Farmer brown is planting crops in his feild s. He wants to prevent the topsoil from being blown away by the wind or washed away
from by water. Which of these steps should he take. A: plow the soil many times. B: plant crops close together. C: water crops often to wet soil. D: leave the land free of crops for a long time
Working in the plan industry, it becomes obvious that when watering the plants often, it will pack down the topsoil into the plant. Topsoil is lose at first as stated above, but when enough water gets on it, it becomes almost like mud. This is the kind of topsoil you want. No wind or water will mess it up because it already it watered! It will also help the grow. In addition, plowing is not correct because you only need to plow twice in the plant process. Before you plant the seeds, and to harvest the crops. If you plow to soon and often, you won’t have any plants.
Evaporation occurs when molecules in a liquid gain enough energy that they overcome attractions from other molecules and break away to become a gas. Adding energy increases the rate of evaporation.
In the sugar solution, there are dissolved 45g of sugar in 100mL of water. The conversion factor is <em>45g Sugar = 100mL water</em>. That means when 135g of sugar are used the amount of water is:
135g sugar * (100mL water / 45g sugar) =
<h3>300g of water was used to make the solution</h3>
