Explain how different states of matter are distinguished from each other and how pure substance distinguish from mixtures

Physics

iVinArrow [24]4 years ago

Hello

The difference between the states of matter is explained as follows:
- a solid has a definite shape and a definite volume
- a liquid has a definite volume, but its shape changes depending on its container
- a gas does not have neither a definite volume nor a definite shape: both change depending on the container. In fact, a gas expands until it occupies the whole volume available.

The difference between a pure substance and a mixture is:
- a pure substance has a precise and definite chemical composition
- a mixture, instead, is a combination of two or more substances.

What is the momentum of an animal with a mass of 72kg who is moving with a velocity of 2.2 m/s
ludmilkaskok [199]

Answer:

The answer is

<h2>158.4 kgm/s</h2>

Explanation:

The momentum of an object when given it's mass and velocity can be found by using the formula

<h3>momentum = velocity × mass</h3>

From the question

velocity = 2.2 m/s

mass = 72 kg

The momentum is

momentum = 2.2 × 72

We have the final answer as

<h3>158.4 kgm/s</h3>

Hope this helps you

A ship
Juli2301 [7.4K]

Answer:

<em>The sea bed is 1125 m deep.</em>

Explanation:

<u>Speed</u>

It's the rate of change of the distance (d) traveled by an object over time (t).

The speed can be calculated by the formula:

\displaystyle v=\frac{d}{t}

It's known the speed of sound in water is v=1500 m/s. A sound wave is sent to the sea bed and bounces back to the ship 1.5 seconds later.

That is the time the wave takes to travel twice the distance from the ship to the sea bed, thus the required distance uses half of that time or t=1.5/2 = 0.75 seconds.

Solving the equation for d:

d = v.t

d = 1500 m/s * 0.75 s

d = 1125 m

The sea bed is 1125 m deep.
