What happens when Ivory soap is microwaved and why? Bonus: Which law is it an example of?
The gas that’s increasing is water vapor. There is whipped air in ivory soap (which is what makes it float). The air contains water, the water gets heated up and turned into water vapor, a gas. According to Charles law, the water vapor needs to expand how much space it takes up when the temp goes up.
