If a geiger counter that is 1 m away from a small source reads 50 counts per minute, what will its reading be 2 m from the source?

Explanation:

Hello,

In this case, the radiation from a point source follows an inverse-square law wherein the quantity of radiation is proportional to 1/d², where d is distance. Therefore, 2 m away from the source, the counts will be:

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
