1. Do all cold drinks reach room temperature at the same amount of time? Chan Yuet Huey Josephine, Su Hang, William Goh M07107 Dr. Ng Kai Ling In Singapore’s tropical climate, cold drinks are favourites of all the people sweating under the sun. People being under such an inferno would certainly want a cold drink that will stay cold for a long time. Therefore, we have decided to come up with an experiment to see which cold drink is the best to enjoy on a hot, sunny day! Introduction What we are looking for in this project is the heat capacity of some of the popular drinks in this hot country, Singapore. Heat capacity is basically a measure of how well a substance stores heat or the amount of heat required to raise the temperature of one unit of a substance by one unit of temperature. Results and Discussion It is evident that Sprite has the gains the least amount of heat, therefore, Sprite has the highest heat capacity. Hypothesis Not all cold drinks reach room temperature at the same time. • Method & Materials • Materials needed: • Coke • Sprite • Mango juice • Ice Lemon tea • Green tea • Bottled water • Measuring cylinder • 18 200ml plastic cups • 3 digital thermometers • 3 stopwatches • Steps: • 1 Put all drinks in the fridge with the same temperature. • 2 After chilling all the drinks, measure the room temperature of the surrounding are which the experiment is conducted, and take out the drinks. • 3 Measure out 200ml of each drink in the measuring cylinder and pour out into the plastic cups. • 4 Measure the starting temperature of all the drinks at the start of the experiment. • 5 Measure the temperature of the drinks at intervals of 15 min. Record data in data tables. • 6 Repeat for Trials 2 and Trial 3. Conclusion Sprite is the best drink to drink on a hot, sunny day, as it gains the least heat in a specific amount of time compared to others of the same volume.
