Geologic time scales are essential tools for geologists and biologists alike as a result of they assist show the history of the whole world in terms of relationships between totally different plate movements.

Explanation:

Time could be an important variable in earth science, as a result of the exact timing of spatially separated events permits the United States of America to reconstruct the surface and surface conditions of the ancient earth. ... geological time spans area unit significantly more difficult to grasp than historical time spans as a result of they're therefore incredibly long.

In the geological timescale, time is usually divided on the premise of the earth's biotic composition, with the Phanerozoic aeon(i.e. the era, Mesozoic era and cenozoic Eras) representing the amount of Earth's history with advanced life forms, and therefore the Pre Cambrian (or Proterozoic and Hadean Eras.

What is the force that the gas exerts on each of the six sides of the box when the gas temperature is 20.0∘C?

Taya2010 [7]

Incomplete question as number of moles and length is missing.So I have assumed 3 moles and length of 0.300 m.So the complete question is here:

Three moles of an ideal gas are in a rigid cubical box with sides of length 0.300 m.What is the force that the gas exerts on each of the six sides of the box when the gas temperature is 20.0∘C?

Answer:

The Force act on each side is 2.43×10⁴N

Explanation:

Given data

n=3 mol

L=0.3 m

Temperature=20.0°C=293 K

To find

Force F

Solution

To get force act on each side it would employ by

F=P.A

Where P is pressure

A is Area

First we need to find pressure by applying ideal gas law

$P.V=nRT\\P=\frac{nRT}{V}\\ P=\frac{(3mol)(8.315J/mol)(293K)}{(0.3m*0.3m*0.3m)}\\P=27.069*10^{4}Pa$

So The Force is given as:

$F=P.A\\F=(27.069*10^{4} )(0.3m*0.3m)\\F=2.43*10^{4}N$

The Force act on each side is 2.43×10⁴N
