the system was measured. The rate of heat output and the coefficient of performance are to be determined. A sketch of the vapor-compression cycle on a pressure-enthalpy diagram is also to be presented. In order to perform this analysis the temperatures at the inlet and outlet of the condenser and evaporator were measured for both the refrigerant and the water. The flow rate of the refrigerant through the system was measured and assumed to be constant throughout. The flow rate of the water was

Warm Temperature Measurements * Fill a 100 a 100mL beaker with 50mL of hot water. Get the water as hot as possible. * Use thermometer to measure the temperature of the water in the beaker using Celsius unit. Record measurement in Data Below. * Place the beaker of the water on the wire gauze burner stand. * Remove the cap from the burner fuel and set aside. Light the fuel and slip it under the burner stand. * Bring the water to full boil and record its temperature. Record

tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons The Tundra Biome is one of the most unique Biomes in the world. Covering one tenth of the earth’s land area it is a substantial Biome. Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi‚ meaning treeless plain. It is noted for its frost-molded landscapes‚ extremely low temperatures‚ little precipitation‚ poor nutrients‚ and short growing seasons. Major problems With

lowering (depression) (Brown‚ 542). For a substance to freeze‚ the kinetic energy of the particles must be low enough for the attractions to arrange the molecules in one position in a crystal structure. The freezing point of a solution is the temperature at 1 atm of pressure when both the solid and liquid phases are in equilibrium (Brown‚ 545). Solute particles cause the

Does the temperature outside affect how fast molecules move inside objects? Charles Law helps us understand how molecules move in different temperatures. It states that increasing the temperature of a constant pressure volume of gas causes individual gas molecules to move faster (Andrew Staroscik Staroscik 9/19/16)‚ and the volume is proportional to the absolute temperature of a gas at (Todd Helmenstine 10/16/16). Therefore‚ as the temperature increases‚ so does the speed of the molecules‚ and when

have very little rainfall as less than 50 cm a year with extreme temperatures and very scare vegetation. The fact that deserts are so dry the temperatures can change drastically‚ during the day temperatures can be as hot as 32 degrees Celsius‚ but at night temperatures can drop as low as -4 degrees Celsius because when the sun goes down there is no moisture in the air to trap the heat so it escapes into space creating cool temperatures. The organisms that can be found in this ecosystem are the

solid that looked like tiny crystals at room temperature. After putting it in the flame‚ the CoCl2 turned the flame purple and there were many sparkles. Na2SO4 The Na2SO4 was a small white solid particle at room temperature before the flame. Putting it into the flame caused the flame to instantly turn orange-yellowish. CaCl2 The compound CaCl2 was a white‚ hard‚ and chunky substance at room temperature prior to burning it. Holding it in the flame
