Have my phone ready to time how long it takes for the tablet of alka-seltzer to dissolve in the water. 3. Then‚ getting another cup‚ we have room temperature water. Then‚ we drop another alka-seltzer tablet into the water and time how long it takes to dissolve. 4. Repeating steps one and two with more water than

* MACRO ANALYSIS 1. If we look the map of Peshawar we came to know that railway station‚ airport and other five hotels are within 30 minutes drive from the site‚ so the site is feasible on macro level. 2. There are two types of architectural styles in Peshawar. The architecture towards the main city is very detailed and classical while towards the new localities we observe modern structures of concrete. Since our site is located in the new locality of modern structures so the architectural

Place the crucible on top of the tripod and under the calorimeter and light the ethanol. 10. Put the polystyrene cover over the calorimeter and stir the water gently. 11. When all ethanol has burned out record the highest temperature reading on the thermometer. 12. Record the temperature difference. 13. Do not change the

Position a thermometer bulb near the middle of the volume of water and record the result as initial temperature. Adjust the calorimeter with a clamp on a balance and leave enough space below the calorimeter for the burner. Add some sort of draught shield or any cardboard‚ books to avoid energy loss. This is important as continuous loss of heat can have significant

The purpose of this lab is to understand how temperature influences the texture‚ and firmness of fondant‚ and fudge. Materials and Methods: The ingredients that were used for the fondant recipe were 200 grams of sucrose or better known as table sugar‚ and 118 mL of water. The 118 mL of water and 200

about the lowest core temperature a human can have before perishing. The character wants to save time by going up the steep hill instead of following the road that has many switch backs this is when everything starts to go wrong. The character goes for about an hour with no sign of the road‚ while assessing the map he hears a metallic pop and a piece of his binding has popped out. The character is trying to find the piece of his binding and while he does this his body temperature begins to lower after

The Enthalpy Change of the Decomposition of Calcium Carbonate _INTRODUCTION_ RESEARCH QUESTION: What is the enthalpy change of the decomposition of calcium carbonate? BACKGROUND: Enthalpy in chemistry can be thought of as the energy contained within the bonds‚ or the internal energy‚ but it is not heat and you can only measure changes in it. When bond bonds break in the reactants energy is given off‚ when bonds form‚ energy is absorbed. If the energy absorbed is less than the energy released

and remains constant for a reversible system‚ but never decreases. An air-conditioner functioned by using a working fluid to transfer heat from the colder indoor air to the hotter outside air. So the indoor air will be cooled down to a favorable temperature for indoor activities. Second law of thermodynamics defines as the entropy of an isolated system never decreases due to isolated systems spontaneously evolve towards thermodynamics equilibrium. Air conditioners apply it during its function. Air
