piece of equipment with a flat‚ roughly triangular metal surface that‚ when heated‚ is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are stretched and the fabric maintains its new shape when cool. description: The electric iron must have a design and an electric iron basically consist of basically a heating coil and thermostat

Many of the houses which were built in the past several decades have attached garages (depending on what part of the country we are talking about) and therefore the garage is a complex part of the structure of the house in addition to being part of the kitchen or living room‚ usually through a standard doorway. Because the garage is nevertheless a part of the house; it is important to have the door insulated against the wind‚ rain‚ snow and other elements in order to keep utility bills under control

Abstract- A new heating method for hyperthermia using microwave and ultrasound simultaneously is proposed‚ and temperature distributions are obtained by computer simulations. The results have shown that the simultaneous use of microwave and ultrasound can heat wider and deeper region than the sole use‚ and can reduce the input power of microwave and ultrasound. This implies that we can reduce the hazards that high power microwave and ultrasound may bring about. SUMMARY: In hyperthermia‚ tumors are

Tashia & Tobi Lab Report experiemt 5 INTRODUCTION In this experiment we were wanting to find the specific heat of an unknown metal and determining what metal it was by using the formula q=c X m X change of temperature. We did two trials to compare the two and see what we come up with. EXPERIMENTAL First we chose an unknown metal‚ in which our unknown was unknown metal 2‚ the metal was gray and irregular shaped. We setup the calorimeter and got a mass of it just being empty then we got

Chemistry By Jarrod Ahern Abstract The aim of the investigation was to determine whether primary alcohols use less energy than secondary alcohols for fuel. The hypothesis is if primary alcohols are heated and results are taken‚ they produce a lesser heat of reaction then secondary alcohols. The method used was to find the average bond energies of three relating primary and secondary alcohols and compare it with the average theoretical values. Hence the primary alcohols produce less energy most of the

Many people think of flow path as the path the fire‚ smoke‚ and heat travel to either a failed window or a vent hole cut intentionally through the roof. While this is true there are many different things that can either help control the path or hinder it. It is essential for all firefighters and chief officers to understand how operations within the flow paths can place firefighters at risk due to the increased flow of fire‚ heat and smoke toward their location. As we have learned throughout this

beginning of a new day. Promising early heat and later in the afternoon heavy rain‚ this phrase shows how heat changes into rain. This explains how things change‚ nothing stays the same‚ it also explains how one thing leads to another. The early heat leads to evaporation of water‚ which condenses to form rain. The warm blue morning‚ will eventually change to heat and later to heavy rain. The poet uses the word promises before early heating‚ its like you cant avoid the heat‚ it will eventually come.

2.2 Peltier Thermoelectric cooler (TEC) Peltier thermoelectric heat pump is a popular thermoelectric energy conversion module that applies the Peltier effect‚ transferring heat energy from one side of the device to the other side. Peltier effect occurs when two different semiconductor materials (n-type and p-type) are joined together with electric current passing through its junction. Therefore‚ the junction could either be cooled or heated [28]. The Peltier TEC device can behave like a temperature
