Aglass of cold milk sometimes forms a coat of water on the outside of the glass (often referred to as 'sweat'). how does most of the water get there? a) water molecules from the air condense onto the outside of the glass. b) water molecules from the milk pass through the glass and condense on the outside of the glass. c) water molecules evaporate from the milk and condense on the outside of the glass. d) the coldness causes oxygen and hydrogen from the air to combine on the glass forming water.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
