Chemistry

100

This type of matter has a definite volume but no definite shape... A: Solids, B: Liquids, C: Gases, D: Plasma

What is B: Liquids. Liquids have a definite volume but no definite shape. Because the intermolecular forces are weak in a liquid, it is able to change its shape to conform to its container.

200

This English chemist and physicist discovered hydrogen. A: Sir William Crookes, B: Henry Cavendish, C: Dorothy Hodgkin, D: Bernard Shaw

Who is B: Henry Cavendish. This English chemist and physicist not only discovered hydrogen, but also determined the mass of the Earth.

300

Matter that does not enter chemical reactions is described as this... A: Inhibited, B: Inert, C: Grounded, D: Radioactive

What is B: Inert. Inert matter does not enter chemical reactions.

400

These substances control the rates of chemical reactions... A: Reactants, B: Catalysts, C: Isotopes, D: Cathodes

What is B: Catalysts. Catalysts are substances that control the rates of chemical reactions.

500

These are microscopic spheres of 60 atoms of pure carbon in a spherelike structure that resembles a geodesic dome... A: Hydrocarbons, B: Lipids, C: Crystals, D: Buckyballs

What is D: Buckyballs. "Buckyballs" are microscopic spheres of 60 atoms of pure carbon in a spherelike structure that resembles a geodosic dome. Also called fullerenes or buckminsterfullerenes, they were named after R. Buckminster Fuller who invented the geodosic dome. Buckyballs are of great interest to scientists because they contain a cavity large enough to hold other elements, even whole molecules. Once an element has been deposited into the cavity, it cannot emerge without being heated to high temperatures. This technology may someday be used to deliver medication to specific locations within the body.

Geology

100

This geologic formation may be found overhead if you are in a cave... A: stalactites B: stalagmites C: mightymites D: termites

What is A: stalactites. The ones growing downward are stalactites, the ones growing upward are stalagmites. Stalactites are formed by the deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions.

200

This type of water weighs the most... A: seawater B: distilled water C: tap water D: none - They all have the same weight.

What is A: sea water. It is loaded with mineral salts and weighs about a pound and a half more per cubic foot than fresh water at the same temperature.

300

This is the hardest naturally occurring substance... A: emerald B: tourmaline C: diamond D: corrundum

What is C: Diamond. Diamond is also one of the most valuable natural substances. Diamonds are crystals formed almost entirely of carbon. Because of its hardness, the diamond is the most enduring of all gemstones. They are among the most costly jewels in the world, partly because they are rare, Only four important diamond fields have been found - in Africa, South America, India, and the Soviet Union.

400

The largest hailstone recorded was closest to this object in diameter... A: basketball B: softball C: tennis ball D: golf ball

What is A: basketball. The largest hailstone ever recorded was 17.5 inches in diameter - bigger than a basketball.

500

The first Earth Day was celebrated in this year... A: 1950 B: 1960 C: 1970 D: 1980

What is C: 1970. The first Earth Day was celebrated on April 22, 1970, and has been celebrated each year following on April 22nd. The original purpose of Earth Day was to inspire people to think and act more environmentally. Earth Day falls on or around the birthdays of several environmental spokespersons.
