materials given to us were hydrates by heating them and then dissolving them in water. Our results showed that all of our substances were hydrates besides the sucrose‚ sucrose if the only one which did not both bring condensation when heated and dissolve in water‚ which agreed with our hypothesis because we also thought that sucrose was going to be the only one that wasn’t a hydrate. The only error that we may have encountered in this lab was that when heating‚ the flame was not always the same temperature

carbon TRC tensile strength is shown in Figure 10. The mean results of strength‚ strain and elastic modulus (at 7 days of age + heating and cooling process) are given in Table 4. The values‚ as well as the standard deviations‚ refer to three TRC test specimens. As well as in the uncoated carbon TRC‚ a strain-hardening behavior is clearly observed in the stress-strain curves up to 400°C. Although not impregnated by matrix‚ the coated carbon TRC presented higher tensile strength than the uncoated TRC

The results were that the increase in insulation thickness increased energy saving‚ especially Beijing because of the heating energy use in the region (Pan‚ Dongmei‚ Chan‚ Deng‚ and Lin‚ 2012). For the Guangzhou and Shanghai regions‚ the thickness of insulation did not affect the sum of the heating and cooling

Water-Saving Ideas for Schools Free Repair leaky faucets and toilets throughout the school building. Encourage maintenance staff to avoid using hoses or pressure washers to clean sidewalks and other paved areas. Never allow water to run unnecessarily‚ and avoid using the toilet as a trash can. Avoid overuse of the air conditioning – the harder it works‚ the more water (and energy!) is used to cool the building. Encourage your school’s cafeteria staff to avoid

production of oil have been very close to the halfway point of its production rate. This graph above is known as ‘Hubbert Curves’ named after its inventor which is “Dr M King Hubbert” a world renowned geologist. The Hubbert peak theory says that‚ in regard to any given geographical area‚ from an individual oil-producing region‚ the rate of petroleum production tends to follow a bell-shaped curve. In addition to the threat to the world’s economy‚ increasing oil consumption challenges the environment and the
