Question 3 (Heat and Thermodynamics) - CO3, PO1, C3 [Total Marks: 5 Marks] A student wishes to determine the specific heat of a new metal alloy. A 0.2 kg sample of the alloy is heated to 540 °C. It is then quickly placed in 0.4 kg of water at 10 °C. After 20 seconds, the calorimeter detected that the alloy releases 2000 J of energy to the water, and the alloy temperature decreased to 490 °C. a) Calculate the specific heat capacity of the alloy (in J/kg°C). b) Find the expected increase of temperature of the water (specific heat capacity of water = 4182 J/kg°C). c) Estimate the rate of heat transfer from the metal alloy to the water
