of the implementation of gas laws. The physics are based on the simple principle that warm air rises in cooler air. Hot air has less mass per unit of volume. The relevant gas law in use is Charless Law‚ which is V1/T1=V2/T2. The law states that raising the temperature (T1) will also increase the volume (V2)‚ in order to keep the equation true. Generally‚ air is heated through the use of propane burners. When ignited‚ the volume of the gas increases but the balloon cannot expand much‚ so air will

Tourism is a Myth.’ To what extent do you agree with this statement? (15 Marks) Sustainable Tourism is essentially an industry committed to making a low impact on the natural environment and local culture‚ while helping to generate income and employment for local people. As Global economists forecast continuing international tourism growth‚ this continuous growth will place great stress on remaining biologically diverse habitats and indigenous cultures‚ which are often used to support mass tourism

Guardians of the Galaxy Volume 2 is a continuation of Guardians of the Galaxy. After a group of criminals combines forces to fight a villain with his mind set on destroying the galaxy in the first movie they have to do it all over again in the sequel. The sequel is very similar at the core but there are a few differences. Now‚ in Volume 2‚ Petter Quill learns the identity of his father the Demigod and planet Ego. Once Ego’s diabolical scheme to take over the galaxy is revealed the unlikely group

1. How do you calibrate an Oscilloscope? In order to calibrate the Oscilloscope‚ we connected the BNC alligator into the channel we wanted to calibrate (Channel 1). We clipped the red probe to the calibration knob‚ and we saw a 2 volt VPP signal. The desired output from the oscilloscope was a 1000 Hz calibration frequency. The 1000 Hz frequency is the standard frequency for most of the oscilloscopes. After we clipped the red probe‚ we saw a square wave signal. The first thing we calibrated was the

Molar Volume of a Gas – 10/27/08 Alic Albright‚ Josh Coleman‚ Dan Boden‚ Zach Babin Purpose: The pupose of this lab was to make an experimental determination of a molar volume through reaction of the substance shown: Mg(s) + 2HCl(aq) > MgCl(aq) + H(g) Introduction: In this lab‚ a magnesium ribbon and HCl are combined in a gas measuring tube. When they are combined they form magnesium chloride and Hydrogen gas. The molar ratio between Mg reacted and

Mains gas is most likely to be piped natural gas. The most serious risk to human health is via a leak‚ however small‚ in the piping system that transports the gas inside the building. Natural gas is a mixture of hydrocarbons‚ including methane. It is colourless and odourless‚ which makes a leak difficult to notice. Exposure to high levels of natural gas quickly causes unconsciousness and even death. Exposure to low levels can cause dizziness‚ nausea or heart palpitations. It has this affect because

In many countries today insufficient respect is shown to older people‚ even from their own children‚ and this can be seen as more old folks home had been build nowadays. Thus‚ I will be writing about what I think the reasons may be and the problems that might cause in society. Firstly‚ the reason for this may be due to the old-fashioned thinking that they have‚ which makes it a problem for

Gas Exchange The process of gas exchange in the body is called respiration. This process has three basic steps that involve pulmonary ventilation‚ external respiration‚ and internal respiration. All three steps are functions that involve gas exchanges between the lungs and the atmosphere. For instance‚ pulmonary ventilation‚ or breathing involves the inhalation and exhalation of air between our lungs and the atmosphere. External respiration is the exchange of gases across the respiratory membrane
