How would you describe the appearance of the substance before the phase change?

Answers

The appearance of the substance before the phase change can be described as Melting, Vaporization, Sublimation, Condensation.

Melting:

When a substance converts from the solid to the liquid.

Vaporization:

The substance changes from a liquid to a gas.

Condensation:

When a substance converts from a gas to a liquid.

Sublimation:

When a substance converts directly from a solid to a gas without going through the liquid phase.

Therefore, the appearance of the substance before the phase change can be described as Melting, Vaporization, Sublimation, Condensation.

The temperature of the areas surrounding Kochi before each storm was about 10°C and there was the same amount of water vapor in the air. Given this information, which storm do you predict will have the most rainfall and why?

Answers

I am not sure but I think storm 1
I have no logic behind it but I guess cause if it’s 12 it could turn into ice and not rain

Storm number 1 because number 2 and 4 will be snow or ice and it wouldn’t be number 3 since 1 has wind and wind helps rain because it pushes the clouds together and the clouds hit each other and release water through them as rain.

Imaging playing a game of baseball on the moon, which has less gravity than Earth and no atmosphere. How would you want to change the game to make it play fairly and fun again?

Answers

Deflate the ball so it’s not as bouncy

A technique to change the game to make it play fairly and fun again is to deflate the ball in an attempt make it less bouncy.

Discussion:

A characteristic of the baseball game is that the baseball is less bouncy in comparison to other sports like football and basketball.

When the baseball game is played on the moon with a less gravity; the ball tends to ascend more as the force of gravity is lower compared to that of the earth.

Ultimately, lowering the air pressure in the baseball makes the ball less bouncy and the game may become fun to play again.

Rank the ten objects from loudest to softest.

Make some conclusions based on your results from Steps 1 and 2. For example, are there a certain shapes or materials that are better or worse media for sound travel?

Answers

Stairs, wall, door, window, picture, floor, desk, backpack, paper, bed.

Stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.

What is sound?

Sound is defined as an acoustic wave is a vibration that travels through a gas, liquid, or solid transmission medium. In terms of human physiology and psychology, sound is the brain's receipt of these waves and perception of them. A mechanical disturbance that causes an equilibrium condition to be disturbed and propagates through an elastic material medium.

The vibration of items creates sound, which travels from one place to another through a medium. Vibration is the phrase used to describe an object's to-and-fro or back-and-forth motion. Vibrations are generated by objects in motion.

Thus, stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.

After Michelle went on vacation for two weeks, she came home to find her potted plants had turned brown and died. The soil was very dry. While Michelle was away, she kept the curtains and windows closed and did not have a neighbor come by to water her plants. Michelle now realizes that she will have to do things differently the next time she is away for several days if she wants to keep her plants alive. Why is it important for Michelle to make sure her plants have their needs meet while she is away?

A.
She needs to make sure the plant receives water, sunlight, and air. Plants need all components to make their own food.

B.
She needs to be sure to put plant food in the pot. Plants need to be feed because they do not make their own food.

C.
She needs to add a lot of water to the pot before leaving. Plants only need moist soil to make their own food.

She needs to keep the curtains open or set the plant outside. Plants only need sunlight to make their own food.

1. The strength of the gravitational force between two objects depends on which of the following?
o the mass of the larger object
the velocities of the objects
the orbits of the objects
o the mass of the objects and the distance between them

Answers

Answer:

Explanation:

The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.

Answer:

Newton's law likewise expresses that the strength of gravity between any two items relies upon two factors: the majority of the articles and the distance between them. Articles with more prominent mass have a more grounded power of gravity between them.

2. write a sentence that describes how the food changes in the small intestine.

3. explain what happens to digested food in the small intestine

4. write a sentence that describes what happens to digested food in the cell.

Answers

Answer:1.Once filled with food, the stomach grinds and churns the food to break it down into small particles. It then pushes the small particles of food into the first part of the small intestine, called the duodenum. The small intestine is where most of the digestion and absorption of our food takes place.2.The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.3.The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.4.The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.

Water (H2O) splits into Hydrogen Ions (H+) and Hydroxyl Ions (OH-). When there are equal parts of Hydrogen Ions (H+) and Hydroxyl Ions (OH-) leading to a 1:1 ratio, pH is neutral (7).

Explanation:

The concentration of H + ions at pH 6. The concentration of H + can be deduced by the formula pH = - log H + ==> H + = 10 ^ (- pH) ...

Concentration of -OH at pH 6. The concentration of -OH can be calculated from pOH: pOH = 14 - pH = 14 - 6 = 8. ...
