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

**Title: Vapor Pressure of Four Liquids**

**Graph Description**

The graph illustrates the vapor pressure of four different liquids as a function of temperature. The x-axis represents temperature in degrees Celsius (°C), ranging from 0 to 125°C. The y-axis represents vapor pressure in kilopascals (kPa), ranging from 0 to 200 kPa.

**Liquids Plotted:**

1. **Propanone**: This curve is positioned at the leftmost part of the graph, indicating it has the highest vapor pressure at any given temperature compared to the other liquids.

2. **Ethanol**: This curve is to the right of propanone, with a lower vapor pressure at comparable temperatures.

3. **Water**: The water curve is positioned further to the right, indicating a lower vapor pressure than both propanone and ethanol at similar temperatures.

4. **Ethanoic Acid**: This is the rightmost curve, with the lowest vapor pressure of the four liquids at comparable temperatures.

**Key Feature:**

- A horizontal dashed line is drawn across the graph at 101.3 kPa, representing standard atmospheric pressure.

**Application:**

This graph can be used to determine the boiling points of the liquids at standard atmospheric pressure (101.3 kPa). The temperature at which each curve intersects the dashed line corresponds to the boiling point of that liquid under normal atmospheric conditions.

**Study Notes:**

- Propanone has the lowest boiling point of the four liquids.
- Ethanoic acid has the highest boiling point.
- Understanding these curves helps in studying the volatility and evaporation rates of different substances.

This educational resource is intended to support learning about phase changes and the relationship between temperature and vapor pressure in various liquids.

O The molecules with low kinetic energy are the first to evaporate. O The molecules with high kinetic energy are the first to evaporate. O As the temperature increases, the average kinetic energy of the molecules increases. O As the temperature increases, a larger fraction of the molecules have sufficient energy to escape from the liquid. O As the temperature increases, a smaller fraction of the molecules have sufficient energy to escape from the liquid.
