5. Conclusion


 As we were using an induction cooker to heat the water, the heating graph was not consistent as the temperature was always varying. The induction coil was turned on and off overtime automatically to prevent it from damaging itself. Even at the highest setting, the coil was turn off at least 10% of the time. Thus, we got a not so smooth graph. As for the cooling part, the sensor node might be in contact with the cold metal side of the mug, and the temperature recorded might be lower as the mug was in direct contact the nitrogen.

Practical Applications

 Although this experiment might seem simple, everyday cooking can be adjusted. The boiling temperature of water can be increased by a bit with a pinch of salt, although the difference is very small, your food will be cooked at a slightly higher rate. As for the freezing part, when you are trying to to ice cool to chill your drinks down, add in a some salt, as it raises the melting point, which means the ice cubes will remain cool longer, allowing you to chill your drinks faster.

Areas for further study

 Instead of just working with water with dissolved impurities, we could worked with other liquids such as vinegar. We could have used better equipment to make the results more consistent. The results could be much different than compared to water. Other common chemicals could be used, but we would not know if these chemicals will react violently when heated to boil or when chilled to extreme temperatures.
