Matter exists in three different states: solid, liquid or gaseous. Follow this scientific experiment to see how it is possible to change the state of a given solution or compound using different methods, from very simple to very complex ones.
Steps
Method 1 of 4: Freezing
Step 1. Place a small container with water in the freezer
Step 2. Leave it for several hours or overnight
Step 3. Remove it from the freezer and check what happened
Water changes from liquid to solid when it reaches 0 degrees Celsius, or 32 degrees Fahrenheit. This is a simple example of a transition from liquid to solid state.
Method 2 of 4: Crystallization
Step 1. Dissolve a lump or loose sugar in a small container of water until it absorbs no more (about a cup of sugar for half a cup of water)
You have created a solution, which is the combination of more than one compound.
Step 2. Place a piece of string inside the solution, with one end fixed to the edge of the container
Step 3. Place a lid on the bowl, and let it rest
After several weeks, you will find crystals on the wire, obtained through the crystallization process.
Method 3 of 4: Polymerization
Step 1. Purchase a small epoxy glue kit or fiberglass repair kit
This activity must be supervised by an adult.
Step 2. Put the epoxy glue into a mixing syringe or pour the glass (polyester) resin into a can or other metal container, and mix the catalyst thoroughly with a suitable utensil
In a few minutes the liquid will start to heat up, and depending on the temperature and the product you are using it should solidify in less than a week.
Method 4 of 4: Evaporation
Step 1. Dissolve the table salt in water
Several tablespoons of salt in a quarter cup of water should be fine. br>
Step 2. Pour the solution into the largest container you can find and place it uncovered in a quiet place where it can rest, preferably outdoors if the climate is hot and windy
When the water has evaporated, the salt will return to its solid state thanks to a process called evaporation.
