Please help me with the following Physics Lab questions.

Specific Heat Measure the specific heat of a metal Step 1: Determine the mass of the metal sample: mmetal = Step 2: Weigh the (dry) empty cup: mcup = Step 3: Fill the cup with cold water enough so that your sample should submerge, find mass of the cup plus water: mcup+w = Step 3: Calculate the mass of water: mw= g Step 4: Record the temperature of the water in the cup: Twi= C Step 5: Record the temperature of the boiling water, which is also the initial temperature of the metal sample that is immersed in it: Tmetal i = .C Step 6: Quickly transfer the metal sample into the cup. Cover the cup and stir the water for a few minutes. Record the highest temperature to which the water rises: Tf = .C Analysis: Since the heat gained by the water is equal to the heat lost by the metal, so: mwowATw + mmetalCmetalATmetal = 0 or mwcw(Tr- Twi) + mmetalCmetal(Tr- Tmetal.i) = 0 (1) specific heat of water cw = 1.0 cal/goC Use the information above to solve eq. (1) for the specific heat of the metal. Show all your work below:Specific heat for metal measured experimentally: Cmetal cal/gc Convert this value of the specific heat into J/kg"C. Show all your work below. (1 cal = 4.186 J) (1 kg = 1000 g) Cmetal = J/kg.C Look up the table of specific heat for different materials in the textbook and find out what metal is the sample made of. The metal is Actual value for specific heat for metal is: Cmetal = J/kg.C Calculate the percent error for your experiment: % error = What are the sources of error in the experiment? Cold or Hot if your house temperature is set at 70 F, the temperature of the tiles floor in the bathroom is the same as the temperature of the rug in your living room (both are at 70.F). Why do bare feet feel colder on a tile floor than on a rug? Answer: Question: You can take off your shirt when it is 10"C but you can't swim in water with the same temperature, you can't stand it, why
