Question

1. when sugar is mixed into tea, which property of the sugar stays the same?

Explanation:

When sugar is mixed into tea, it undergoes a physical change. Its chemical composition remains unchanged as it is just dissolving in the liquid. Physical properties like mass and chemical identity stay the same.

Answer:

Chemical composition (assuming mass is not among the options, if mass is an option, mass also stays the same in a closed - system context as no sugar is added or removed during the mixing process)
