(e) Dalton’s Law Challenge Question: Ordinary air contains about 78% nitrogen, 21% oxygen, and small amounts of several other gases. As a diver descends, the pressure of the air he is breathing increases by about one atm for every 10 m of depth. Oxygen may become toxic and cause convulsions if it is breathed at a pressure above 1.4 atmospheres. According to Dalton’s Law, at what depth should a SCUBA diver be concerned about oxygen toxicity if he is breathing ordinary air? Discussion Points: •…

Education and Care. Using the table below, explain in your own words the following aspects of basic home fire safety: Fire spread and speed Fire can spread very fast it can take few minutes to transfer from point to point Heat transfer The fire can transfer from place to place by heat transfer Radiation Is how he fire can transfer by rays Convection Fire can transfer through liquid or gas due to the circulation…

those predicted by Gillooly (2006) is that fully grown sauropods had mechanisms that regulated their body temperatures. A tracheal surface and air sac system that served as an internal cooling system, along with long necks and tails that facilitated heat dispersion could have been effective cooling methods that the sauropods…

Bernie Sanders said, “Every day we are paying more for energy than we should due to poor insulation, inefficient lights, appliances, and heating and cooling equipment - money we could save by investing in energy efficiency”. My family’s pre-home energy bill correlates to what Mr. Sanders was saying. They were paying more than they had to due to poorly conserving energy. My FPL bill prior to this project was $210.63, which was normal since it was the summer and the air conditioning unit was…

Wake up in the morning, pop my ankles. Sit down to eat breakfast, pop my back. Go to school and sit at a desk for an hour, pop my neck. You could say that “popping” has become a bad habit. Sometimes I will pop my knuckles consciously, while other times, the need comes absentmindedly. Every time I lay down for bed I pop my toes…weird I know, but popping has become a part of me. Why you might ask? Cracking and popping used to be something I did when I was bored or nervous. Now, it is just a way…

biologically sensitive enzymes and cells. Thus, allowing animals to survive in different environments including some extreme ones i.e. desert. Ectotherms such as lizards which have resultant control over metabolic processes, can thermoregulate through heat exchange processes based on behavioural or physiological adaptions (Huey & Slatkin, 1976). Other fascinating characteristic of some lizards is colour changing which normally…

analyze the data collected using Excel. In order to achieve this Newton’s Law of Heating and Cooling was compared to the data collected by a thermometer attached to the Lab Pro. Theory: Thermometer’s measure temperature through thermal equilibrium. Heat is transferred from an object to the thermometer at a rate proportional to the temperature difference between the two. Newton’s Law says Where T is the thermometers temperature, To is the objects temperature, and ΔT/Δt is the average rate…

blood. The Processing centre triggers for the effectors (these are the sweat glands and muscles) to adapt in order the make sure our body temperature stays at 37°C. If we need heat or need to get rid of it the processing centre will send nerve impulses to the skin which will then do one of the two things. To lose less heat then the hairs on your body will stand up, this traps more warmth for the body. When the body is…

Some scientist didn’t believe that the popping noise had anything to do with gas bubbles. To follow up on this hypothesis, some scientist used an MRI to prove the “gas bubble theory” wrong. First, scientist had studied 10 joints by using volunteers’ fingers into a tube. They did this so they could apply traction to the joint. They had specifically used the metacarpophalangeal joints because those were the most common joints that people crack. Then, they took images before and after cracking the…

How Temperature Affects A Glow Stick Glow sticks come in many shapes, sizes, and vibrant colors and are a quite popular object to take to places such as parties. There is one problem with all glow sticks that everyone has to face and that is having it last for an extensive amount of time. The scientific question being asked in this experiment is, how does temperature affect how long a glow stick stays lit? To solve this problem an experiment to see which temperature of the water a glow stick…
