In fact, the wax itself is burning as a vapor or gas. Objectives 1. What happens to the candle when you light it? 2. Can you prove that the candle needs oxygen in order to burn?
Tammy Thanaporn Amornkasemwong 1st September 2011 Science Period 8 Introduction: How much energy can be released from fuels? Combustion is the process of burning fuel in order to produce heat. The intention of this experiment is to find whether different fuels produce different amount of energy. In the process of combustion in this experiment, cheeto, half a cashew nut, wax candle and ethanol are used as fuels combust with lighter, as heat and oxygen. When the fuels combust, oxygen and fuels react, and heat released.
Heat Of Combustion Of Candle Wax Purpose: The purpose of this experiment was to determine the amount of heat that was released when a gram of candle wax burns. Materials and Equipment: Empty pop can Candle attached to a piece of cardboard Celsius thermometer Ring stand Iron ring Stirring rod 250mL beaker 100mL graduated cylinder Ice Data and Observations: Mass of pop can and water: 149.88 grams Mass of empty pop can: -14.05 grams Mass of water in pop can: 135.83 grams Mass of a candle stuck to a piece of cardboard: 31.77 grams Mass of candle and cardboard after candle burned: -31.01 grams Mass of candle burned: 0.76 grams Final temperature of water in pop can: 35.0 (C Initial temperature of water in pop can: -9.5 (C Change in temperature: 25.5 (C Calculations: q = m ( c ( (T q(# of cal. or joules absorbed by the water) = m(mass of water in grams) ( c(1 cal./1g 1(C) ( (T(change in temp. (C) c = 1.00 cal/g (C or c = 4.18 J/g (C Conclusions and Questions: 10. (a.)
The beaker was then moved to a stir plate with a stir bar and held in place by a ring stand. A funnel attached to an aspirator hose was fixed above to serve as a fume hood. With the aspirator and stir plate both on, 4.79 mL of 6 M HNO3 was added slowly to the beaker until the copper dissolved and the solution turned a light blue color. The hood could now be removed and 10.02 mL of distilled water was added to the solution. While stirring, 6 M NaOH was added drop-wise until the solution became basic, turning red litmus paper blue.
Measure approximately 1 g of Copper(II) Sulfate Hydrate into the crucible and crucible and lid. 4. Heat the crucible gently. 5. Stirring carefully and observe the color of the hydrate until it changes to a consistent white color, then the Copper(II) Sulfate is dehydrated.
Can Smoke Be Manufactured? Keenan Todd Brandon Washington Kevin brown Christian Teate To most people smoke is what is given off or emitted when combustion is in progress, but is that the only way it can be produced? That is the basis and purpose of our science project. We are striving to discover if there is some sort of manufactured solution to producing smoke, what exactly smoke is, and also how could it benefit our lives. So it has already been proven that smoke can be emitted by burning items, or by use of friction with wood, and also many other natural ways.

Heated the mixture on the stove and stirred until the sugar has dissolved. Ater this the solution was removed from the saucepan and poured into a container and labelled that container 1% sugar solution. B) Rinsed the saucepan and then added 100 grams of sugar to the 250ml graduated cylinder and then added water up to
In fact, Elie is trying to adapt to his Jewish traditions. “We used to stay in the synagogte after all the faithful had left sitting in the gloom, where a few half-burned candles still gave a flickering light.”(pg7) In other words, Elie was doing a Jewish tradition. “There are thousands of gates leading into the orchard of mystical truth.”(pg3) Furthermore, he was going to acquire knowledge about some truth in his religion. “We would read together, ten times over, the same page of the Zohar.” (pg3) However, he would read it over and over again to learn it by heart. Elie is acquiring knowledge about his traditional Jewish values by studying the Cabbala and reciting his prayers.
Many resources that America has now were discovered/made useful during the industrial revolution. Long before Americas set foot on what is now present day America; Native Americans used crude oil for medicine and fuel. In the 1840’s Americans started to make kerosene out of these crude oils to light lamps. The man accredited with finding out how to make crude oil and
