Acalorimeter contains 195 g of water at 20.4 º c. a 37.8 g sample of an unknown metal is heated to 133 º c and placed into the water in the calorimeter. the final temperature of the metal and the water are 24.6 º c. what is the specific heat of the metal?

heat loss by the sample=heat gain by the water

Q=mass(kg)*Specific heat* Change in temperature

  =m*c*Change in T

0.0378*c*(24.6-133)*(-1)=0.195*4186*(24.6-20.4)

c=(0.195*4186*4.2)/(0.0378*(133-24.6))

 =836.7 J/(kg*Celsius degree)

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.
