Which graph correctly shows the relationship between temperature and kinetic energy in one phase of matter?

1 answer

In general, the relationship between temperature and kinetic energy in any phase of matter can be illustrated with a simple graph. The kinetic energy of the particles in a substance is directly proportional to its temperature. As temperature increases, the kinetic energy of the particles also increases.

Illustration:

  1. Graph Layout:

    • X-axis: Temperature (in degrees Celsius, Kelvin, or another appropriate scale)
    • Y-axis: Kinetic Energy (in joules or another appropriate unit)
  2. Graph Shape:

    • The graph would be a straight line that slopes upward to the right. This indicates that as temperature increases, kinetic energy also increases.
  3. Labeling:

    • Ensure both axes are clearly labeled with units.
    • Add a title such as "Relationship between Temperature and Kinetic Energy in a Phase of Matter".

Graph Description:

  • At low temperatures, the kinetic energy is low, and as you move to the right (higher temperatures), the kinetic energy rises in a linear fashion.
  • You might include a specific point or range indicating the typical temperatures for a given phase of matter (solid, liquid, or gas) to provide context on how kinetic energy varies with temperature in that specific phase.

Example:

      Kinetic Energy
         |
         |           /
         |         /
         |       /
         |     /
         |   /
         | /
         +----------------- Temperature

Note: The slope of the line indicates the direct relationship. The actual appearance can vary slightly based on the scale and context, but the general proportionality (a straight line) holds true across different phases of matter, reflecting that kinetic energy is proportional to temperature.
