Here is a preview of what awaits you in this physics and chemistry quiz: 15 multiple choice questions, each with a detailed explanation so you can learn while you play. Below are a few sample questions (and their answers, so no peeking before you play!).
What is the chemical symbol for gold?
Answer: Au. The chemical symbol for gold is Au, from the Latin "aurum". Gold has atomic number 79 and is a transition metal. Ag is the symbol for silver (argentum).
How many commonly observed states of matter are there?
Answer: 3. The three commonly observed states of matter are solid, liquid and gas. Plasma is a fourth state, but it is much rarer in everyday life (it is found in stars and some lamps).
What is the SI unit of force?
Answer: The newton. The newton (N) is the SI unit of force. One newton is the force needed to accelerate a mass of one kilogram at one metre per second squared.
What is the pH of a neutral solution at 25°C?
Answer: 7. The pH of a neutral solution at 25°C is 7. A pH below 7 indicates an acidic solution, while a pH above 7 indicates a basic (alkaline) solution. Pure water has a pH of 7.
Which subatomic particle was discovered at CERN in 2012, confirming the Standard Model?
Answer: The Higgs boson. The Higgs boson was discovered at CERN in 2012 thanks to the Large Hadron Collider (LHC). This particle, predicted by Peter Higgs in 1964, explains how other particles acquire their mass.
