Answer: Option (b) is the correct answer.

Explanation:

When gas is compressed then molecules of gas will come closer to each other. Though molecules already had kinetic energy and on compressing the molecules will collide more rapidly with each other.

As a result, energy will be released in the form of heat. Thus, there will be rise in temperature.

Hence, we can conclude that when a gas is compressed, the molecules are pushed closer together causing the gas to rise in temperature.

The answer is "rise in temperature". Think of when you're in a crowded place. When it's crowded it gets hot because of the energy radiating off of everyone around you.

Calculate the pressure the fluid exerted on your diver. The acceleration of gravity is 9.8 m/s2 and the density of the water is

Complete question:

A diver is 10 m below the surface of water. Calculate the pressure the fluid exerted on the diver. The acceleration of gravity is 9.8 m/s2 and the density of the water is 1000 kg/m3. Answer in units of Pa. Show your work.

Answer:

Tthe pressure the fluid exerted on the diver is 1.99 x 10⁵ Pa

Explanation:

Given;

density of water, ρ = 1000 kg/m³

diver's position below the surface of the water, h = 10 m

acceleration due to gravity, g = 9.8 m/s²

Let the atmospheric pressure, P₀ = 101325 Pa

The pressure 10 m below the surface of the water is calculated as;

P = P₀ + ρgh

P = 101325 Pa + (1000 x 9.8 x 10)Pa

P = 199325 Pa
