Untitled Flashcards Set

Ampere, Andre-Marie

A scientist who stated that a magnetic field is produced by electricity, and its poles are perpendicular to the direction of the electric current.

Bernoulli, Daniel

A scientist who explained that as air moves faster, it applies less pressure on its surroundings.

Boyle, Robert

A chemist who described that as the pressure of a gas increases, its volume will decrease.

Curie, Marie

A chemist known for her work on radioactive elements that decompose by nuclear decay.

Franklin, Benjamin

A physicist who identified that there are two kinds of electric charge: positive and negative.

Franklin, Rosalind

A chemist who discovered that DNA has a double helix (twisted ladder) shaped structure.

Herschel, Caroline

An astronomer who explained that telescopes are devices that can locate faraway objects in the night skies.

Joule, James Prescott

A physicist who formulated the principle that energy cannot be created or destroyed, only changed in form.

Julian, Percy

A chemist who defined a chemical change as one in which something new is formed.

Lord Kelvin

A physicist who established that absolute zero is the temperature at which all motion of molecules stops.

Meitner, Lise

A physicist known for her work on nuclear fission, occurring when an atom splits, creating a chain reaction that releases energy.

Morgan, Garrett

An inventor who created the traffic light.

Newton, Isaac

A physicist who explained that objects cool off more rapidly when they are much warmer than their surroundings.

Ohm, Georg Simon

A physicist who stated that the electric current through any circuit is directly proportional to its voltage.

Pascal, Blaise

A physicist who established that the pressure of a fluid on a material decreases with increasing area.

Tesla, Nikola

A physicist who proposed that water can be used to generate alternating electric current.

Volta, Alessandro

A physicist who invented a battery made with a pile of two metals and an acid solution.
