(a)

Summary Introduction

Introduction: Osmolarity refers to the number of particles in solution. It is a property of every solution, and a person can be compared with the osmolarities of different solutions as long as with the concentrations that are expressed in the same units.

(b)

Summary Introduction

To determine: Whether the cell volume of the body will decrease or increase or remain unchanged after sweat loss.

Introduction: The term tonicity is used to describe a solution and how that solution would affect the cell volume.

(c)

Summary Introduction

To determine: The volume and osmolarity of the cell after the sweat loss.

Introduction: Osmolarity describes the number of osmotically active particles (ions or molecules) per liter of solution. It is expressed in osmoles per liter or for very dilute solutions, milliosmoles per liter.

Summary Introduction

To determine: Whether the result for change in cell volume and osmolarity of the body matches with the above answers.

Introduction: Osmolarity and cell volume are interrelated. If the osmolarity of the cell increases, there is loss of water from the cell which decreases the cell volume.
