PLEASE HELP! A piece of metal is heated to a temperature of 50.0°C and then placed in a calorimeter containing 50.0 g of water at 27.0°C. The water temperature increases to 35.0°C. How many joules of heat were transferred from the metal to the water? (Cwater = 4.18J/g•°C)

1672 Joules

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed by water = ?  

c = heat capacity of water =

Initial temperature of the water = =

Final temperature of the water  =  =

Change in temperature ,

Putting in the values, we get:

As heat absorbed by water is equal to the heat released by metal, the Joules of heat transferred are 1672 Joules
