Will this entropy change by positive or negative?
If the system becomes more disordered, the entropy change will be positive. If the system becomes more ordered, the entropy change will be negative.
Will this entropy change by positive or negative air is pumped into a tire?
entropy is decreasing, so negative
Will this entropy change by positive or negative n2 g 3h2 g 2nh3 g?
negative
Predict whether the changes in enthalpy entropy and free energy will be positive or negative for the freezing of water and explain your predictions How does temperature affect the spontaneity?
The changes in enthalpy, entropy, and free energy are negative for the freezing of water since energy is released as heat during the process. At lower temperatures, the freezing of water is more spontaneous as the negative change in enthalpy dominates over the positive change in entropy, making the overall change in free energy negative and leading to a spontaneous process.
When water freezes should the change in entropy be positive or negative and explain?
When water freezes, the change in entropy is negative. This is because in the process of freezing, the molecules become more ordered and arranged into a crystalline structure, leading to a decrease in randomness and disorder in the system. This decrease in disorder corresponds to a decrease in entropy.
