## Conclusion

As can be seen from Figures 1-4 on the previous page, there was a directly proportional relationship between the darkness of the glasses and the rate at which heat was absorbed.

From Figures 1 and 3, we can see that after 15 minutes, there was a 0.8°C difference in the temperature of water. This is equivalent to a difference of 9%, over just 15 minutes. Similarly from figures 2 and 4, we see a difference of 5 minutes to increase the temperature by 2°C, a speed gain of 33.3%, when using darker colours.

These results support the hypothesis, put forward at the beginning of the investigation; that the darker the shade of glass, the greater rate at which heat is absorbed by it.
