How can you determine if the liquid is water? A very easy solution is to take a sample of colourless liquid and put on stove if it starts boiling exactly at 100 ºC then it is pure water. Any other colourless liquid such as vinegar always have different boiling point. How do you identify whether […]
Why did Germany worry about the alliance between France and Russia?
Why did Germany worry about the alliance between France and Russia? 1 Answer. Probably because Germany was and still is located in between the two nations and, in case of war, would have been forced to fight on two fronts simultaneously (a not very strategical advantageous situation indeed!). Is France allied with Russia? Dual Alliance, […]

What is the relationship between rolling static and sliding friction?
What is the relationship between rolling static and sliding friction? Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases. What is the cause of friction What is the difference between […]

What happens when a solid turns into a liquid?
What happens when a solid turns into a liquid? When a solid is heated the particles gain energy and start to vibrate faster and faster. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are […]
What is the characteristics of other planets in the solar system?
What is the characteristics of other planets in the solar system? The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, […]
