Chapter 19: Problem 2

A quantitative relationship between the energy absorbed and energy emitted by a body was forward by (a) Einstein (b) Kirchhoff (c) Hess (d) Fermi

Short Answer

Expert verified
(b) Kirchhoff

Step by step solution

01

Understand the Question

The question is asking who proposed a quantitative relationship between the energy absorbed and energy emitted by a body. This is related to the principle of energy conservation in physics.
02

Recall the Information

Know that Albert Einstein is famous for the theory of relativity. Gustav Kirchhoff is known for his laws on electrical circuits. Germain Hess introduced the concept of Hess's law in thermochemistry, and Enrico Fermi is recognized for his work on beta decay. Based on the context of the question, we can eliminate Einstein, Kirchhoff, and Fermi.
03

Final Answer

Considering the options and recalling the contributions of these scientists, the answer is (b) Kirchhoff because he proposed the law of thermal radiation, which is a quantitative relationship between the energy absorbed and energy emitted by a body.
