Question

pablo is making a solution. he puts 1 g of sugar into 1 l of water. which kind of change takes place when pablo mixes the sugar and the water? a thermal change a physical change a chemical change an energy change

Explanation:

When sugar is dissolved in water, no new substances are formed. The sugar molecules disperse among water molecules. This is a characteristic of a physical change. A chemical change would involve the formation of new chemical substances. A thermal change relates to heat transfer, and an energy change is a more general term. But the key here is the lack of new - substance formation, which points to a physical change.

Answer:

B. a physical change
