The final temperature and pressure in a container is 234K at 210 kPa.
If initial temperature was 175 K, what was the starting pressure?

Answers

Answer:

Initial pressure = 157 kpa (Approx)

Explanation:

Given:

final temperature = 234 K

final pressure = 210 kpa

Initial temperature = 175 K

Find:

Initial pressure

Computation:

Initial pressure / Initial temperature = final pressure / final temperature

Initial pressure / 175 = 210 / 234

Initial pressure = 157 kpa (Approx)

Why do we use Scientific Notation?

Answers

Answer:

Scientific Notation was developed in order to easily represent numbers that are either very large or very small.  As you can see, it could get tedious writing out those numbers repeatedly. So, a system was developed to help represent these numbers in a way that was easy to read and understand: Scientific Notation.

Explanation:

Answer:

Working with very large or small quantities usually ends up being quite complicated. Scientific notation is a way to write numbers in an abbreviated way, making it easier to work with these numbers.

Explanation:

Aly's science class was looking at bacteria through a microscope. Aly's teacher said some bacteria can be as small as 0.00365 cm long. What is the length of the bacteria written in scientific notation?

Answers

Answer:

[tex]0.00365\ cm=3.65\times 10^{-3}\ cm[/tex]

Explanation:

Aly's teacher said some bacteria can be as small as 0.00365 cm long.

In this problem, we need to write the length of the bacteria written in scientific notation. Any number can be written in the form of scientific notation as follows :

[tex]N=a\times 10^b[/tex]

a is a real no and b is an integer

In the given number, there are two zeroes before 3. We need to shift the decimal after 3. It can be done as follows :

[tex]0.00365\ cm=3.65\times 10^{-3}\ cm[/tex]

Hence, this is the required solution.

2. An all natural mosquito repellent

is trying to make its way into the

market. One arm is sprayed with the

repellent and one arm is not sprayed

with anything. After 3 hours, the

number of mosquito bites is counted. What is the control group

Answers

Answer:

The arm that was not sprayed with anything

Explanation:

The control group would be the arm that was not sprayed with anything.

The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.

12. If the particles of a liquid are always moving, why don't they all come apart from each other and become a gas?​

Answers

Answer:

even though the particles of a liquid are moving, they are attracted to each other so they don't spread far apart to become a gas.

Explanation:

"but some do when they evaporate"

In liquids, the particles are allowed to move freely rather than the solid. The gaseous particles can move more freely than liquids.

Particles in liquids:

In liquids, the particles are placed randomly and thus are allowed to move freely but they do not become a gas as liquids are slightly less compressible than gases.  Even though the particles of a liquid are moving, they are attracted to each other so they don't just spread far apart to become a gas.

What are ionic compounds?

The crystalline solids which are formed by closely packed ions of opposite charge are called ionic compounds. In ionic compounds, the ions are connected with each other by ionic bonds in solis state.

The elements which can gain or lose electrons to attain their nearest noble gas configuration participate in the formation of ionic compounds. The solid ionic compound cannot able to conduct electricity.

In the melted state, the ions of K⁺ and Br⁻ can move from their fixed positions. Therefore, the KBr can conduct electricity when melted or dissolved in water.

The ionic compounds are able to conduct electricity in melted or dissolved in water. Because only in these states the ins can move freely while in the crystalline state the ions cannot move freely to conduct electricity.

Which characteristic is related to kinetic energy but not potential energy

Answers

Answer:

kinectic is movement and potential is still

Explanation:

While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment. Hence the acceleration of an object is not evident in the movement of one object, where other objects in the same environment are also in motion.

As you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What two processes did you observe?

Answers

Answer:

Weathering and erosion

Explanation:

Weathering can be explained as the breaking down of rocks/minerals on the surface of the Earth as a result of contact with biological organism, water, air and other factors

. There are 3 common types of weathering which are;

1) physical weathering

2) biological weathering

3) chemical weathering

Erosion can be regarded as a geological process, whereby earthen material are been transported away by natural forces, these forces could be wind as well as water.

Therefore, as you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What is observed are weathering and erosion processes.

After the weakening and broken up of the rock by weathering then erosion transport the bit of the rock down the mountain as you are climbing, which means the "weathering process" breakdown and the "erosion process" involves the transport or movement of the bit of the rocks

Electromagnetic waves will travel the SAME SPEED (speed of light) WITHIN a medium as it does WITHOUT a medium. Question options: True False

Answers

Answer:

True

Explanation:

The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.

Electromagnetic waves are waves that do not require a material medium for their propagation. They are able to pass through vacuums and mediums with particles at constant speed. It is mechanical waves whose speed is medium dependent. Mechanical waves have varying speed based on the mediums they move through.
