<span>Answer: It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.
Explanation:
Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.

When moist air cools below its dew point on a cold surface it forms dew. It is in the liquid state.
Rain is again a form of precipitation in which water is in the liquid state.
When air temperature is below freezing, the precipitation that results is referred to as frost. Hail is a form of precipitation in the ice balls whereas as sleet is a mixture of rain and snow.
Ans: Forms of frozen water- frost, hail and sleet
Answer:

Explanation:
Hello,
In this case we use the Boyle's law which allows us to understand the volume-pressure behavior as an inversely proportional relationship:

Whereas we solve for
as the required final pressure:

Best regards.
Let A be the 80% solution and B be the 20% solution and P be the produce solution of 70%. Va and Vb and Vp are the volumes of A and B and P respectively.
Va + 60 = Vp
0.7Vp = 0.8Va + 0.2(60)
Substituting the value of Vp from the first equation:
0.7(Va + 60) = 0.8Va + 12
30 = 0.1Va
Va = 300 gallons
