A 38.1 g sample of a metal is heated to 85.3 °C and placed into coffee cup calorimeter containing 125 g of water initially at 25.0 °C. After the temperature of the water and the metal stop changing, both are found to have a final temperature of 26.7 °C. What is the specific heat of the metal in J/(g·°C)?
any idea how many Joules "went into" the water ?
Would it be 125 * 4.18 * (26.4-25) = 888.25 Joules
Please help me :(
yes, that looks good, except you should use 26.7 (not 26.4). but 888.25 is good you have 38.1 g * (85.3 - 26.7)* x = 888.25 solve for x to get the specific heat of the metal
I get about 0.398 J/(g-K)
Thanks :D
Wait, do you mean (g-C), not (g-K)
@phi
Kelvin and C are the same sized units , but K starts at absolute zero. you can use either
Ok, thanks!
