• two cans (one quite small like a soup can and the other large, like a juice, can.)
Follow these steps:
A. Remove the top of each can. Punch a hole in the side of each can, very close to the bottom, making sure the holes are equal in size. Cover each hole with a piece of tape, and place the cans next to the sink.
B. Put water in both cans, making sure the water is at the same level - different amounts, but the same level. Turn the cans so the holes are facing into the sink, and remove the tape at the same time. Answer these questions: Do the streams of water shoot out at the same distance? Why or why not?
C. Try the same experiment, but this time put one cup of water in each can. What happens to the streams of water now?
D. Try the same experiment, but this time fill both cans to the top. What happens to the streams of water?
ANSWER A B C AND D CORRECTLY!!!
the water flows faster out of a smaller can than it does a larger can.
Answer:
A&B: The stem of the water does not shoot out the same distance because one can have less water and the other can have more water and the can with less water have more pressure that making the can shoot out further than the can with more water.
C: Less water will come out of the two cans because they are compressed together so all of the water is trying to come out all at the same time.
D:All of the water in the can started coming out all in one small stream.
Explanation:
In open system such as campfire matter can be exchanged between system and surroundings.
Matter in chemistry, is defined as any kind of substance that has mass and occupies space that means it has volume .Matter is composed up of atoms which may or not be of same type.
Atoms are further made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.
The states of matter are inter convertible into each other by changing the parameters of temperature and pressure.In open systems which are not limited by the boundaries exchange of matter can take place between system and surroundings .

Answer:
A
Explanation:
Answer:
(A) Bring water to the plants in the ecosystem.
Answer:
Because most of the human body (about 70% of it) consists of water
Explanation:
The main reason why the specific heat capacity of the human body is very close to that of water is that water makes approximately 70% of the substances of which the human body consists. However, the human body has a slightly smaller specific heat capacity than water, because it contains also other elements/substances, and since water is one of the substances with the higher specific heat capacity at all, the specific heat capacity of the body is a bit smaller.
