Read the passage and identify the method being used. Crude oil is a mixture of many liquids that must be separated into pure sub

stances before we can use them. To do so, the entire mixture of liquids is heated in a furnace to 400 degrees Celsius, which is enough to evaporate all of the liquids. Then the mixed vapor is allowed to rise. As the vapor rises, it cools. When it reaches 370 degrees Celsius, fuel oil condenses from the vapor and runs down a channel to be collected as a pure substance. However, the other vapors will continue to rise and cool. Because the different substances in crude oil have different boiling points, each substance can be individually collected in the same way as fuel oil. Where once we had a mixture of liquids, after condensing the various vapors, we have four different pure substances. Which separation method is being used here?

What mass of water in grams will fill a fish tank 100 cm long, 50 cm wide, and 30 cm high?
Natasha_Volkova [10]

Answer:

150,000cm^3, or 1,500m^3

Explanation:

The question is basically asking the volume of this rectangular tank.

The formula to find the volume is length x width x height.

This is because we're trying to find the area of the base (length x width), and then we're multiplying the base times the height, to get how much of the base area can fit in the height of the rectangle.

So, the answer is 100cm x 50cm x 30cm = 150,000cm^3, or 1,500m^3, because 1 meter = 100 centimeters.
