On the star maps, the constellation names are in upper case letters and bright stars that have proper names are printed in lower case letters. on the summer star map, look for the stars marked deneb, vega and altair. these stars lie in the constellations cygnus, lyra and aquila respectively. if you connect these stars, you can see the "summer triangle" they form. 2. which star, deneb, vega or altair will be closest to the zenith (almost overhead) at the time noted on the summer star map? a. deneb b. vega c. altair d. they will all be overhead.\

b. Vega

Explanation:

Vega would be the star that is closest to the zenith on the summer star map. Vega is the brightest star in the constellation of Lyra. Its age is about a tenth of the sun. However, as the expected lifetime of the star is also a tenth of that of the sun (due to its larger size), both stars are at a similar point in their life expectancies. Vega is one of the most studied stars, as it is one of the closest stars to Earth and thus one of the brightest. Vega was also the Northern pole star around 12,000 BCE.

the clapeyron equation (also called the clausius-clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.
