Scenario You have a new job working as designer for a new theme park. You have been tasked with designing two new attractions - one must be a go kart racetrack,

and the other must be a food stand that serves fresh donuts, candy floss and sweets. Question 1 - Food stand (AC2.1, 2.2, 2.3, 4.1 & 4.2) You need to choose the correct oil for the donut fryer (power of the fryer is 2000W). The oil has plenty of time to heat up before opening, and you need it to stay as hot as possible to reduce the energy consumption when keeping the oil hot all day. You design an experiment to calculate the specific heat capacities of the oil. a) You decide to run your experiment for 5 minutes. Your results are in the table below. Use them to calculate the specific heat capacity of each oil, then choose an oil for your fryer based on these results. Mass (kg) 2.3kg 2.1kg 3.2 kg Oil type Corn oil Vegetable oil Lard b) You realise that lard is solid when you take it out of the fridge. You decide to run an experiment starting from solid state. 250 200 150 100 50 Temperature at the start (°C) 40 40 40 The graph of your results is below. Describe what is happening at each section of the graph. Then use this to calculate the total energy needed to heat 3.2kg of lard at 3°C out of the fridge to frying temperature of 200°C. The latent heat of fusion of lard is 60kJkg-¹ The specific heat capacity of lard when solid is 1.3kJkg-¹°C-¹ Lard Heating Graph 0 10 20 Time (minutes) 30 Temperature at the end (°C) 182 211 123 40 50/nc) One of the bestselling items at the stall are gummy worms, so you decide to perfect the recipe. The ideal gummy will stretch a little as you bite into it, but not too much. The mold you use produces worms with a length of 0.1m and a diameter of 0.03m. You narrow it down to two recipes. In the graph below are the two possible options you produce when you hang weights from the bottom of your two most likely gummy worms and measure the extension. Force (N) 4 6.4 Extension (cm) Calculate the Young Modulus of the gummy worms by converting one of the options into a stress/ strain graph (to be shown with your answers) and the other by using calculations. Choose which gummy worm you think would be better and explain why.
