the following graph represents a tool that astronomers use to classify stars - the hr diagram. analyze the graph to answer the questions. 1. what is the independent variable? 2. what is the dependent variable? 3. what are two conclusions you can draw from the information presented? a) ________ b) ________ 4. what would \kelvin\ be possibly referring to? b) size of star b) unit for temperature

Answer

Brief Explanations:

  1. In an HR - Diagram, temperature is typically the independent variable as it is not affected by other factors in the context of the diagram.
  2. Luminosity is the dependent variable as it depends on the temperature and other properties of the star.
  3. a) Most stars lie on the main - sequence, which shows a relationship between temperature and luminosity. b) Giants and super - giants are larger and more luminous than main - sequence stars of the same temperature.
  4. Kelvin is the SI unit for temperature.

Answer:

  1. Temperature
  2. Luminosity
  3. a) Most stars are on the main sequence. b) Giants and super - giants are more luminous than main - sequence stars of the same temperature.
  4. b) Unit for temperature
