Describe 3 methods to increase the rate of dissolution for sugar in a cup of tea

1. Stirring. This will agitate the sugar and encourage it to dissolve. Stirring creates friction and motion, which in turn will create heat that pulls the sugar particles apart as they are given energy. 

2. Applying heat. As mentioned in the previous method. The application of heat gives extra energy to the sugar molecules which encourages it to pull apart and dissolve. 

3. Increase the surface area. Where more sugar particles are fully submerged in the tea or being surrounded by the tea, the rate of dissolution will increase. 

The answer should be vaporization
