That depends upon the body that you are talking about but usually the volume would go up as well. They are directly proportional.
Answer:
The correct option is 3. No, because atoms are not rearranged to create new substances.
Explanation:
A chemical reaction can be described as a reaction in which reactants combine to form new products. For example, the burning of wood is a chemical reaction.
A physical reaction can be described as the one in which no new products are made. The state of a substance might change from one form to another but no new substance is made. For example, the changing of the state of ice water into liquid water. A new product is not formed in this reaction hence, it is not a chemical reaction.
Answer:
Explanation:
Here, we want to get how the acid deposition will affect mount Mitchell
From the question, we have it that the forest has thinned as a result of pollution and acid deposition
What this simply means is that there would be a lesser number of trees in the forest
This leads to the amount of carbon iv oxide being absorbed by the forest to decrease (trees utilize carbon iv oxide in photosynthesis)
Hence, the correct answer choice here is that there will be fewer trees to absorb carbon dioxide from the atmosphere
