22) A thermometer is removed from a beaker of boiling water and placed in a beaker of room temperature water. The
thermometer takes 15 seconds to reach a reading of 25°C. The same thermometer is returned to the boiling water
for several minutes. It is then placed under a tap of running water at room temperature.
The thermometer takes
only 10 seconds to reach a reading of 25°C.
What conclusion could you make about conduction and convection based on these observations?
A)
Conduction is a more efficient method of heat transfer.
B)
Convection is a more efficient method of heat transfer.
C)
No valid clusion is suggested by these observations.
D)
Conduction and convection are equally efficient methods of heat transfer.

Answer c

it is the most commonly accepted one

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.
