Answers
Answer:
V₂ = 8.8 L
Explanation:
Given data:
Initial volume = 8.5 L
Initial temperature = 294 K
Final temperature = 305 K
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 8.5 L × 305 K / 294 k
V₂ = 2592.5 L.K / 294 K
V₂ = 8.8 L

3. How is the transfer of energy different in electromagnetic waves
compared to mechanical waves?
Answers
Answer:
Electromagnetic waves are produced by the vibration of charged particles. ... A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave.

A. gas
B. solid

Answers
Answer:
a solid

because because gas would excerpt forced throughout the whole container and plasma would be too hot for the plastic container and liquid would flow throughout the container touching the sides and solid is the only one that would probably only touch the bottom of the plastic container exerting force through there

Under the right conditions, sodium (Na) and chlorine (Cl) can chemically combine to form sodium chlorine. Which of the following best explains how sodium and chlorine are able to create sodium chlorine?
A: sodium and chlorine exchange neutrons between eachother when they combine
B: electrons are transferred between sodium and chlorine when they combine
C: extra protons are created when both sodium and chlorine combine
D: The nucleus of both sodium and chlorine combined together
Answers
Answer:
I am pretty sure the answer is B
Explanation:
When atoms combine, it’s usually through the transfer or sharing of valance electrons. Valance electrons are the electrons in the outermost shell of an atom. These electrons can be given away or shared to combine with other atoms. In this particular case with sodium and chlorine, sodium gives away a valance electron to chlorine.

.) Which statement is true? (A) At a given temperature, the temperature value is a measure of the total kinetic energy of all the molecules. (B) At a given temperature, all the particles have the same amount of kinetic energy. (C) At a given temperature, the average kinetic energy of the molecules is constantly changing. (D) At a given temperature, the temperature value is a measure of the average kinetic energy of all the molecules.
Answers
Answer:
(D) At a given temperature, the temperature value is a measure of the average kinetic energy of all the molecules.
Explanation:
Kinetic energy is defined as the energy of an object due to its motion.
Kinetic energy remains the same at a constant temperature but increases with an increase in temperature.
At a given temperature, the temperature is the measure of the average kinetic energy of all the molecules. With the increase in temperature of the molecule, some of the absorbed energy is stored within the particles and some of the energy contributed to the motion of the molecules. This causes change in average kinetic energy of molecules due to an increase in temperature.
The root mean square (RMS) speed of the molecules is the square root of the average of each individual velocity squared.
Hence, the correct answer is "(D)."
If Chicago had experienced its average highest temperature
in August, which month would have had the longest day? Explain your
reasoning.
Answers
If Chicago had experienced its average highest temperature in August, the longest day remains the same and that is the 21st of June.
What is the effect of temperature on the length of the day?The effect of temperature induces the combination of more direct rays of the sunlight as the result of the tilting of the earth's hemisphere towards the sun to receive more solar energy and possess a warmer temperature.
But the temperature of a particular region also depends on the humidity and other abiotic parameters. So, if Chicago had experienced its average highest temperature in August, it does not mean that the longest day is in the month of August. It will remain, as usual, i.e 21 June.
Therefore, if Chicago experienced its average highest temperature in August, the longest day remains the same and that is the 21st of June.

Which condition must be met for conduction to occur?
particles must be large
particles must be small
particles must be in contact
particles must be spread apart
Answers
The condition that must be met for conduction to occur is particles must be in contact. Therefore, the correct option is option C.
What is conduction flow of heat?A pan heats up when you place it on the flame. It's because heat is transferred from the burner to the pan. Also, it allows any other utensil or pan to heat up. Yet after a while, the vessel cools down when you remove it from the heat. That happens because the vessel's heat is dissipated onto the surrounding area.
It enables the vessel to cool. Heat is passed from a warm object towards the cold object in both situations. Typically, it occurs in every situation. Conduction is the process through which heat is transported from one object's hot end to its cool end. The condition that must be met for conduction to occur is particles must be in contact.
Therefore, the correct option is option C.

The infrared radiation in the electromagnetic spectrum is come in between ultraviolet waves and microwaves. It have high frequency than microwave and low frequency than UV rays. Thus option D is correct.
What is electromagnetic spectrum?Electromagnetic spectrum is the arrangement of different radiations in the order of increasing frequency or increasing energy thus in the decreasing order of wavelength.
The longer wave is radio waves with lowest energy and then microwave after that infrared waves are arranged in the spectrum. Thus next from visible light to UV, gamma and x-rays energy and frequency increases.
Higher wavelength radiations are less powerful but travel more distance where as shorter waves are more powerful but travel less. Thus, the radiation have less frequency than UV rays but high frequency than microwave is Infrared rays. Option D is correct.
