Answer:

The pressure the hydrogen gas exerted before its volume was decreased is 2.7207 atm.

Explanation:

Using Boyle's law

{P_1}\times {V_1}={P_2}\times {V_2}

Given ,  

V₁ = 14.65 L

V₂ = 7.94 L

P₁ = ?

P₂ = 5.02 atm

Using above equation as:

{P_1}\times {V_1}={P_2}\times {V_2}

{P_1}\times {14.65}={5.02}\times {7.94}\ atm

{P_1}=\frac {{5.02}\times {7.94}}{14.65}\ atm

{P_1}=2.7207\ atm

<u>The pressure the hydrogen gas exerted before its volume was decreased is 2.7207 atm.</u>

What is kinetic theory
Eddi Din [679]

The kinetic theory of gases describes a gas as a large number of submicroscopic particles, all of which are in constant, rapid, random motion. The randomness arises from the particles' many collisions with each other and with the walls of the container.

valentina_108 [34]

Answer:

100,000,000,000

Explanation:

Given that :

1 hubble space telescope pointed at 1 section of the sky reveals 10,000 distinct galaxies ;

Number of sections from which observation is to be made = 10,000,000

Number of distinct galaxy per section = 10,000

Number of galaxies that would exist in the known universe :

Total number of galaxies in the known universe :

Number of galaxies per section * number of sections

10,000 * 10,000,000

= 100,000,000,000s
