Tirrill Burn Experiment

The very first experiment had the hypothesis that the temperature of a burner flame can be controlled by adjusting the ratio of gas to air in the mixture to be burned. During this experiment, my partner and I gathered our materials of the paper matches, straight pins, copper wire, laboratory burners, rubber tubing, tongs, and evaporating dish. Making sure we had our safety goggles on and the material we needed, we connected the Tirrill burner into the gas and lit the burner with the match, having the air vents closed and the gas on. When the burner was lit, we noticed that the flame had a luminous, smoky yellow appearance. We then used a pair of tongs to hold the evaporating dish towards the top of the flame for 10 to 20 seconds. We observed
During this experiment, we were able to grasp the understanding of the different ways a solid and liquid can be transferred from one bottle to another. First, we learned how to transfer a small amount of liquid and that was by using a dropper pipet. However, a larger amount of liquid required more work as we transferred the water from one container we used a stirring rod that held in place over the opening of the container to direct its flow nicely into the other container. We also learned how to hold the stopper between our fingers to avoid contamination. Next, we learned about how to transfer solids from one container to another. We had to decide if the solid was flowing freely or was a cake like mixture that clumped together. When we used the salt, we noticed that it flowed freely, so we used a spatula to transfer it into the watch glass. When transferring a small amount of solid, when using the spatula I tapped the back of my hand to allow small particles of the salt to go into the watch glass instead of pouring it all in. However, we noticed if the solid does not move freely, we had to loosen it by shaking the container or by breaking the particles down using our spatula. If the solid was freely moving we would transfer the bottle to the beaker by rotating the container so that it will freely run while it is being transferred. By doing this experiment my lab partner and I
During this experiment, my lab partner and I learned of the two different types of filtration we can use in the laboratory. Those two types of filtration were the gravity filtration and the vacuum-assist filtration. We used chalk at the solid that needed to be filtered in the water solution, noticing that it was the suspension in the experiment. First, I prepared the filter paper correctly folding it in half and then in quarters so that when I opened it formed a cone. Then, if put the paper cone in the filter funnel and placed it on the ring stand that was also used in experiment 1.2. My lab partner then made sure the filter paper was moist with water to hold it in its place. We made sure that the filter funnel touched the inside of the wall in the beaker to make sure that the liquid will drain faster. Next, I grounded a piece of chalk using a pestle and mortar and transferred the chalk into the beaker adding 75 milliliters of water and mixed it thoroughly to make a suspension. My lab partner then poured a small amount of the chalk mixture into the funnel with a glass rod as we waited for it to be filtered into the beaker. Once it was done, we noticed that the chalk was still in the funnel safely with the filtered paper and the water had filtered out into the beaker into a nice clear color blue. The next filtration
