The experiment had four different temperature 12 ̊, 51 ̊, 75 ̊, 111 ̊. In the experiment it was about how temperature effects the air pressure of a basketball. The one thing that would change the experiment is recording the bounce because participants had to get the bounce and the measurement. The highest bounce was the hot ball that was 111 ̊it bounce high. The lowest bounce was the frozen ball that was 12 ̊ because it barely bounced. Introduction Many athletes use basketballs, soccer balls

The studies discussed here that measured the constituents of latent fingerprints usually used gas chromatography- mass spectrometry (GC-MS) to identify the specific chemical compounds present in these prints and these results demonstrate the potential of GC-MS to monitor the ageing of fingerprints. Previous research in the above sections has shown that the composition of fingerprint residues is too variable to allow any prediction about the age of fingerprints within reasonable boundaries [Archer

The occurrence of large natural clathrate hydrate deposits on the oceanic sea floors and the possibility that these gas hydrates could be mined as an energy source of hydrocarbon gas or used to sequester CO2 gas are still attracting considerable interest. Gas hydrates form clathrate structures consisting of hydrocarbon molecules within "cages" of water molecules. There are two clathrates of practical interest, the sI and sII structures. The sII structure can accommodate propane molecules, which

experiment, set up the gas collecting apparatus. To start Part A, add approximately 15mL of distilled water to the test tube and record the temperature. Use about half of an Alka-Seltzer® tablet and record the mass. Close the test tube with the stopper with the tubing and tilt the test tube so the water and tablet react. When the reaction is finished, record the volume of CO2 recovered by lining the meniscus of the graduated cylinder up with the water level. In order to use the Ideal Gas Law equation, the

volume, does the pressure go up proportionally? Hypothesis If the pressure of a gas is at a constant volume then pressure will be proportional because as temperature rises, pressure also goes up. Materials Gay-Lussac’s Simulation Applet Procedure 1. The “Gas Properties” simulation was opened. 2. Under “Constant Parameter” the “Volume” button was clicked on. This ensured that the volume remained the same. 3. Under “Gas in pump” the radio button “Light species” was clicked on. 4. The “Measurement

average percent uncertainty of the time taken for 10.0 ±0.5 cm3 of oxygen gas to be evolved across all trials at each temperature was found by finding the percent uncertainty of the time taken for 10.0 ±0.5 cm3 of oxygen gas to be evolved for each trial then dividing it by 5 as there were 5 trials for each temperature. Example calculation showing the average percent uncertainty of the time taken for 10.0 ±0.5 cm3 of oxygen gas to be evolved across all trials at 297.0 ±0.1 K 0.0180.80 100%+ +0

Petroleum engineers deal only with sedimentary basin rocks in oil and gas drilling, and these sedimentary rocks are types of rock that are formed by the deposition of material at the Earth’s surface and within bodies of water. Permeability in these rock is a measure of the ease with which fluid flows through a porous rock

The soil lacks in nutrients. Therefore, greenhouses would have to be built and constructed in a way that the plants can adapt to the environment in almost a similar way to Earth. This would allow the plants to grow on Mars and over some time, create food for life on Mars. To have this greenhouse on Mars it would help grow plants for food, recycling and for replenishing the air. The main disadvantage to easily growing plants on Mars is the low atmospheric pressure that would make the plants act as

Do green house gas proportions vary with wind direction, and does it have an effect on temperature? This would be an interesting question because with the statistics related to this, we could then extrapolate on where the wind is coming from and the composition of green
