Once the can was hot enough it was quickly placed in a bowl of ice cold water and the can crushed itself. This occurred due to the pressure on the outside of the can being much greater than that of the inside. When the water inside the can evaporated the inside was left with the steam occupying the volume inside of it. Once the can was submerged all of the steam dissipated leaving the inside empty allowing the pressure on the outside to crush it in. The marshmallow and balloon lab were similar to these two demonstrations.
Haz Mat- Any substance or material could adversely affect the safety of the public, handlers or carriers during transportation. 1001- Acetylene; Extremely flammable gas and is unstable. as a precaution isolate the spill for at least a 100meters in all directions, and evacuate in a large spill or fire. First aide move victim to fresh air, give artificial respiration, administer o2, remove contaminated clothing. If contact was liquefied gas thaw the frozen parts with lukewarm water.
Tipping up the balloon causes the baking soda to mix with the vinegar and the resulting reaction gas pumps up the balloon. Balloons expand to different extents depending on how much carbon dioxide gas is produced and this depends on the quantity of baking soda and vinegar used. Place 1 teaspoon baking soda (4g sodium bicarbonate) in the balloon. Add 4 tablespoons of vinegar ( 60 ml of 5% acetic acid) into a 1 liter water bottle. Stretch the mouth of the balloon over the mouth of the bottle then turn the balloon completely upright so that the baking soda inside the balloon pours into the vinegar.
Water from Ocean evaporates and rises into the atmosphere. When the temperature and humidity reaches a certain level, combined with moisture in the air, it creates condensation which is the process that changes vapor into water again. Although rain water has been distilled as it evaporates, it is not distilled water because on the way down, it is not pure as it gets mixed up and dissolves all the dust and CO2 and becomes carbonic acid which is acid rain. 2) Port and sherry are called “fortified wines” because alcohol is added to a fermented wine to prevent it from turning to vinegar when exposed to air. Beginning with squeezed grape-juice which contains sugar, water and yeast, design a procedure for making a fortified wine.
How Much CO2 is in a Bottle of Soda? __Dr. David G. Haase, The Science House (2005-2006) I was wondering that the other day and remembered that one good way to get the carbon dioxide out of a soda is to shake it. My son demonstrated how to do this. This led to an experiment which you can try for yourself and investigate the amount of carbon dioxide dissolved in different beverages and how much can be released at different temperatures.
Supposedly we are going to have a huge blackout that wipes out all earth, and we would live in complete darkness; this would be caused by the sun, and it’s light. The polar shift theory is when people believe that the world will switch around and the north and south poles will switch. This would cause melting of the icecaps and create a huge tsunami. Unexpected super volcanoes are supposed to go off around the world and wipe out countries. None of these ideas are going to happen because these are outrageous possibilities that aren’t even close to happen or threaten
Engineers wanted to delay Challenger’s take-off; because warmer temperatures produce better launch probability. However, these concerns were ignored. The O-ring was frozen and could not allow joint flexure, which allows prevents leaks. The Columbia Space Shuttle accident is an example of both. The shedding of foam “normalized of deviance” violates human spaceflight safely.
Do this before it cools or water will travel backwards into your tube and contaminate your solid product. I 1 Collecting a liquid product: If you loosely wrap a damp paper towel around the upper-outer section of the boiling tube away from the flame, you might be able to condense a gaseous produCt into its liquid ·state. In addition to this you should cut a large piece of qualitative filter paper in half and then fold it and theri curl it inside the boiling tube near the rubber stopper. If a liquid forms, the finer paper will help absorb it and prevent it from falling back onto the solid being heated. Make sure the rubber stopper is securely in place since gas can easily leak out.
The bladder stores urine until releasing it through urination .Hot exhaust gases exit your engine and head through your exhaust to the catalytic converter. Inside this expanded tube is a massive network or honeycomb of ceramics. This ceramic checkpoint has been coated with compounds that react with the exhaust to eliminate certain harmful emissions. Even though the exhaust is flying through the tube at high velocity, the molecules that coat the ceramics are able to react in milliseconds, hanging on to the bad stuff until it's converted to something harmless (or less harmful) like Nitrogen, Carbon Dioxide or water
Gas or its inability to escape is what causes volcanos to become violent. The longer gas is trapped, the more pressure builds up. The cause of gas building up is the result of the viscosity of the magma the gas is trapped in. Viscosity is the measure of the flow or how easily a liquid flows. If a liquid is viscous it is thick and will flow slowly like honey whereas a liquid that is nonviscous will flow like water.
