Precipitation exceeds evaporation over the land.
(2) 37°C (4) 298 K
Answer;
37 ° C
Explanation;
-The average kinetic energy of gas particles is directly proportional to the the temperature. An increase in temperature increases the speed at which the gas molecules move, and thus increasing their kinetic energy. At any given temperature gases have the same kinetic energy.
-Hence, the temperature at which Helium gas will have the highest kinetic energy is at the highest temperature, which is 37° Celsius.
Answer:
2: 37°C
Explanation:
This is because the temperature at which Helium gas will have the highest kinetic energy is at the highest temperature, which is 37° Celsius.
B) It attempts to explain why things happen.
C) It describes what happens in the world around us.
D) It must be supported by many independent scientific investigations.
2)Observation and experimentation have led many scientists to accept a theory about the origin of the universe. This theory is called the Big Bang Theory. Scientific evidence collected and observed by scientists around the world suggests that the universe is ever expanding from a hot and dense initial state. What makes this a scientific theory?
A)It has been proven by several scientists independently, resulting in its being accepted as truth.
B)It is based on the beliefs and opinions of the majority of the scientific community.
C)It is an observation of the natural world that has been proven as fact.
D)It is the best explanation that scientists can offer, based on many scientific investigations.
3)A scientist in Italy published his findings from a scientific investigation that he conducted. Other scientists from around the world conducted similar investigations to test the results. All of the investigations result in similar findings. What does this say about the findings of these investigations?
A)They have been proven to be scientific fact because all the investigations gave similar findings.
B)The findings are automatically promoted to a law because they were proven by so many scientists.
C)They are ready to be published in the media and in text books as a new scientific theory.
D)The results are considered more reliable because they were documented by separate investigations.
4)Which of the following is not an example of kinetic energy?
A)mechanical energy
B)nuclear energy
C)electrical energy
D)thermal energy
A) It must be verified by scientists around the world.
A scientific law is a way to describe a phenomenon that occurs in our universe. In order for a research to become law, it must be accepcted by the vast majority - if not all - of the scientists in the same field. However, they do not have to verify the potential law, they can choose to falsify or just to accept proofs taken by the discovers.

A)It has been proven by several scientists independently, resulting in its being accepted as truth.
The Big bang is a scientific theory that explain how our universe was born. Before becoming a theory and becoming the "fact" we assume it is, it was long subject of study, and it was accepted only when different study from different scientists pointed out in the same direction. Hoever, ever today, study continues to have a better understanding of the phenomenon.

D)The results are considered more reliable because they were documented by separate investigations.
When different experiments are made, and they gave out similar results, the results become more reliable, as they are been proven by different sources in an indipendent way. However, this do not imply a pubblication or the trasformation of the results into a scientific law, as those steps go through a different process.

B)nuclear energy
C)electrical energy
D)thermal energy
Only mechanical energy is a type of kinetic energy. Kinetic energy means an energy that derives from a movement. Nuclear energy, electrical energy and thermal energy are other forms of energy. Energy from one of these sources could be converted into kinetic energy, or kinetic energy could be used to generate other forms of energy.

Answer:
Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.

Answer : The valley between the two peaks is usually referred to intermediate formation of the reaction. The two mountain peaks when formed in a reaction the stable phase between them is exactly when an intermediate is formed and often observed on the curve.
