What happens when a potassium atom becomes an ion? The ions are charged because the number of negatively charged electrons no longer cancels out the number of positively charged protons. Potassium forms ions with a positive charge. Potassium loses one electron when it reacts with chlorine. This electron is transferred to a chlorine atom to […]

How much more powerful is fusion than fission?
How much more powerful is fusion than fission? Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass). Does Fusion produce more energy than […]

What happens if you burn sugar?
What happens if you burn sugar? Sugar is made of carbon, hydrogen and oxygen atoms. When heated over a candle, these elements react with the fire to turn into a liquid. The heat causes the sugar’s atoms to combine with the oxygen in the air, forming new groups of atoms. Energy is released in this […]

How long should you hold your stretch for?
How long should you hold your stretch for? For optimal results, you should spend a total of 60 seconds on each stretching exercise. So, if you can hold a particular stretch for 15 seconds, repeating it three more times would be ideal. If you can hold the stretch for 20 seconds, two more repetitions would […]
Does cold weather affect radio signals?
Does cold weather affect radio signals? In conclusion, both temperature and humidity have an effect on the transmission of radio waves. Conclusion 1: The temperature is inversely proportional to the strength of radio waves, Conclusion 2: The relative humidity in the air is inversely proportional to the strength of radio waves. What is a safe […]
What are the evidences of physical and chemical changes?
What are the evidences of physical and chemical changes? Common physical changes include melting, change of size, volume, color, density, and crystal form. The classic baking soda and vinegar reaction provides evidence of a chemical change due to the formation of a gas and a temperature change. Is a change in texture physical or chemical? […]
