Distillation Experiment

Today in science we are learning about Evaporation,Distillation and Condensation.

Aim:

To separate a solute from a solvent in a solution using distillation.

Method:

1.Set up the equipment  as shown on the diagram.

2.A mixture of coke and water was heated in a conical flask…

3.The water evaporates leaving the coke behind…

4.The water vapour flows through the delivery tube…

5.Heat the solution until most of the solvent has evaporated.

6.Then turn your element off.

Results:We saw the coke bubble then it started boil because of the heat.

Discussion:The photo with the flask that has a layer of coke on the bottom of the flask had that layer because the liquid was separated from the coke mixture by being boiled.

But the other coke mixture that is coke zero has a layer of sugar on the bottom of the flask that is because the coke zero has less sugar in the coke zero mixture.

Distillation: First the coke started boiling because it was being heated by the element, then the liquid evaporated and turned into a gas and went into the delivery tube next the  gas condensed and turned into solvent because it was cooled down by sitting in the ice that was in the beaker and the solute was left in the bottom of the flask.

Water cycle experiment.

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	Yes	Yes	Yes
Amount of Water	2	2	2
Acidity	1	3	1

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large 

Other comments:

Bag 1

1 Bag 1 cycled water

2 Bag 1 had a small amount of water.

3 The acidity in bag 1 was low.

Bag 2

4.Bag 2 cycled water.

5.Bag 2 had a small amount of water.

6.Bag 2 had a large amount of acid.

Bag 3:

7.Bag 3 cycled water.

8.Bag 3 had a small amount of water.

9.Bag 3 had none acid at all.

Conclusion:

Bag 1:

Bag 1 cycled water it only had a little amount of  water and the acidity in bag 1 was really low.

Bag 2:

Bag 2 had a small amount of water it cycled water and had a large amount of acid.

Bag 3:

Bag 3 cycled water and had a small amount of water and had no acid at all.

Investigation

You can decide on how you would like to do this investigation. Your presentation could be on the blog, slides, or Powerpoint.

Write a definition, upload an image and list where these fossil fuels are mined.

1. Coal Definition: A combustible black or dark brown rock consisting chiefly of carbonized plant matter, found mainly in underground seams and used as fuel
2. Oil Defintion: A liquid preparation used on the hair or skin as a cosmetic
3. Natural Gas:Is mined in underground rocks.

Write a paragraph and upload an image about each of these renewable energy.

1. Solar is basically a type of technology that gives us renewable power from the sun or from riversSolar energy works by capturing the sun’s energy and turning it into electricity for your homes buisnesses and many more things
2. Wind:Wind turbines generates electricity by using the natural power in the wind. 
3. Waves: Power from the wave generates electricity.HydroAs the wind passes over the surface of the oceans, a portion of the winds kinetic energy is transferred to the water below, generating waves.
