First, boiling is the change of state from a liquid to a gas. Second, boiling of a pure substance occurs at a particular constant temperature called boiling point.
First, the change of state from a gas to a liquid is called condensation. Second, a pure substance condenses at a temperature equal to its boiling point.
Hope this helps you!

By trying to help them, and spread positivity, and just be kind to everybody. :D
Explanation:
Europe is not a typically dry place (unlike for exampe Mesopotamia) so it does not need rivers for irrigation.
Instead, rivers are needed more for transport - they have served as a means of communication and for the exchange of goods.
For example, Danube allowed a big-scale trade between the cities lying on it: Vienna, Budapest and Bratislava.
Answer:
Energy use is related to economic growth.
Explanation:
Energy use and economic growth go hand in hand. We can not say that more energy usage leads to economic growth, or that bigger economic growth leads to bigger usage of energy, simply because one can not do anything without the other. To put it simply, energy use and economic growth occur at the same time because of their interdependence.
What can be said is that energy use and economic growth grow together, so the more developed a country is, the more energy it uses, and the less developed a country is, the less energy it uses. A lot of countries in the world face big problems when it comes to satisfying their energy demands because they lack the natural resources to produce it, so often they are dependent on other countries for their development. On the other hand, there are also countries that have an abundance of natural resources for energy production but they simply don't use them adequately and responsibly so they are not developed as one would expect.
Humans will survive by looking for alternative water sources as the Sun becoming a red giant means rapid evaporation of the earth's ocean.
<h3>What is Evaporation?</h3>
This is referred as the type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
Water is important for our daily living and activities which is why alternative sources must be designed to tackle the rapid evaporation pattern.
