Cooling Rate Of Coffee
1,679 wordsExperiments to Determine the Cooling Rate of Coffee, when Milk should be Added and what Container should be Used The aim of the first experiment was to find out and record the cooling rate of coffee under three different conditions and thus showing when milk should be added assuming you have a phone call. The three different conditions were chosen because these were the most likely situations encounter by someone who is making a cup of coffee. We used Tain instruments to accurately calculate the...

Scuba Diving Heat Loss
1,163 words... sk is needed because the human eye cannot focus without any air space in front of it. A mask provides the air space. Without the mask, you can see large objects, but they will be blurred and indistinct because your eyes cannot bring the rays of light into sharp focus. Only by wearing a mask can you see sharply (Ascher, 9). Light travels at a different speed in water than in air. When light enters the air in your mask from the water, the change in speed causes its angle of travel to shift sli...

Carbon Atoms Specific Heat
4,299 wordsI am going to investigate the difference in enthalpy of combustion for a number of alcohols, the enthalpy of combustion being the enthalpy change when one mole of any substance is completely burnt in oxygen under the stated conditions. I will be attempting to find how the number of carbon atoms the alcohol contains effects the enthalpy change that occurs during the combustion of the alcohol. Method I plan to measure the enthalpy change by burning the alcohol, using a spirit burner, I will then u...

Target Heart Rate Blood Vessels
2,314 wordsAsthma is a pulmonary disease with the following characteristics: 1) airway obstruction that is reversible in most patients either spontaneously or with treatment; 2) airway inflammation; and 3) increased airway responsiveness to a variety of stimuli (Enright, 1996, p. 375). There presently exist many varieties of asthma that differ in the severity, means of induction, and methods of treatment. One type is exercise-induced asthma. Exercise-induced asthma (EIA) is a temporary increase in airway r...

Naturally Occurring El Nino
3,100 wordsThe signature Species of the Southern Hemisphere (Antarctica) the mascot if you will is the penguin. There are not one and no fewer than seventeen species of penguins. Penguins are flightless birds in which several factors are contributing to the reduction of the penguin population. These contributing factors are both man-made and naturally occurring. ? The origin of the word? penguin? has been the subject of debate for a long period of time. Researchers and historians? theories range from refer...

Heat Loss Specific Heat
2,132 wordsPhysics Group 4 Project? ? ? ? ? ? ? ? ? ? ? After being set our initial topic of the bath tub, we chose as a group to investigate the heat lost from a bath tub. ? We initially experimented with ideas such as using different shapes, sizes and materials. ? Eventually, we decided that the easiest option was to investigate how the thickness of a bath tub effects the heat loss, as well as how conduction, convection (evaporation) and radiation effected the heat lost from a bath tub and how we could r...
