How Does the Viscosity of a Liquid Change with Temperature

Viscosity is a measure of a fluid’s resistance to flow when acted upon by an external force such as a pressure differential or gravity. Viscosity is a general property of all fluids, which includes both liquids and gases. It describes the internal friction of a moving fluid. A fluid with large viscosity resists motion because… View Article

Thermal Equilibrium

Thermal Equilibrium If you want to know the temperature of a cup of hot coffee, you stick a thermometer in the coffee. As the two interact, the thermometer becomes hotter and the coffee cools off a little. After the thermometer settles down to a steady value, you read the temperature. The system has reached an… View Article

Physics Online Course

1-How can you demonstrate that water is denser than ice without weighing them? What is the principle involved? Release an ice cube in water; the ice cube will float. The ice cube will displace some water as it “pushes” the water away. The principle involved is displacement. 2-The density of water is a maximum at… View Article

Heat Transfer

Heat transfer, also known as heat flow, heat exchange, or simply heat, is the transfer of thermal energy from one region of matter or a physical system to another. When an object is at a different temperature from its surroundings, heat transfer occurs so that the body and the surroundings reach the same temperature at… View Article

Physical Properties of Various Types of Bricks

Clay bricks are used in a wide range of buildings from housing to factories, and in the construction of tunnels, waterways, bridges etc. Their properties vary according to the purpose for which they are intended, but clays have provided the basic material of construction for centuries. Brick is the oldest manufactured building material, and much… View Article

Ti Chemical Reaction In Automobiles

There are over one billion of cars around the world, getting people where they want to go. Therefore, automobile transportation became much more important in everyone’s daily life. Chemistry made the automobiles to work. The chemistry and chemical reactions used in many parts of the automobiles. The role of chemistry in the automobile includes air… View Article

Enthalpy of Reaction and Hess’s Law

I. Purpose The purpose of this lab is to verify Hess’s Law through the three reactions of NaOH and HCl, NH4Cl and NaOH, and NH3 and HCl. The sum of the enthalpies of the first two reactions should equal the enthalpy of the third reaction. II. Background Hess’s Law is used to determine the enthalpy… View Article

Experiment Report

Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms, the measure of the level of disorder in a closed but changing… View Article

Heat and Iron

A clothing iron, also called a flatiron or simply an iron, is a small appliance: a handheld piece of equipment with a flat, roughly triangular surface that, when heated, is used to press clothes to remove creases. It is named for the metal of which the device is commonly made, and the use of it… View Article

Heat Detector

When present, humans can be excellent fire detectors. The healthy person is able to sense multiple aspects of a fire including the heat, flames, smoke, and odors. For this reason, most fire alarm systems are designed with one or more manual alarm activation devices to be used by the person who discovers a fire. Unfortunately,… View Article

Heat Transfer and Temperature

Question 1: A 50 mm diameter, thin wall metal pipe covered by 25 mm thick layer of insulation (ki = 0.085 W/m.K) and carrying a superheated steam at atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC, and the air temperature is 20 oC…. View Article

Principles of Distillation

What is distillation? Simply, distillation is the process in which a liquid is vaporized (turned to steam), recondensed (turned back into a liquid) and collected in a container. Nature uses a form of distillation to turn salt water (seawater) into fresh water (rain). Why do you use distillation to recycle waste solvents? Solvent-based waste contains… View Article

Balloons Paper

Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more than the weight. Buoyancy occurs because the hot air has a lower density than the cooler outside air. This lower density air weighs less than the air it… View Article

Determination of Heat of Solution

ABSTRACT Thermodynamic values can be determined using the Vant Hoff isochore method. This method entails the use of equilibrium systems to determine the change in enthalpy of the solution, which can b related to the change in internal energy of the solution. The van’t Hoff isochore relates the equilibrium constant of a chemical reaction at… View Article
