Compare and contrast the apparent magnitude with the absolute magnitude of a star

The apparent magnitude of an object only tells us how bright an object appears from Earth while the absolute magnitude is the apparent brightness of a star if it were viewed from a distance of 32.6 light-years

The apparent magnitude of an object only tells us how bright an object appears from Earth. Alternatively, if we know the distance and the apparent magnitude of a star, we can calculate its absolute magnitude. There are three factors which control the apparent brightness of a star as seen from Earth which are how big it is, how hot it is, and how far away it is. The absolute magnitude is a measure of the star's luminosity or the total amount of energy radiated by the star every second.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
