Answer:
C. Solid
Explanation:
It's most about the kinetic energy, when molecules have the least amount of room to move around, they have the least amount of energy.
For example if you think about gas and how spread out the molecules are in order to evaporate, there it the highest amount of energy there.
Answer:
The sun is important to Earth because it helps regulate the climate, is the main source of energy for producers in the ecosystems and it keeps the oceans from freezing, along with providing light. If just one of these factors changed dramatically, it would impact all life on Earth. Without the sun, the planet’s oceans would freeze, temperatures would drop and all life would die off without light or food.
The sun is important to every single aspect of life on the planet. Human life could not exist without it because it would cause all of the water and food sources to cease to exist. The sun is in no danger of disappearing any time soon. Scientists estimate the sun has at least another 5 billion years before it turns into a red giant and swallows up Mercury and Venus. It will also destroy all life on Earth because it will be close to the planet once that change occurs. The temperature of the sun will also increase tenfold from 18 million to 180 million degrees Fahrenheit. The increase in the sun’s size when it finally begins to change will be due to the heat increase causing expansion.
Without the sun, we would no energy to live, no plants to eat, no trees to give us oxygen or animals to roam. We would not have gravity to keep the earth in orbit. Without the sun, the earth would be dark and cold and life would quickly disappear.
Answer:
heat energy to keep you warm and light energy to be able to read your book
Explanation:
Mass of Oxygen required : 24 grams
<h3>Further explanation</h3>
Given
3 moles of H
1.5 moles of O
3 moles of H₂O
Required
Mass of O
Solution
Reaction
2H₂ + O₂ ⇒ 2H₂O
Mass of Oxygen for 1.5 moles of O :
= mol x Ar O
= 1.5 moles x 16 g/mol
= 24 grams
