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.

**3. Use the diagram to answer the following:**
A graph is shown with the x-axis labeled "Energy" and the y-axis labeled "Temperature." The graph has several marked points:
- A to B: Solid
- C: Solid → Liquid (melting point)
- D to E: Liquid
- E: Liquid → Gas (boiling point)
- F: Condensation begins
- G: Gas
**a. Identify the point of the graph where each of the following occurs:**
i. Melting begins: **C**
ii. Boiling begins: **E**
iii. Freezing begins: **D (assuming it's not explicitly marked)**
iv. Condensation begins: **F**
**b. Suppose you have 10 grams of water at 25°C. What do you need to do to get the 10 grams of water to point C?**
To move the 10 grams of water to point C, you must cool the water to the melting point where it transitions from liquid to solid.
**4. Using the phase diagram to the right:**
A small phase diagram is shown with a curve and labeled axes:
- x-axis: Temperature (T Kelvin)
- y-axis: Pressure (P atm)
**a. Label each phase in the diagram to the right in the box provided.**
- A: Solid
- B: Liquid
- C: Gas
**b. What is the normal melting and normal boiling points?**
- Normal melting point is approximately at 54.4 Kelvin.
- Normal boiling point is approximately at 90.2 Kelvin.
**c. What is the phase change associated with letter A when the pressure is suddenly dropped?**
When the pressure is suddenly dropped at point A, the phase change is from solid to gas (sublimation).
These diagrams and questions are designed to help understand the changes in states of matter with respect to energy, temperature, and pressure conditions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6c605e87-2c96-4aa2-99a1-2c5d12ea3556%2F3412e790-7658-4c89-851f-0a6b0df50728%2Fu8nicnh_processed.jpeg&w=3840&q=75)
