Video transcript

Hello everyone in this video want to identify the parameter that entropy measures. So entropy you let's recall what the definition is. Entropy is the degree of chaos or disorder or randomness in a system and it's dependent on things such as the face complexity and size or mass of the molecule. All right, so taking a look at these answer choices here, we have heat transferred from the system to the surroundings, energy of the universe, total energy of a system and degree of randomness. So based on this definition here, we know that it's based on the randomness. So my final answer then, of course, going to be statement D here, which is the degree of randomness of a system.
