Answer:
C. its particles move farther apart and the substance becomes a gas.
Explanation:
A. is wrong because moving closer together creates a solid, not a gas.
B. is wrong because moving father apart creates a gas, not solid.
C. is correct because moving farther apart creates a gas.
D. is wrong because when heat is added particles spread apart because they vibrate faster. Although, in a solid the particles are closer together.
- Just know the states of matter and how the particles move and that will help with this problem.
Material C. the less dense is easier to move through than the more dense, so the light moves faster. Its like light moving through less dense glass, then moving through a more dense wall.
1. your skin is full of nerves. The skin feels the cold temperature which tells the nerves it is cold. the nerves then send signals to target muscle to start shivering. the rapid movement of the muscles then create heat, which keeps your body temperature where it should be.
2. if a person has high blood glucose levels, that means the body has too much sugar. This could mean that the pancreas is not producing enough insulin, which is a hormone that helps your body use the sugar for energy.
3.0 liters is equal to 183.071 cubic inches or .793 gallons or 101.422 fluid ounces. Hope that covers it.
Hi!
First of all, the melting of ice cream is not a chemical reaction, because there is no change in the components of the ice cream and if you freeze the ice cream again, you will get the same ice cream that you had previously.
The melting of ice cream is an example of a physical change, in which a substance goes from solid to liquid state, and it is an endothermic physical change.
When you freeze ice cream, the heat is removed from the ice cream, making it an exothermic process, when heat is liberated to the environment and it's taken away from the substance, in this case, the ice cream.
