What is a H-R diagram and what two characteristics of stars are compared on it?
It is a diagram on which stars are plotted according to their absolute magnitudes (or luminosities) against their stellar classifications (or effective temperatures).
What two star characteristics does Hertzsprung Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
How many dots are shown in the eletctron dot diagram for calcium?
In an electron dot diagram for calcium, there are two dots shown. Calcium has two valence electrons, which are represented by the dots placed around the symbol "Ca" in the diagram. These dots are typically placed on the sides of the element's symbol to indicate the electrons available for bonding.
What is a red gigant?
One of two groups of stars on the Hertzsprung -Russell diagram that have a different set of properties than the main sequence stars; bright, low-temperature giant stars that are enormously bright for their temperature.
How are the conditions of pressure and temperature at which two phases coexist in equilibrium shown on a phase diagram?
By a line separating the phases
What two characteristics of stars are shown in the H-R diagram?
The Hertzsprung Russell diagram plots each star as a point on the diagram, with absolute magnitude along the vertical scale and surface temperature along the horizontal scale.
What is a H-R diagram and what two characteristics of stars are compared on it?
It is a diagram on which stars are plotted according to their absolute magnitudes (or luminosities) against their stellar classifications (or effective temperatures).
What two caracteristics of a star are plotted on the Hertzsprung Russell diagram?
Brightness and Temperature are the two characteristics plotted on the H-R diagram a diagram used to plot the absolute magnitude of stars and their temperatures
What two caracteristics of a star are plotted on the Hertzsprung-Russell diagram?
The two characteristics of a star plotted on the Hertzsprung-Russell diagram are luminosity (brightness) on the y-axis and temperature or spectral type on the x-axis. This diagram helps astronomers classify stars according to their different stages of evolution.
What two star characteristics does the hertzsprung - Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
What two star characteristics does Hertzsprung Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
How many dots are shown for in the electron dot diagram for calcium?
In the electron dot diagram for calcium, there are two dots shown, as calcium has two valence electrons.
2. The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
Does An HR diagram plots a stars luminosity and surface temperature?
Yes, an HR diagram plots a star's luminosity (brightness) against its surface temperature, also known as color or spectral type. This graph shows the relationship between these two characteristics for different stars, allowing astronomers to classify and study them.
The two types of stars that do not fall into the main sequence of an H-R diagram are?
The two types of stars that do not fall into the main sequence of an H-R diagram are white dwarfs and giant stars. White dwarfs are small, hot stars that have exhausted their nuclear fuel, while giant stars are large, luminous stars that have evolved off the main sequence due to changes in their internal structure.
How are the conditions pressure and temperature at which two phases coexist in equilibrium shown on a phase diagram?
By a line separating the phases
