an ideal gas in the vapor phase Suppose a small sample of X at 0 C is put into an evacuate flask and heated at a constant rate until 6.0 kl mol of heat has been added to the sample, Graph the temperature of the sample that would be observed duning this experiment.
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.
