Calculating Specific Heat Capacity: Solving for Unknown Variables

Click For Summary

Homework Help Overview

The discussion revolves around calculating the specific heat capacity of a metal when it is immersed in water, involving the principles of heat transfer and thermal equilibrium. The problem presents specific masses and temperatures for both the metal and water, leading to a query about the unknown variable of the metal's specific heat capacity.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the application of the heat transfer equation Q=mc∆t and the principle that heat gained by the metal equals heat lost by the water. Some participants question the clarity of the attempts presented, while others suggest focusing on the temperature changes involved.

Discussion Status

The discussion is ongoing, with some participants providing guidance on the correct equation to use and prompting further exploration of temperature changes. There is no explicit consensus on the solution, and multiple interpretations of the attempts are being considered.

Contextual Notes

There are indications of typos in the attempts, and the original poster's attempts at solutions are noted as insufficient by other participants. The discussion is framed within the constraints of a homework assignment, emphasizing the need for clarity in reasoning and calculations.

Homework Statement


When 1.25 kg of a cold metal at a temperature
of 263 K was immersed in 1.43 kg of water at
a temperature of 365 K, the final temperature
was 336 K. What is the specific heat capacity
of the metal?

Homework Equations


Q=mc∆t
-Q=Q[/B]

The Attempt at a Solution


The answer should be 1.90KJ(kg*K)[/B]

Heat gained by metal = heat lost by water.

That's not an attempt at a solution.

And there are a couple of typos as well, it should be written as 1.90 kJ/(kgK)

Well, you have the right equation there. How much will the temperatures change?
