It is a chemical change. Table Sugar is the crystallized form of liquid Sucrose(also simply known as, Sugar.)

Is dissolving sugar in hot tea an example of a chemical change?
No, dissolving sugar in hot tea is a physical change, not a chemical change. The sugar molecules are still present in the tea and can be separated by processes like evaporation. The chemical composition of the sugar does not change during the dissolving process.
