Answer:

Mean

Explanation:

The mean of a series of measurements is calculated when a<em>ll the measurements are added up and then divided by the number of measurements taken</em>, as follows:

Sum of Measurements = 20.73 + 20.76 + 20.68 + 20.75 = 82.92

As<u> there are 4 measurements</u>, the mean is:

Mean = 82.92 / 4 = 20.73

Which statement describes effusion?

frez [133]

Answer:

It occurs when a gas passes through a tiny hole.

Explanation:

Effusion is a term used to describe when a gaseous molecule in a container passes or escapes through a tiny/small hole. Effusion and diffusion are two properties of gases that are often used interchangeably, however, they differ.

Effusion differs from diffusion in the sense that the gas passes through a TINY HOLE that is smaller than the normal path. This is contrary to when gas disperses throughout a container as in diffusion.

Answer:

people with breathing problems such as severe asthma.

I need help ASAP please

Andrej [43]

525L

Explanation:

Given parameters:

Volume to Temperature ratio = 1.75

Temperature = 300k

Unknown:

Volume of the gas = ?

Solution:

We must carefully analyze and comprehend the detailed description of this experiment:

It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.

This implies that the pressure in the vessel is constant

This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.

Mathematically;

$\frac{V1}{T1} = \frac{V2}{T2}$

V and T are the volume and temperature

Now we can solve the given problem;

$\frac{V}{T}$ = 1.75

Since temperature is given as 300K

Input the variables:

$\frac{V}{300}$ = 1.75

V = 1.75 x 300 = 525L

Imagine a drop of water in oil. If you add surfactant, explain how the surfactant molecules organize themselves around the water

Oduvanchick [21]

If you add a surfactant in water-oil mixture, surfactant molecules would form micelles wherein the hydrophobic end of the surfactant faces inside the micelle while the hydrophilic end faces the water molecules. Inside these micelles oil particles are attached.
