How does the temperature of water affect its ability to hold oxygen?
Answer:The solubility of oxygen and other gases will decrease as temperature increases 9. This means that colder lakes and streams can hold more dissolved oxygen than warmer waters. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive.

Match the part of the wave to its description
Answer:
Crest Highest Point of the wave
Trough Lowest Point of the wave
Amplitude the height from mid point to the crest or trough
Wavelength Distance from one crest to another
The match of the wave is
Crest ⇒ Highest point of the wave.
Trough ⇒ Lowest point of the wave.
Amplitude ⇒ Height from mid point to the crest or trough
Wavelength ⇒ Distance from one crest to another.
What is wavelength?Wavelength the distance a wave travels in the time it takes a medium particle to complete one vibration. The letter k stands for it. The meter is its SI unit.
What is amplitude?
Amplitude can be referred to as the maximum displacement caused by the vibrating particle. A is the symbol for it. The meter is its SI unit.

Match the terms
1.the total energy of any closed system, including all internal kinetic and potential energy of the system
2.a measure of the average kinetic energy of particles in an object
3.something that flows into a substance
Terms-
Temperature
Heat
Thermal Energy
Answer:
1-thermal energy, 2-tempurature, 3-heat
Explanation:
The correct match of the terms and their definitions are:
1. Thermal energy – the total energy of any closed system, including all internal kinetic and potential energy of the system.
2. Temperature – a measure of the average kinetic energy of particles in an object
3. Heat – something that flows into a substance
What is thermal energy?Thermal energy is the energy that is formed by heat. It is produced when the temperature of a body increases. This cause the molecules and atoms to run or move fast or collide with each other.
Heat is a form of energy that is produced when the temperature of a substance increases. Heat, thermal energy, and temperature are interconnected to each other.
When the temperature rises, the heat or thermal energy in the body increase, which cause the movement of atoms faster, and the atoms collide with each other.
Thus, the correct match is 1- thermal energy, 2- temperature, and 3- heat.

Describe the kinetic energy/ movement of the particles in plasma.
Answer:
Plasma is the highest energy state kf matter consisting of a collection of free-moving electrons, positive ions and neutral particles.
How do particals move around in plasma? plasma particles are spred our and move around randomly, but unlike gas, they contain some free ions and electrons, which gives plasma its ability to conduct electricity.
what is kinetic energy? A form energy that an object or particle by reason of motion. Dictionary def.- energy which a body possesses by virtue if being in motion.

In two or more complete sentences explain how to balance the chemical equation,
Ca + N2 ⟶ Ca3 + N2 and include all steps.
Answer:
to balance this equation, your going to put a 2 in front of the "Ca" then that makes the equation look like this "2Ca + N2 ⟶ Ca3 + N2" since the "Ca" had one atom, we added two more atoms
as we all know 1 + 2 = 3
then that gives us 3 "Ca's" on both sides

Which of Newton's 3 Laws explains a rocket lifting off? *
Law of inertia
Law of Acceleration
Law of Action-Reaction
Answer:
Newton's Third Law of Motion
Explanation:
A rocket expels hot gases at a very high pressure very quickly, and these gases have lots of energy, and according to Newton's third law, every action has an equal and opposite reaction. So, expel lots of gas at a high rate, and the energy of the gases being pushed out propels the rocket upward. Hope that helps!

How does the amount of water in a glass affect the pitch of the sound it produces?
Answer:
the more water the higher the pitch the less water the lower it is
Answer:
The glass with the most water has the lowest pitch. The glass with the least amount of water has the highest pitch.
Explanation:Tapping the glasses causes the air to vibrate. When the air column is shorter, the air vibrates faster and the pitch is higher.

What are some ways your body regulates the increase of body temperature that also occurs when exercising?
Answer:
Doing push-ups
Explanation:
When you workout you get hot so the tempeture of ur body increase.
Some ways by which your body regulates the increase of body temperature that also occurs when exercising are evaporation of sweat and skin blood flow.
What is effect of exercising on body temperature?
Our muscles quickly deplete stored energy when you start exercising. To make more energy, muscles combine oxygen with adenosine triphosphate or ATP. This process creates heat energy as a byproduct. Muscles generate the most heat because they produce so much energy.
Extra heat raises your body temperature, so your body needs to eliminate heat as quickly as possible.
Therefore, some ways by which your body regulates the increase of body temperature that also occurs when exercising are evaporation of sweat and skin blood flow.

What is a diaphragm? What does it do?
The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.
Explanation:
Diaphragm contracts and expands when you breathe air
Answer:
A diaphragm on a microscope is the piece that enables the user to adjust the amount of light that is focused under the specimen being observed. A diaphragm is typically found on higher-power microscopes versus less expensive or toy models. The diaphragm is located directly under the stage or platform where user places the specimen or slide.
