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.
At a pressure of 1 atm, the temperature 54.8 K is called the fill in the blank 1 of O2.

O2 is a _________at 1.50×10-3 atm and 100 K.
![This graph represents the phase diagram of nitrogen, illustrating the relationship between pressure (P, in atmospheres) and temperature (T, in Kelvin).
- The x-axis (horizontal) is labeled "T Kelvin," covering temperatures from approximately 54.4 K to 154.6 K.
- The y-axis (vertical) is labeled "P atm," with pressures ranging from 0.00150 atm to 49.8 atm.
The curve on the graph shows a nonlinear relationship between temperature and pressure. As the temperature increases, the pressure also increases, indicating the conditions under which nitrogen changes phases (e.g., from solid to liquid or gas).
The line intersects the y-axis near 0.00150 atm and gradually curves upwards, becoming steeper as it approaches higher temperatures and pressures. The graph provides reference lines at specific values on both axes for better clarity of changes at those points.
This visualization helps in understanding the critical points at which nitrogen shifts between different states of matter under varying temperature and pressure conditions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F26ce9fac-5496-44dc-927a-9e7aad74d43b%2Fe19016fa-f4b0-4aa1-97f4-faee6a6c2b86%2F9mpkrxm_processed.gif&w=3840&q=75)
