What’s the matter?

Saturday 12 January 2019

This week, we tested which materials are soluble and insoluble. We sorted sand, salt, sugar and many more into these two groups.

After that, we investigated if the temperature of water affects the speed of dissolving. We had to test this several times to make sure our results were reliable. Then we calculated the mean time taken for sugar to dissolve in different temperatures.

Our results showed us that the higher the temperature of water, the faster the sugar dissolves. Therefore, the temperature of water does affect the speed of dissolving. I wonder why? Can you find out?
