when a 140g piece of metal at 70 degree Celsius is placed in 220g of water at 0 degree Celsius, the metal is cooled, and the water is warmed and both come to a final temperature of 10 degree Celsius. What is the specific heat of the metal?

Best ResponseYou've already chosen the best response.1you set the two equal to each other and solve for c. That equation will give units of Joule/(gram Celsius)

Best ResponseYou've already chosen the best response.0so would i be solving the equation that you suggested i'm confused

Best ResponseYou've already chosen the best response.1ok we have the equation Q=mc(dT) where Q is heat, m is mass of whatever is changing temperature, dT is the change in Temperature.

Best ResponseYou've already chosen the best response.1the magnitude of the heat has to be the same for both the metal and the water

Best ResponseYou've already chosen the best response.1so you plug the known values into the heat equation for water and metal and set them equal to each other to find the specific heat you are looking for.

Best ResponseYou've already chosen the best response.1The magnitude of the heat is the same in both due to conservation of energy

Best ResponseYou've already chosen the best response.0so basically what would be the numbers in the equation to plug into the problem if is the same.

Best ResponseYou've already chosen the best response.1Your final equation would look like: 140*c*(7010)=220*4.186*(100) 140*60*c=220*10*4.186

Best ResponseYou've already chosen the best response.0so what units should i use for this problem?

rsvitale

Best ResponseYou've already chosen the best response.1that c is J/(gC) or Joules per gram degree Celsius

rsvitale

Best ResponseYou've already chosen the best response.0so would this be the same as 1.0963 cal/g degree Celsius ?

rsvitale

Best ResponseYou've already chosen the best response.0like should it say 0.2619 cal/g degrees Celsius, does that sound right?

rsvitale
