19Imagine a thick ten-kilogram block of soap and a thin ten-kilogram sheet of soap. Which answer correctly explains which will dissolve first when they are both placed underwater?The sheet will dissolve first because it has more surface area.The sheet will dissolve first because it has less mass than the block.The block will dissolve first because it is less spread out than the sheet.D. The sheet and the block weigh the same, so they will take the same amount of time to dissolve.
20Kayla wants to know if a sugar cube in a bowl of water will dissolve more quickly if it is stirred with a spoon than if it is left alone. Which answer explains the effect that stirring will have?Stirring makes the sugar move around, and it dissolves more slowly because it is not staying still.The sugar will dissolve more slowly because the movement of the water makes it stick together.The sugar dissolves more quickly because the motion of the spoon creates heat, which melts the sugar.D. When the sugar is stirred, more surface area will come into contact with the water, so the sugar dissolves more quickly.
