The final temperature of the system containing a sheet of gold and a sheet of iron metal is to be calculated, assuming no heat is lost to the surroundings. Concept Introduction: Heat absorbed or released by a system is calculated by multiplying the mass of the substance with its specific heat and the change in temperature of the system. Sign of heat change is positive, if heat is absorbed by the system, and negative, if heat is released by the system. The heat absorbed by the substance in the given system is calculated by the expression: q = m s ( T 2 − T 1 ) . Here, q is the heat change, m is the mass of substance, s is the specific heat capacity of substance, T 1 is the initial temperature, and T 2 is the final temperature of the system.

Chapter 5, Problem 37QP

Interpretation Introduction

Interpretation:

The final temperature of the system containing a sheet of gold and a sheet of iron metal is to be calculated, assuming no heat is lost to the surroundings.

Concept Introduction:

Heat absorbed or released by a system is calculated by multiplying the mass of the substance with its specific heat and the change in temperature of the system.

Sign of heat change is positive, if heat is absorbed by the system, and negative, if heat is released by the system.

The heat absorbed by the substance in the given system is calculated by the expression: q=ms(T2−T1).

Here, q is the heat change, m is the mass of substance, s is the specific heat capacity of substance, T1 is the initial temperature, and T2 is the final temperature of the system.
