![TUTOR Thermal Equilibrium I
Submit
A 34.2 g sample of copper at 99.8 °C is carefully placed into an insulated container containing 205 g of water at 18.5 °C.
Calculate the final temperature when thermal equilibrium is reached.
Assume there is no energy transferred to or from the container.
Specific heat capacities:
Cu = 0.385 Jg¹ °C-1
H₂O = 4.184Jg¹ °C-1

TUTOR STEP
The quantities of energy transferred are equal but opposite in sign so we can use acopper = -water to solve for Tf.
Enter the correct value for Tf.

Incorrect
Rearrange the equation to solve for Tfinal-
Show Hint
The equation looks like:
(0.385 Jg¹ C¹ )(34.2 g) (Tfinal - 99.8 °C) = -(4.184 Jg¹ C¹) (205 g) (Tfinal - 18.5 °C)
