Answer:
The entropy change for the change of state is 0.1091 kJ/K.
Step-by-step explanation:
The entropy change for a change of state can be calculated using the formula:
ΔS = q / T
where q is the heat absorbed by the substance, and T is the temperature at which the change of state occurs. In this case, the heat absorbed by one mole of water is 40.7 kJ, and the temperature at which the change of state occurs is 100°C.
To convert the temperature from degrees Celsius to kelvins, we need to add 273 to the temperature in degrees Celsius. This means that the temperature in kelvins is 100°C + 273 = 373 K.
Using the formula above, we can calculate the entropy change for the change of state as follows:
ΔS = 40.7 kJ / 373 K = 0.1091 kJ/K
Therefore, the entropy change for the change of state is 0.1091 kJ/K.
