Maricela Sandoval Period 2 10/27/12 Title of Lab: The Melting Temperature of a Pure Substance Purpose: The goal of this experiment was to find the melting point of Paradichlorobenzene and to observe the freezing/melting of a substance. The purpose was to also observe an endothermic and exothermic process. Introduction: The uses of Paradichlorobenzene are mainly as a fumigant for the control of moths‚ molds‚ and mildews‚ and as a space deodorant for toilets and refuse containers. It is also

.............. Automatic Temperature Control Fan Abstract: The automatic temperature control system is a very essential feature of a factory or an industry. In most of the case the temperature plays a vital role in the process of manufacturing or the process carried in that factory or industry. The most common and simplest way of controlling temperature is by using a fan which is automatically connected to a network such as it is switched on when the temperature of the

1. ABSTRACT Fahrenheit scale digital thermometer is a temperature indicator which displays temperature in Fahrenheit scale. It consists of two sections. One is that which senses the temperature. This is a temperature sensor LM 35. The other section converts the temperature value into a suitable number in Celsius scale which is done by the ADC0804. The temperature sensed in Celsius scale is converted into the Fahrenheit scale temperature just by using the Celsius to Fahrenheit conversion formulae

hydrogen tartrate (KHT) at various temperatures from 10°C to 50 °C‚ and determine the corresponding Ksp at these temperatures. 2. To obtain the changes in enthalpy and entropy of the dissolution of KHT from the dependence of Ksp on temperature. 2. Results and discussion 2.1 Collection of data A portion of KHT (1 to 1.5 g) was added into about 100 mL of deionised water to prepare a saturated KHT solution. Several such solutions were prepared at various temperatures between 10°C and 50 °C‚ and filtrated

Scientists have been studying species such as endotherms for years. Recently‚ scientists came about an observation. How do bees or any endothermic animal‚ generate the heat required to warm itself? Although Bees

determines the arrangement of the particles in a sample of matter. PLASMA - Electrically charged gas because of extreme temperatures‚ the particles move so quickly that their collisions release electrons from the atoms. - Mixture of electrons and positively charged ions with high kinetic energy is described as the plasma phrase. - Because of its extreme temperature‚ plasma is not common on earth. - The sun and stars are mad of elements in the plasma state‚ and plasmas can also be found

read “LO” when the control is in the automatic melt mode. If the temperature of the shortening is below 185º the control will enter the melt mode. When the temperature of the shortening reaches 185º hte control will go into the stand-by mode or to the first setpoint of the current cycle. Stand-by Mode - The display will read “COOL” when the control is in the stand-by mode. After filtering or programming‚ the shortening temperature is reset to 250º which extends shortening life and is also an energy

Molar mass Triple Point The temperature and pressure at which solid‚ liquid‚ and gaseous water coexist in equilibrium is called the triple point of water. This point is used to define the units of temperature (the kelvin‚ the SI unit of thermodynamic temperature and‚ indirectly‚ the degree Celsius and even the degree Fahrenheit). As a consequence‚ water’s triple point temperature is a prescribed value rather than a measured quantity. The triple point is at a temperature of 273.16 K (0.01 °C) by convention
