Question: 23 Can water, ice and steam exist at the same temperature? View the answerHide answer Yes, it can do so at its ‘triple point.’ Question: 24 What colour is liquid oxygen? View the answerHide answer Blue. Question: 25 What colour does potassium nitrate burn? View the answerHide answer Violet. Question: 26 True or false: The Eiffel Tower is taller in summer than it is in winter. View the answerHide answer True. Metals expand as they are heated, and this can cause metal structures to stretch with temperature changes. Question: 27 What metal has the highest melting point? View the answerHide answer Tungsten, with a melting point of 3,422°C. Question: 28 What is the melting point of steel? View the answerHide answer 1,510°C Question: 29 True or false: Saltwater has a higher boiling point then pure water. View the answerHide answer True. Question: 30 True or false: Pure water can freeze and boil at temperatures other than 0°C and 100°C. View the answerHide answer True. The boiling point of a material is not just dependent on the temperature of the material, but also the pressure that it is under. This is why you can boil water at about 71°C at the top of Mount Everest. Question: 31 True or False: "Chemistry" comes from the French word "chemise". View the answerHide answer False. The word “Chemistry” comes from “Alchemy”. “Chemise” means shirt in French. Question: 32 Which one of these elements is NOT named after a place?

View the answerHide answer Dihydrogen monoxide Question: 34 Which of these is NOT a real element? Thorium, Adamantium, Plutonium or Promethium View the answerHide answer Adamantium. Wolverine’s claws are made of Adamantium, but it’s not a real metal! Question: 35 In Australia we use degree Celsius (°C) when measuring temperature. In America they use degree Fahrenheit (℉). What unit do scientists all over the world use? View the answerHide answer Kelvin Question: 36 Our bodies need iron! Where in the body is most of the iron found? View the answerHide answer Our blood Question: 37 The opposite of an explosion is: View the answerHide answer ... an implosion.

View the answerHide answer True Question: 39 Alfred Nobel, the creator of the Nobel Prize, was most famous for which invention? View the answerHide answer Dynamite. He did also invent the blasting jelly and detonators, and over 300 other things from synthetic materials to other explosive-related things. Even though he came up with all this stuff that was used by the military, he became a pacifist in later life. Question: 40 In the Looney Tunes cartoons, Wile E. Coyote often tries to blow up Road Runner with TNT. What does TNT stand for? View the answerHide answer Trinitrotoluene. Also, TNT and dynamite are totally different!

Question: 42 A Christmas cracker goes bang because... View the answerHide answer It contains a friction-activated chemical explosive. Question: 43 When a material goes from a solid to a gas, without becoming a liquid, this is known as? View the answerHide answer Sublimation Question: 44 When a material goes from a gas to a solid, without becoming a liquid, this is known as? View the answerHide answer Deposition Question: 45 True or False: the word “atom” comes from the Greek word for “indivisible” (meaning cannot be cut). View the answerHide answer True Question: 46 What is the most common state of matter in the universe? View the answerHide answer Plasma. Basically a soup of gases that have been stripped of some of their electrons, at extreme temperatures. As far as we know, it’s the most abundant because stars are mostly plasma! Question: 47 What is the coldest possible temperature in the universe? View the answerHide answer -273°C. This is called “Absolute Zero”, the point at which particles stop moving. Since temperature and heat is a measure of how much energy a particle has to jiggle with, and you can move any less than not moving at all, this is the coldest possible temperature anything can be. Question: 48 True or False: Gas can be turned into a liquid through pressure. View the answerHide answer True. By squeezing all the gas molecules tightly together a gas can become liquid. Question: 49 Approximately how many atoms are there in a typical human? View the answerHide answer 7 billion billion billion. That’s 7 followed by 27 0’s, try writing that down! Question: 50 In really old cathedrals and churches, you can sometimes find window glass that is thicker at the bottom than at the top Is glass a solid or a liquid? View the answerHide answer Neither. It is an amorphous solid—a state somewhere between those two states of matter. Solids are highly organised structures, and liquids are not. Amorphous means that it’s ordered, but not as highly as solids. Question: 51 There are many different types of mixtures. What do we call a liquid mixed throughout another liquid? View the answerHide answer Emulsion. Milk and mayonnaise are examples of emulsions of oil/water. Love Science? Subscribe! Join our newsletter Receive more lesson plans and fun science ideas.
