Finding the Heat Capacity of a Metal Using Constant Pressure Calorimetry

Click For Summary

Discussion Overview

The discussion revolves around a homework problem involving constant pressure calorimetry to determine the mass of water that can be heated by a metal pellet. The participants explore the relationship between the heat transfer from the metal to the water and the unknown heat capacity of the metal.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant states the formula for heat transfer, indicating that the heat gained by the water equals the heat lost by the metal.
  • Another participant suggests that the problem may be part of a lab procedure to find the heat capacity of an unknown metal, but notes the necessity of knowing the mass of water.
  • A third participant clarifies that the problem is from a textbook, implying it may be a standard exercise.
  • Another participant emphasizes that without the heat capacity of the metal, the question cannot be solved and questions whether all necessary information has been provided, asking about the metal's properties or a reference table for heat capacities.

Areas of Agreement / Disagreement

Participants generally agree that the heat capacity of the metal is essential for solving the problem, but there is uncertainty regarding whether all relevant information has been provided.

Contextual Notes

Participants note the potential missing information about the metal, such as its molar mass or a reference table for heat capacities, which could affect the ability to solve the problem.

Homework Statement


what mass of water could be warmed from 23.8 C to 46.3 C by a 100 g metal pellet at
116 C

Homework Equations


The Attempt at a Solution


well i know the formula qsurr=ms\DeltaT
so qwater=ms\DeltaT

but then how do i work my way around when the heat capacity isn't also given
i'll really appreciate all the help i can get.

Is this for a lab? I would imagine that such a procedure is utilized to find the heat capacity of an unknown metal however for this you would need the mass of water.
 
no its actually a problem in the book
 
Without metal heat capacity question has no solution. But I doubt you gave us all information regarding the question. Are you given any information about the metal? Molar mass? Is there a table with heat capacities of various metals somewhere in the book?
