Insulating buildings more effectively‚ changing the industry process and driving aerodynamic cars would reduce the demand for energy use. Some household appliances conserve energy. A desktop computer generates less heat and is made of recyclable materials. A dishwasher has a booster heater that raises

plastic cup in this experiment is that the plastic material is too thin which will cause the outside surface of the plastic cup to be hot due to conduction. Furthermore‚ plastic is not a good insulator as compared to polystyrene cup and this will cause heat loss which will affect the reading of the experiment ii)NaOH is a strong alkaline solution that can cause severe chemical burns if it is in contact with skin f)i) Since the paper coffee cup gets so hot‚ many coffee shops provide a thin cardboard

A certain fluid at 10 bar is contained in a cylinder behind a piston‚ the initial volume being 0.05 m3. Calculate the work done by the fluid when it expands reversibly: a. at constant pressure to a final volume of 0.2 m3; b. according to a linear law to a final volume of 0.2 m3 and a final pressure of 2 bar; c. according to

independence from the environment. Regulating body temperature is one instance where homeostasis occurs (Thermoregulation). Some methods are conduction‚ where the body absorbs/removes heat via contact surfaces; convection‚ which is the upward flow of warm air or the downward flow of cold air past the body; radiation‚ where heat is transferred/received via infrared waves on non-contact surfaces; evaporation where water on the body is evaporated giving a cooling effect. To maintain a constant body temperature

HEAT TRANSFER OF BALL BEARING Muhammad Sabry Anwar Bin Sazali 2011297756 BACKGROUND A steel ball bearing at 1200K is need to be quenched for 30 seconds in water that is maintained at a room temperature of 300K after heating them to a high temperature of 1000K. However‚ it takes time to take the ball from the furnace to the quenching bath and its temperature falls. If the temperature of the furnace is 1200K and it takes 10 seconds to take the ball to the quenching bath‚ is less time needed

CHAPTER 1 Introduction Some farmers who don’t have irrigation system‚ plant rice during rainy season so‚ they have the difficulty of drying their grains after harvest. Aside from these‚ drying the grains under sunlight takes longer time‚ more effort in handling to the drying site‚ scraping or ricking‚ guarding from animals‚ collecting after drying‚ and another is that the possibility of the grains to be mixed with stones‚ leaves of tree‚ and dust in road drying and field drying. There are many
