Pure water boils at 212˚ Fahrenheit (100˚ Celsius) at sea level, but water can also boil at temperatures as low as -90˚ Fahrenheit (theoretically). The reason for this phenomenon is pressure. “There is a direct correlation between pressure and temperature when it is dealing with the boiling point of water,” says Jacob Young, a mechanical designer at Blauch Brothers, Inc (Young, J.C. 2017). The pressure on Earth at sea level is 14.696 PSIA (Pounds per Square Inch Absolute). This pressure is…

1. Introduction Every human being tends to try connecting the events by causes and effects. We believe that everything that happens need to have a causal explanation. This is simply how the human mind works. On account of this, causal relationships can also be observed in every branch of science. For instance, medical specialists search causes of the diseases. Similarly, physicists observe causes of the effects on the nature. This is a reason why even the simplest laws of physics have causal…

Anxiety, fear, phobias and stress therapy As you are here for a reason, most probably you know how difficult it may be to live with anxiety, phobias, panic attacks and stress. You are aware of your feelings and your self sabotaging emotional pattern. You know your fears, and you might know how you developed them, or the motivations behind each of your fears. Yet, you know how difficult and frustrating it can be when your life seems to be controlled by overwhelming feelings that you are trying…

Chemistry plays a vital role in everyday life even though it may not seem like it. One of these things include firearms, which exhibits chemistry throughout the whole entire process. They show chemical and physical properties ranging from the gunpowder to the actual process of firing a bullet. Gunpowder is what makes the whole reaction occur. Without the use of chemistry throughout a firearm, would make it useless and it wouldn't work. These uses of chemistry occurs so fast that you may not…

1.I believe not all the humanistic behaviors proved the humans free will but simply shows that we as human exercise our free will. The choices we make in daily bases is a good example of our personality, and all the choices we make has an effect and follow some consequences. The term of free will makes us differ from other creatures, presence of this matter create motivation to move forward in life. For example when we mix to different chemical together and the reaction occurs makes those…

SECTION 2: NON-PHARMACOLOGIC APPROACHES TO CHRONIC PERSISTENT PAIN Abstract: Non-pharmacological therapies have become a vital part of treating CPP. The combination of both non-pharmacological and pharmacological therapies is termed multi modal. In general non-pharmacological measures are used to augment and complement pharmacological treatments. They can be classified as non-invasive or invasive methods. They include physical, cognitive, behavioral or complementary therapies. Clinicians should…

In part C, the enthalpy of formation of magnesium oxide was found by adding together three reactions, as shown in the table below. Experiments were performed to obtain the ΔHrxn value of the first two reactions in the table, which were reactions 4 and 5 respectively in the experimental section, while the ΔHrxn for the third reaction in the table was provided. Using the ΔT obtained experimentally, heat energy (q) was determined using the equation q = mCΔT + CΔT where q was the heat, m was the…

In every experiment there are constraints and requirements. Specifically in our Solar Oven Project we had budget, material, and performance constraints. The inside chamber, where the biscuit is cooked, must have a volume of 1000 cm3. In addition to that, the length of the window and the depth of the inside chamber must be at least 5 cm. The window must also be a square. The inside cooking chamber must be able to easily insert and remove the biscuit and hold the biscuit in place so when the oven…

history, and human comprehension. When you take a step backward and genuinely contemplate archeological discoveries, you will uncover no evidence for evolving creatures but only many missing links. If you investigate science, especially the laws of thermodynamics, you will gather that evolution disregards all the guidelines of how the universe truly functions. When using our multifaceted brains and observing nature, we ought to acknowledge that these curiosities could not have materialized by…

INTRODUCTION Chemically and thermodynamically foam is an unstable, dispersed system of entrapment of gaseous molecules in solid or liquid matter. Instability of foam is caused generally due to coalescence, liquid drainage and disproportion of bubbles. Foam being aqueous system can be produced using surfactants available commercially. The types of surfactants used in preparation of aqueous foam influence the foam properties (Eisner et al., 2007; Bhakta and Ruckenstein, 1995). Successful foam…
