Answer:
Student 3
Explanation:
This question lets us know something about how the density of a gas varies with temperature.
When a gas is heated, its molecules spread out and expand. When this happens, the volume of the gas increases. Remember that density is defined as mass/volume. Thus as the volume increases, the density of the gas decreases.
Therefore, the carbon dioxide rose up because the heat expanded the gas and it became less dense.
B. ribonucleic acid is the answer your looking for
The prefix di- means that there are two nitrogens.
Just like in carbon dioxide (CO2) there is one carbon and two oxides
Answer:
0.99 pounds
2,000 oz
0.423 cups
Explanation:
In order to convert this units we need to look up their equivalences.
1 g equals 0,0022 pounds approximately
Then we need to cross-multiply:
450 g equals 0.99 pounds approximately
We can do the same calculation for the other 2 ingredients
1 g equals 16 oz
Then (125 g x 16 oz) / 1 oz = 2,000 oz (or 500 4 oz)
1 cup equals 236.59 ml
Then (100 ml x 1 cup)/ 236.59 = 0.423 cups
the conversion of liquid to vapours is a change in state of a system from one state to other
there are basic two differences between three states of matter
1. thermal energy: gas has highest thermal energy tthen liquid and least us of solids
2. intermolecular forces of attractions
solids have highest intermolecular forces of attraction , then liquid and least in gas
sovas we increase the temperature the forces if attraction decrease s and thermal energy increases.
So when we heat liquid more moleculws gets energised attaining thermal motion in the range of gas thus the rate if evaporation increases.
