A 30. g sample of Aluminum was heated to 40. 0C and placed in a calorimeter containing 50. g of water at 21 0C. What is the final temperature of the aluminum-water system if the cAl = 0.21 cal/g0C and cwater = 1.0 cal/ g 0C. Write the complete equation you will use. 1 point

Substitute the values in the equation in step 1 . 1 point

Report the math answer with 2 sig figs and the correct unit. 1 point

The final temperature will be

Explanation:

Calculating the heat released or absorbed for the process:

In a system, the total amount of heat released is equal to the total amount of heat absorbed.

    OR

          ......(1)

where,

= specific heat of aluminium =

= heat capacity of water =

= mass of aluminium = 30. g

= mass of water = 50. g

= final temperature of the system = ?

= initial temperature of aluminium =

= initial temperature of the water =

Putting values in equation 1, we get:

Hence, the final temperature will be
