Question

Agitation, temperature, and surface area of the dissolving particles determine how fast the substance will dissolve. Using these three factors, describe how you can increase the rate of sugar dissolving in a cup of tea.

Answer 1

Agitation, temperature, and surface area of the dissolving particles determine how fast the substance will dissolve.

to increase the rate of sugar dissolving in a cup of tea:

Agitation - by stirring w a spoon, the sugar solid will be agitated n dissolve faster in tea.

temperature - by heating the tea, the sugar will dissolve faster in tea.

surface area of dissolving particles - by using granular sugar instead of sugar cube, the contact surface area w tea is increased. granular sugar will dissolve faster in tea.

Answer 2

You may not be able to see the sugar you've stirred into your tea, coffee or hot chocolate, but it's still there. Rather than disappearing completely, it dissolves. When a solute is dissolved in another substance, a solution is created. So when you prepare your hot beverage, the sugar is the solute, the water is the substance and the finished product is the solution. Working out how to dissolve sugar faster involves some interesting experiments that you can easily carry out at home with sugar cubes and cups of water.
