temperature change during the experiment. It was noticeable that the most efficient alcohol burner was Octan-1-ol as its average was 16.4KJ whilst most other burners were less than 10KJ. Introduction & Aims: Each alcohol that was used had different amounts of carbon and hydrogen atoms‚ as the amount of atoms goes up the amount of energy the alcohol releases goes up also‚ for example Octan-1-ol (C8H17OH) was the most efficient with the highest calorific value of 16.4KJ where as Ethanol (CH3OH) has a

one sip of methanol can cause permanent blindness. Two other kinds of acyclic acid are propan-2-ol and butan-1-ol. Just like ethanol‚ these two types of alcohols can be produced by the fermentation process. Propan-2-ol is a colorless‚ flammable chemical compound with a strong odor. It is the simplest kind of secondary alcohol which occurs when an alcohol carbons is attached to two other carbons. Butan-1-ol is a primary alcohol with a four carbon structure.

Propane-1-ol and Propane-2-ol would be the most appropriate to take on a camping trip to a national park where wood cannot be used to burn. Factors that need to be considered are: • Heat of combustion (flash point) • Heat of vaporisation (boiling point) • How long the fuel will last • Does the fuel heat up the water relatively quickly • Does the fuel combust completely Hypothesis: If the tests are all successful‚ Pentane should produce a larger flame than the Propan-1-ol or Propan-2-ol as it is

The sinking of this liner involves a sequence of events that led to its sinking‚ main participants and groups that were involved and affected by the sinking‚ and it created a great significance and importance after it was over. The sinking of the Lusitania occurred because of a series of events that led to its plummeting.

22 November 2013 Further Issues in Using OLS with Time Series Data • Last time‚ we discussed the assumptions necessary for OLS parameter estimates to be consistent in a time series context. • We also compared these assumptions with the assumptions necessary for OLS to be unbiased. • In general‚ the conditions are more restrictive for OLS to be unbiased than for OLS to be consistent‚ so in a time series context‚ it is fairly frequent to have OLS be biased but still consistent.
