Which type of star has the lowest density?
a. giant
b. white dwarf
c. neutron
d. main sequence

A. giant

Explanation:

Giant stars are older and hotter than dwarf stars. They can be thousands of times brighter than our Sun. They have low density (although they are large) as opposed to the white dwarf which is one of the celestial bodies with the highest density.

Among the giant stars we can mention the red giants and the blue giants.

The end of the lives of these stars is marked by explosive cosmic events, such as supernovae, which can give rise to black holes.

its not a choice. you dont choose if you want to be gay or straight.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
