Chapter 6, Problem 6.44P
Interpretation Introduction

Interpretation:

The unknown volume of water at 18.2°C that is added to 24.4 mL of water at 35.0°C to get the final temperature 23.5°C is to be calculated.

Concept introduction:

Specific heat capacity (c) of a substance is the amount of heat needed to raise the temperature of 1g of a substance by 1K. The formula to calculate heat required is as follows:

q=(mass)(c)(ΔT)        (1)

Here,

ΔT is the temperature difference.

q is the heat released or absorbed.

c is the specific heat capacity of the substance.

The formula to calculate the mass of a substance is as follows:

mass=(density)(volume)        (2)
