- Suppose a small sample of pure X is held at -26.°C and 21.3 atm. What will be the state of the sample (solid, liquid, or gas)? - Suppose the temperature is held constant at -26.°C but the pressure is decreased by 15.7 atm. What will happen to the sample (nothing, it will melt, it will freeze, it will boil, it will condense, it will sublime, or it will deposit)? - Suppose, on the other hand, the pressure is held constant at 21.3 atm but the temperature is increased by 83.°C. What will happen to the sample(nothing, it will melt, it will freeze, it will boil, it will condense, it will sublime, or it will deposit)? - This is all part one question
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.
