1meter/10 milimeters which should be 1000 mm

1m=1000mm

<span>International System of Units (SI Units) are organized body of measurements for physical quantity. They are set to be the norm or global norm scaling for every physical quantity which includes kilogram, meter, second, ampere, kelvin, candela and mole. These measurements then can increase or decrease by the power of ten, multiplied or divided. As said and explained, the SI is helpful in describing objects because </span>
<span><span>1.       </span>They give us the idea of how much matter is contained in that single substance or the current state the matter is in or how hot or cold. We measure and can quantify the quality of the specific matter.</span> <span><span>
2.       </span>SI Units are a global set of measurement hence, we can communicate with ease from western to eastern countries with these measurements without having problems in terms of portraying or displaying a set of physical quantities.</span>

3. Why do gases deviate from the ideal gas law at high pressures? A. Molecules have finite volume. B. Cohesive forces increase t
ipn [44]

Answer:

A. Molecules have finite volume.

Explanation:

Gases deviate from the ideal gas law at high pressures because its molecules have a finite volume.

Real gases have a finite volume which enables more interaction between the molecules while ideal gases are assumed not to have a finite volume or occupy space which is why it lacks any form of interaction between its molecules.

This difference is the deviation between the real and ideal gases.

What property of gas molecule affects the speed at which it diffuses?
Tresset [83]

Answer:

Helium and Ethlyene Oxide. Your answer is MASS.

Explanation:

Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. effusion refers to the movement of gas particles through a small hole. Graham's law state's that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.

just olya [345]

The pressure of the gas = 40 atm

<h3>Further explanation</h3>

Given

200 ml container

P = 2 atm

final volume = 10 ml

Required

Final pressure

Solution

Boyle's Law  

At a fixed temperature, the gas volume is inversely proportional to the pressure applied  

\tt \rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}

Input the value :

P₂ = P₁V₁/V₂

P₂ = 2 x 200 / 10

P₂ = 40 atm
