Thermodynamics-Enthalpy of Reaction and Hess’s Law Purpose To demonstrate the principle of Hess’s Law and to find the heat capacity of the coffee cup calorimeter using three different reactions. Data Tave = (46.4-45.2)/2 = 45.8 qwater = -(100g)(4.184)(46.56-45.8) = -318 J Ccal = 318J/(46.56-21.2) = -12.53J/g*C Tinitial = (27.1+23.8)/2 = 25.45 qrxn = -(100g)(4.18)(38.43-24.45)+(-12.53x12.98) =-5400J/.1mol(1J/1000kJ) = -54.0 kJ/mol Tinitial = (26.0-24.5)/2 qrxn =-(100g)(4

would open causing perspiration‚ the heart rate would rise‚ and the surface blood vessels would expand bringing more blood to the surface of the skin where heat could dissipate. Likewise‚ in the home system‚ the air conditioner would kick on and circulate cold air throughout the home. All of these things are the causes for a response. In the body‚ heat is dissipated and body temperature begins to return to normal‚ and in the home‚ the air conditioner would return the ambient temperature back to the setting

Investigate the effect of temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction

roof is one place where you are losing a substantial amount of energy in your home. This is because multiple pieces are used to construct a roof‚ so it is not a solid piece. There will be tiny gaps that allow the air to escape your home‚ and allow the heat from the sun to get into your home. Thankfully‚ there are two ways that you

studied the impact of heat input on tensile strength‚ toughness‚ micro hardness‚ micro structure and corrosion behavior of duplex stainless steel joints. Four parameters were varied by keeping speed as constant. The heating pressure of 30‚ 40‚ 50 MPa‚ heating time of 3‚ 4‚ 5 sec‚ upset pressure of 60‚ 70‚ 80 MPa‚ upset time of 2‚ 3‚ 4 sec were used to weld the joints. L9 orthogonal design concept was used. Results revealed that no intermetallic phases were formed. By increasing the heat input the tensile

The Metaphor of the Melting Pot Peggy Ruth Geren The melting pot has been used metaphorically to describe the dynamics of American social life. In addition to its descriptive uses‚ it has also been used to describe what should or should not take place in American social life. How did the term originate? How was it used originally? How is it used in contemporary society? What are some problems with the idea of the melting pot? How is public education connected to the idea of the melting pot?

temperature rise of the heater is converted into a voltage by means of the Seebeck effect which is also temperature-dependent‚ the mean output voltage will therefore differ when dc and low-frequency ac inputs are applied‚ thus leading to an ac–dc transfer difference. 3.2 MULTIFUNCTION CALIBRATOR The Fluke Model 5700A/5720A Series II calibrators are precise instruments that calibrate a wide variety of electrical measuring instruments. These calibrators maintain high accuracy over a wide ambient temperature

The Little Heat Engine: Heat Transfer in Solids‚ Liquids and Gases The question now is wherein the mistake consists and how it can be removed. Max Planck‚ Philosophy of Physics‚ 1936. While it is true that the field of thermodynamics can be complex‚1-8 the basic ideas behind the study of heat (or energy) transfer remain simple. Let us begin this study with an ideal solid‚ S1‚ in an empty universe. S1 contains atoms arranged in a
