Which of the following processes is associated with a positive change in entropy?

Which of the following processes is associated with a positive change in entropy?

Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Identify the process in the question. The process mentioned is the sublimation of dry ice (solid CO2) to gas.
Step 3: Recognize what happens during sublimation. Sublimation is when a solid turns directly into a gas without becoming a liquid first.
Step 4: Consider the state change. When dry ice sublimates, it goes from a solid (which is more ordered) to a gas (which is more disordered).
Step 5: Conclude the effect on entropy. Since the gas state has more disorder than the solid state, this results in a positive change in entropy.
