History

Question 1

Antoine Lavoisier

Answer 1

When equal amounts of different substances burned, the chemical reactions could produce different amounts of heat

Question 2

Chemical energy

Answer 2

Potential energy stored in chemical bonds of compounds

Question 3

Electrical energy

Answer 3

Work by moving charges

Question 4

Alessandro Volta

Answer 4

Invented Volta pile, an apparatus of stacked layers that acts as a source so a constant electrical current can go through it

Question 5

Hab Oersted

Answer 5

Discovered an electrical current in a wire could produce magnetic effects (danish scientist)

Question 6

Faraday

Answer 6

Magnetism could result in electricity

Question 7

Thomas seebek

Answer 7

Demonstrated heat could be turned into electricity and that could create a magnetic field

Question 8

Thomas Edison

Answer 8

Invented light bulb, heat and light can be produced from electricity

Question 9

Henri Becquerel

Answer 9

Atoms spontaneously disintegrate and in the process emit radiation or radiant energy

Question 10

Nuclear energy

Answer 10

Potential energy stored in the nucleus of an atom, also released in nuclear fission(nucleus is split) or fusion (nuclei combine)

Question 11

Solar energy

Answer 11

Results from hydrogen nuclear Fugen reaction with the release of nuclear energy

Question 12

How does radiant energy travel to earth

Answer 12

Electromagnetic radiation

Question 13

Gottfried Leibniz

Answer 13

Posited a physical quantity vis a viva living force SEARCH HIM UP

Question 14

What wasn’t used till the 1850s

Answer 14

‘Energy’

Question 15

Mechanical energy

Answer 15

The sum of the energy of motion and position

Question 16

Atomists

Answer 16

Thought that heat was somehow related to the motion of ‘atoms’ or tiny particles within a substance

Question 17

Joseph black

Answer 17

Propose that heat was an invisible fluid, he’s cracked at thermodynamics.

Question 18

Benjamin Thompson

Answer 18

Minister of war in Bavaria, count rumford; heat and mechanical energy had to be related

Question 19

Thomas Young

Answer 19

Mechanical energy combined both kinetic and potential energy

Question 20

Energy

Answer 20

Capacity to work

Question 21

Sadi Carnot

Answer 21

Experimented to trnsform heat to mechanical energy, discovered some heat is always lost and transformation could only occur when thermal energy flows from a hot object to a cool object

Answer 22

Substitutes the term energy vis viva ( search up)

Question 23

1840

Answer 23

Largely accepted that heat was not a physical substance
