Homework Soursethis is the formula given in my textbook where C is degreesc
this is the formula given in my textbook, where C is degreescelsius, and x indicates multiplication:
heat(J)=specific heat(J/kgxC) x mass(kg) x change intemperature (C)
heat(J)=specific heat(J/kgxC) x mass(kg) x change intemperature (C)
The problem given to solve is: A student heated a emtal objectweighing 40.0 grams to 100C. She placed this metal into acalorimeter which contained 175g of water at 20.0C. Themaximum temperature that the water and metal in teh calorimeterreached was 22.2C. What is the specific heat of the metal?
I thought I had solved the problem, but then realized I didn\'tknow what to do with the J/kgxC part of the equation. I hadplugged in to the equation as follows: 100C = Spec.Heat x .004kg x2.2 = 100/.0088=113636.36 This must be completelywrong! All the other metals on the chart shown in the textbook range from 128(lead) to 448(iron). Please help! Thank you
