Instructions: Create a comic strip detailing the adventure of your character as the character is exposed to thermal energy, causing it to undergo phase changes from a solid, to a liquid, to a gas. Place drawings inside the boxes and written content on the lines below each box.
Your presentation must include the following:
• title and introduction of your character, including what substance it is made of
• source of thermal energy your character encountered (conduction, convection, and/or radiation)
• detailed description and/or diagram of the particle transformation from solid to liquid phase
• detailed description and/or diagram of the particle transformation from liquid to gas phase
( do not use the ice cube story)
girl how someone supposed to help you with that?!
Answer:
use water in the ocean getting precipitated and going up then make it fall off a mountain then make it freeze becuase it got stuck on the mountian
thermal energy happend when the water got precipitated
I hope it helps a bit
Sorry if there is mistakes I'm tryna help

URGENT_____The diagram below shows the same model of the greenhouse effect... Select whether each process helps WARM UP or COOL DOWN the Earth's climate. *
The process A helps cool down the earth's climate, whereas the processes B and C, helps warm up.
What is meant by greenhouse effect?When the heat from the Sun is trapped by gases in the Earth's atmosphere, this process is known as the greenhouse effect.
Here,
The Earth is substantially warmer than it would be if there were no atmosphere as a result of the greenhouse effect.
One factor that makes the Earth a sustainable place to live is the greenhouse effect.
Since the manner that the interchange of incoming and outgoing radiation heats the globe is comparable to what happens in a greenhouse, the process is known as the "greenhouse effect."
The warming of the Earth's surface is a result of the greenhouse effect. A portion of the solar energy that enters the Earth's atmosphere is reflected back into space, while the remaining energy is absorbed and re-radiated by greenhouse gases.
Hence,
The process A helps cool down the earth's climate, whereas the processes B and C, helps warm up.

Which of the following statements about digestion is/are TRUE? (Select all that apply.)
Salivary glands are located in the esophagus.
Digestion begins in the mouth.
Saliva changes the starches in food into simple sugars.
Saliva is an enzyme.
Answer:
option 1, 2, and 4
Explanation:
i took the test lol
The true statements are digestion begins in the mouth, saliva changes the starches in food into simple sugars, and saliva is an enzyme. The true options are (2), (3), and (4).
The process of breaking down food mechanically and chemically begins digestion in the mouth. When we consume, our teeth break down the food with chewing motions. By increasing the food's surface area through mechanical means, enzyme function is facilitated.
The digestion of carbohydrates, and starches, depends on the salivary enzyme amylase. When amylase disassembles the lengthy chains of starch molecules into smaller units, it creates maltose, a disaccharide (a form of sugar).
A biological enzyme is a molecular catalyst that speeds up particular chemical reactions without being consumed or changed in the process. Amylase, which was previously noted, is one of the most significant enzymes found in saliva. In the mouth, amylase aids in the first digestion of carbohydrates.
Hence, the true statements are digestion begins in the mouth, saliva changes the starches in food into simple sugars, and saliva is an enzyme. The true options are (2), (3), and (4).

A patient with a family history of cholesterol deposits in the arteries asks her doctor for a recommended vitamin. Which of these vitamins is the doctor likely to recommend?
vitamin D
vitamin C
vitamin B
vitamin F
Cholesterol deposits in the arteries can be treated by the Vitamin B (Niacin).
Why Vitamin B is used to treat cholesterol patients?The function of Vitamin B (Niacin) is to remove the LDL (low density lipo protein) from the body that is Bad cholesterol and to increase the HDL (High density Lipo protein) that is good cholesterol.
Niacin is a type of vitamin B which is used by the human body to convert the food into an energy. Niacin (Vitamin B) also improves the performance of the nervous system and digestive system and also keeps the skin healthy.
Thus Vitamin B is used to treat the cholesterol patients.

When a cannon fires a cannonball we observe Newton's third law. Which is the reaction force?
A) The cannon moving forward
B) The cannonball moving backward
C) The cannon moving backward
D) The cannonball moving forward
We have that when a cannon fires a cannonball the reaction is the opposite reaction spoken about in newton law
The cannon moving backward
Option C is correct
Newtons third law state that for every action they must be an equal and opposite reaction Therefore
When a cannon fires a cannonball we observe Newton's third law the reaction force notice is the opposite reaction spoken about in newton law
