The density of a penny is higher.
Yes, the amount of soap mixed with water can affect how well the water will stay on a penny. Soap reduces the surface tension of water, causing it to spread out more easily. Too much soap can prevent the water from forming a cohesive layer on the penny, causing it to bead up or slide off.
When you place regular water on a penny, surface tension allows you to fit about 15-20 drops before it overflows. However, when you add soap to the water, the surface tension decreases, allowing more water to spread out rather than bead up. As a result, you can typically fit around 10-15 drops of soapy water on the penny, demonstrating the effect of soap on water's surface properties.
Hot water will dissolve soap faster because it is more hot so that means it will melt is and also evaporate with the water.
The scum around the sink could be caused by hard water minerals like calcium and magnesium. When soap is used in hard water, it reacts with these minerals to form soap scum. Using a water softener or vinegar can help reduce the formation of scum.
Yes, the amount of soapy water can affect how many drops fit on a penny. More soap can reduce the surface tension of the water, allowing it to spread and form a flatter shape, which may result in fewer drops fitting on the penny. Conversely, less soap increases surface tension, potentially allowing more drops to fit. Therefore, the concentration of soap in the water plays a significant role in this experiment.
Well it really depends on what type of soap you're using
The process of adding dish soap to water in a sink is a physical change.

Dish soap works by breaking down the grease and oil that coats the penny, making it easier to rinse away. The soap molecules also surround and lift away dirt and grime, allowing them to be washed off with water. This helps the water and soap mixture to penetrate and clean the surface of the penny effectively.
Dish soap is more effective at cleaning a penny than water alone. Dish soap can break down oils and dirt on the surface of the penny, allowing for a more thorough cleaning compared to just using water.

Dish soap generally floats on water due to its lower density compared to water. This is because dish soap is less dense than water, causing it to float.
Dawn dish soap is effective at cleaning a penny due to its ability to break down fats and oils. The soap molecules surround greasy residues on the penny, allowing them to be washed away with water. Additionally, the surfactants in Dawn help to reduce the surface tension of water, making it easier to remove dirt and grime from the penny.
M&Ms dissolve faster in water than in soap because water has a higher solubility for sugar compared to soap. Soap molecules are more attracted to fats and oils, making them less effective at dissolving sugar.
Soap reduces the surface tension of the water, making it easier for the water to overcome the buoyancy force of the paper clip, causing it to sink. This is because the soap molecules disrupt the cohesive forces between water molecules, allowing the water to spread out more easily and envelop the paper clip.
because it does.
No, adding dish soap to water in a sink is not considered a chemical change. It is a physical change because the substances involved do not undergo a chemical reaction to form new substances.
