Aim To find out difference in the heat of combustion for different types of alcohols. Hypothesis The higher the number of carbon atoms in an alcohol is‚ the higher the energy for the heat of combustion. Alcohol is a homologous series‚ a series of organic compounds with similar formula and chemical properties‚ and increase in molecular size and mass. When the equations for combustion of these alcohols are listed in the order of increasing number of carbon atoms‚ Methanol 1 CH3OH(l) + 3/2 O2(g)

fiber perform 2.3.1.a.1 MCVD (modified chemical vapour deposition) Process 2.3.1.a.1.1 is mainly used to create glass fibers where silica soot is deposited on the inner wall of the glass tube. This process is called virification. 2.3.1.a.2 OVD (outside vapour deposition) Process 2.3.1.a.3 is a process quite similar to the MCVD‚ it differs by depositing silica soot on the surface of the target rod. This process is commonly used in the creation of plastic optical fibres. 2.3.2 Drawing the fiber

ABSTRACT This study was conducted to determine the possibility of using yellow bell seeds crude extract as fuel.Mature yellow bell seeds were collected‚ cleaned‚ and ground using mortar and pestle. Water was added before the juice was extracted. To remove excess water‚ the juice extracted from the seeds was boiled and was allowed to cool. Testing on the use of the crude extract for lighting purposes then followed. Results show that it is possible to use the crude extract as substitute for kerosene

potential customers from the streets instead cries out ““weep! weep! weep! weep!”” (Blake 520). The irony presented here is through the play on words sweep and weep.

Further irony can be seen in the cheery tone of the child uses when speaking to comfort his friend who is upset after having his head of beautiful

the first line of the poem the first speaker is addressing the child as “A little black thing among the snow” to dehumanize the child (Blake 1). Blake not only shows the speaker’s voice as harsh but also uses imagery to display the amount of black soot that the child is covered in compared to the white snow in order to highlight the child’s physical conditions. Sold by their parents at a young age‚ chimney sweepers entered a life of torture and hardship. Then‚ to draw the reader’s attention to the
