Title: Need help with this Calorimetry problem
Post by: yolomite on September 22, 2019, 11:37:36 PM

A 25.0 g sample of an alloy was heated to 100.0 o C and dropped into a beaker containing
90 grams of water at 25.32 o C. The temperature of the water rose to a final value of 27.18
o C. Neglecting heat losses to the room and the heat capacity of the beaker itself, what is
the specific heat of the alloy?

How do I solve this problem? Am I supposed to have to variables because I do not know the intial temperature of the water. I only have the final.

What about the 25.32 °C

Assume specific heat capacity to be an unknown x, use it to express what you know about the system with equations, solve for the unknown.
