State whether the entropy of the system increases or decreases and why, and whether the entropy of the surroundings increases or decreases and why:
a) system: a block of ice in a box at a temperature below freezing. the block of ice does not completely fill the box and the unfilled volume is vacuum. the box is not insulated. the change occurs when the block loses water molecules from its surface to form a low-pressure vapor in the unfilled volume of the box.
b) system: two h2 molecules and one o2 molecule in the gas phase. the change occurs when the h2 and o2 molecules react with each other to form two h2o molecules.
c) system: a lipid bilayer membrane in an aqueous solution with glucose molecules at 0.1 m concentration on one side and 0.01 m concentration on the other side. the change occurs when the glucose molecules on the low concentration side move to the high concentration side.
state whether the entropy of the system increases or decreases and whether the entropy of the surroundings increases or decreases and explain why. i haven't studied this information in a while and need to brush up! for your time!
