Question

A 508−g piece of copper tubing is heated to 89.5°C and placed in an insulated vessel containing 159 g of water at 22.8°C. Assuming no loss of water and a heat capacity for the vessel of 10.0 J/°C, what is the final temperature of the system (c of copper = 0.387 J/g·°C)?

Answer 1

Teq=37.85°C

Step-by-step explanation:

Hello, I'm attaching a picture in which the mathematical procedure is given.

- the specific heat of water was extracted from Cengel's thermodynamics book.

- take into account that since the system is isolated, no dissipation or absorption of energy is presented.

- we assume that the initial temperature of the vessel is equal to the water's initial temperature.

- the symbolic T is the very same temperature when the equilibrium is reached.

Best regards.
