Question

1) In 1783 Antoine Lavoisier showed that the heat produced by respiration was comparable to the heat produced when charcoal was burned. This experiment shows the similarity between respiration and A) boiling. Eliminate B) combustion. C) ignition. D) melting.

Answer 1

The correct answer is B combustion.

Lavoisier’s oxygen theory of combustion was one of his most notable contribution to science and earned him the title of the “father of modern chemistry”. He recognized the combustible property of oxygen and that phosphorus and other metallic elements increased in terms of weight when burned.  

Answer 2

Answer:

The correct answer B) "combustion".

Explanation:

Respiration and combustion share the similarity that both processes release energy in the form of heat. In respiration, heat energy is released as glucose burns, while in combustion heat energy is released when an hydrocarbon (such as charcoal) or other organic molecule reacts with oxygen and gets burned. In 1783 Antoine Lavoisier showed this similarity in his laboratory.
