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

If I have 2.4 kg of Silver that I need to melt at the melting point , how much heat needs to be added? (Lf for Silver :88,300) Answer in Joules answer in standard form
In the calculating of heat transferred in calorimeters, why is it that the equilibrium temperature is the one recorded and not the initial temperature? Why is it that if initial temperatures are the one used it would end up inaccurate and invalid? Please guide me in answering this. I am writing for my school newsletter's science monthly corner. Thank you in advance.

QUESTION 3 A dead body was found within a closed room of a house where the temperature was a constant 66 °F. At the time of discovery, the core temperature of the body wasdetermined to be 88 ° F. One hour later a second measurement showed that the core temperature of the body was 77 ° F. Assume that the time of death corresponds to t = 0 and that the core temperature at that time was 98.6 ° F. Determine how many hours elapsed before the body was found. Type your answer in hours in the space provided below. Round your answer to one decimal place.
