Answer:

SEE BELOW

Explanation:

Given   500 cm^3 = V1    760 mm = P1     (760*2) = P2

Required   V2

P1V1 = P2V2

RE-ARRANGE  TO    P1V1/P2 = V2

(760)(500) /(760*2) = V2

V2 = 250 ML

According to Boyles law

\\ \rm\Rrightarrow P\propto \dfrac{1}{v}

  • So if pressure is increased volume will be decreased and vice versa

Now pressure is doubled means multiplied by 2

The volume will be divided by two of get halved .

New volume

  • 500/2
  • 250cm³

Answer:

1. Main sequence stars have different masses. The common characteristic they have is their source of energy. They burn fuel in their core through the process of fusing hydrogen atoms into helium.

2. Supergiants are among the most massive and most luminous stars. Supergiant stars occupy the top region of the Hertzsprung–Russell diagram with absolute visual magnitudes between about −3 and −8. The temperature range of supergiant stars spans from about 3,400 K to over 20,000 K.

3. Supergiants develop when massive main-sequence stars run out of hydrogen in their cores.

4. a supernova occur When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion.

5. when a star has reached the end of its life and explodes in a brilliant burst of light
