electronic heat sensors to record body temperature‚ can be used in the rectum‚ mouth or armpit. The most accurate way to take a child’s temperature is to use a digital thermometer‚ either rectally or orally. Rectal temperatures provide the best readings for infants‚ especially those 3 months or younger as well as children up to age 3. If you use another type of thermometer to take a young child’s temperature and you’re in doubt about the results‚ take a rectal temperature. For older children and adults‚

Understand and observe the concept of Heat Transfer‚ by measuring the temperature distribution for steady state conduction of energy through a specific efficient unit. • Understand the Fourier Law of heat conduction and the usage of its equation in determining the rate of heat flow via solid materials. II. Theory : The Fourier Rate Equation: When a plane section of ∆x and a constant area A maintains a temperature difference ∆T‚ then the heat transfer rate per unit time by conduction

I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties

variance in final temperature for each experiment was less than 10 percent providing proof of repeatability. Equipment used during the experiment included a gram scale‚ thermocouple‚ Styrofoam cup‚ glass beakers‚ microwave‚ an ice bath and ice. The first half of the experiment was dedicated to the mixing of two containers of water at different temperatures. The mass of the water in each container was measured and the containers were then heated or cooled to achieve the temperature desired for the experiment

Abstract The glass transition temperature of polymethylmethacrylate ( PMMA‚ Perspex) is measured using static and dynamic method while the glass transition temperature of rubber of different size is measured using only dynamic method. The glass transition temperature Tg of Perspex is found to be 90°C using the static method and 160°c using the dynamic method. On the other hand‚ the Tg of rubber is found to be -30°C. Introduction Perspex is a type of amorphous polymer and has the following

Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine the

measure the enthalpy (H) of a chemical reaction. The main obstacle is that this is a quantity that cannot be measured directly. It instead is observed as heat from one substance is transferred to another while being monitored with a thermometer.
