Answer:

1. The stirring allows fresh solvent molecules to continually be in contact with the solute. If it is not stirred, then the water right at the surface of the solute becomes saturated with dissolved sugar molecules, meaning that it is more difficult for additional solute to dissolve.

2. Hot water is a vasodilator, meaning it expands the blood vessels, improving circulation. This can help muscles relax and reduce pain. Although no studies have directly linked hot water to sustained improvements in circulation, even brief improvements in circulation can support better blood flow to muscles and organs.
