Which liquid will dissolve the Peppermint Candy Canes the fastest? Follow Dr. Boyd’s explanation to set up your experiment. Just remember to come up with your own hypothesis before you start the experiment. Once you’ve come up with your...

Yes, metals can exist in gaseous forms. To illustrate, let's consider lead, which has a boiling point of 1740°C. When heated past its melting point of 327°C, lead turns into a gas at 1740°C. Another notable example is mercury, which...

Water especially the one which flows through the pipe contains atmospheric gases, such as nitrogen and oxygen, dissolved in it. As the glass filled with water sits out for a few hours, its temperature rises slightly (water gets warmer),...

When Mendeleev created the Periodic Table in 1869, he also predicted the existence of elements yet to be discovered, including gallium. What are the properties of this rare metal and why was its discovery so important? Chemistry -...

Discover the role played by intermolecular forces in changing the state of matter between solid, liquid and gas. Chemistry - Atoms And Bonding - Learning Points. Intermolecular forces are the attractive forces between molecules....

We demonstrate denaturing by adding the enzyme trypsin to photographic film. Strips of photographic film are added to trypsin solution at different temperatures to determine the optimum conditions for the enzyme. In the right conditions...

Halogens are hazardous to human life, yet they can also be very useful. How do they react when they meet other elements? Chemistry - Periodic Table - Learning Points. The halogens are the elements in Group 7 of the periodic table. The...

We use a supersaturated solution of sodium ethanoate to demonstrate instant crystallisation. Sodium ethanoate is added to water and is then heated to allow all of the crystals to dissolve. When it is cooled it forms a supersaturated...
