Mineral oil is most commonly put to use in our daily lives as baby oil‚ which has a fragrance added to it. It is clear‚ odorless and colorless. It is formed as a by-product during the distillation of petroleum from crude oil‚ to produce gasoline and other petroleum-based products. It is produced in very large quantities and is inexpensively available in drug stores. Due to its easy availability and low value‚ it is put into use in a wide range of avenues. As a Laxative Doctors often recommend

to working with the lab equipment‚ specifically heating and measuring‚ and to be able to create some of the apparatus that future experiments will require. Heating methods used were an aluminum block‚ a sand bath‚ and a water bath. The aluminum block heated most quickly while the others were more stable. Regarding the measurement of water‚ the less volume of water that was being transferred‚ the less accurate the measurement turned out to be. Heating Methods: Aluminum block: Heat setting Temperature

Sick Building Syndrome | Heating and Air Conditioning Sick building syndrome (SBS) has is mainly recognized in commercial settings‚ such as office buildings where a large number of persons work. However‚ tightly constructed homes can also experience it. SBS is the result of tight construction and a reduction of fresh air entering the indoor environment. As the call for energy efficiency increased beginning in the 1970s‚ the quality of indoor air continued to fall. SBS is the unwanted result. Fortunately

captures the heat energy of sun and delivers it during winter and pumps out the heat in summer‚ using heat distribution methods. Some of the heat distribution methods are Convection‚ Conduction‚ and Radiation. However components of passive solar heating are‚ the aperture area of the house‚ absorber area of the house‚ thermal mass of the house‚ heat distribution‚ and solar control. When these components work together it contributes to an efficient green building. In passive solar technique‚ glazing
