Creating a Solid
All matter can move from one state to another. It may require extreme temperatures or extreme pressures, but it can be done. Sometimes a substance doesn't want to change states. You have to use all of your tricks when that happens. To create a solid, you have to decrease the temperature by a huge amount and then add pressure. Some of you know about liquid nitrogen (N2). It is nitrogen from the atmosphere in a liquid form and it has to be super cold to stay a liquid. What if you wanted to turn it into a solid but couldn't make it cold enough to solidify? You could increase the pressure in a sealed chamber. Eventually you would reach a point where the liquid became a solid. |
Creating a Gas
When you are a liquid and want to become a gas, you need to find a lot of energy. Once you can direct that energy into your molecules, they will start to vibrate. If they vibrate enough, they can escape the limitations of the liquid environment and become a gas. When you reach your boiling point, the molecules in your system have enough energy to become a gas. |
Creating a Liquid
The reverse is true if you are a gas. You need to lose some energy from your very excited gas atoms. The easy answer is to lower the surrounding temperature. When the temperature drops, energy will be transferred out of your gas atoms into the colder environment. When you reach the temperature of the condensation point, you become a liquid. If you were steam over a boiling pot of water and you hit a wall, the wall would be so cool that you would quickly become a liquid. The wall absorbed some of your extra energy. |
Sublimation and Deposition: Skipping the liquid phase.
Sublimation is the process by which a solid transforms into a gas without passing through the liquid stage. Deposition occurs when a gas becomes a solid without going through the liquid state of matter. Those of you who live near the equator may not have seen it, but closer to the poles we see frost on winter mornings. Those little frost crystals on plants build up when water vapor from the air becomes a solid on the leaves of plants. |

Heading in book Density.
Have a look at the image below and complete the activities in your workbook.:
- Use it to define the term density.
- What can you say about the density of solids in comparison to liquids and gasses and why?
- Have a look at the two beakers of liquid. In full sentences identify which one is more dense and explain why?
Student activities continued:
Have a look at the image over there -----------------------------> Read the text below it and use it to answer the following question.
Thinking question: Does 1kg of feathers weigh the same as 1kg of rocks? If they were in a wheelbarrow would they look to be the same size? Put a sub heading in your book that says calculating Density. Copy the information below into your workbook. |
Student Activities Continued
Watch the video over there ----------> and use it to answer the questions below into your workbook
Complete the test yourself section below in your workbook. |
|
Test yourself
Complete each of the questions in your workbook: NOTE you will probably need calculator. (If you're struggling scroll up to the calculating density box and use that formula to help you. • A rock has a mass of 150g and a volume of 30cm3 Calculate its Density • A match has a mass of 3g and a volume of 12cm3 Calculate its Density • A train has a mass of 152701g and a volume of 1309cm3 Calculate its Density |
|
Student Activities:
If we don't know the volume of an object because it has an irregular shape an easy way to find it is by placing it in water. The amount of millilitres that the water increases from its original amount shows the volume of the irregular object.
|
Videos you need to watch about density.
