Introduction Imagine if you fell asleep on your chemistry book one day during Mr. Sanders class and woke up in a completely different world. Within this strange world are horses that can talk, a lion that can not only talk but he is also friendly enough to allow you to ride on his back and wolframs. In the book, The Chemy Called Al by Wendy Isdell, Julie shares what it is like to experience all different kinds of adventures evolving around horses who can speak, friendly lions and wolframs. The…

selection’s apathy toward suffering with a god that is exclusively good. It is also hard to resolve the conflict between an involved god and the many elements of chance present in the process of natural selection. Even in a world without religion, Kelvin, a scientist, tries to rectify the ocean’s divergence from this religious ideal by molding the ocean into a new a type of god: one that is limited and flawed (Lem, “The Old…

I think Walter Fane is innocent because of his mother’s descriptions of him and the pleasantness he shows to Gwenda. Mothers usually know their children very well, and I would be surprised if Mrs. Fane really didn’t know her son that well. Additionally, there is only one instance in which he showed violence and a crazy temper. This was when his brother broke something he had worked so hard for. Walter was clearly very attached to Helen, and she broke his heart twice, but according to Mrs. Fane,…

Mangus?” “How do you like my new armor?” “Impressive, I must say.” “I believe the fight may be more even now, my friend.” “That it will be, Mangus.” They each carefully slipped wooden protectors over their blades since neither man wished to receive any serious injuries if they happened to get a little over zealous during their match. “Shall we begin?” Travin raised his blades and swung them toward Mangus’ head which he managed to block successfully. Travin moved much faster than he thought…

various arbitrary scales such as Fahrenheit, Celsius, and Kelvin. The Fahrenheit scale sets 32° as the freezing temperature for water and it assigns 212° the boiling point for water (What is Temperature, 2015) At the temperature of Absolute Zero there is no motion and no heat. Absolute Zero will occur when every atomic and molecular movement ceases and is at the lowest temperature possible. Absolute Zero on the scale is 0 degrees Kelvin, -237.15 degrees Celsius, or at -460 degrees…

for the earth. With the earth’s average temperature at 288 kelvin, the equation σT4 gives us a radiative energy flux of 390 Wm-2 (note that σ = the Boltzman constant = 5.670373×10−8 W m−2 K−4 and T= temperature). However, this 390 Wm-2 does not leave earth’s energy in balance since the income is 240 Wm-2. By simply applying the income energy value (240 Wm-2) to σT4, we can calculate earth’s average temperature which comes out to 255 kelvin or -18 Celsius. Hold on! Negative 18 Celsius…

Introduction: The enthalpy change of combustion can be calculated using the formula △H = MC△T, where △H is the enthalpy change in kJ mol-1, M is the mass in kilograms, C is the specific heat capacity in kilojoules, and △T is the temperature change in kelvins. In this experiment, I will be investigating the enthalpy change of combustion after heating five different alcohol fuels for five minutes, including methanol, ethanol, propanol, butanol and pentanol, by measuring the heat energy…

Law relates several variables of state of an ideal gas with the following equation: P V = n R T, where P is the pressure of the gas in atmospheres, V is the volume of the gas in liters, n is moles of the gas, and T is the temperature of the gas in Kelvin degrees. R is the ideal gas constant. The Ideal Gas Law is a combined summary of Boyle’s Law, Charles’s Law, and the Avogadro’s Law. This Law works best under low pressure, room temperature (298K) environments because these environments allow…

In this lab experiment, we will be using an unknown volatile liquid in order to understand the direct relationship between the molecular weight of a gas and its vapor density, which will help us determine the molecular weight of the unknown. The necessary tools that are essential in this experiment include: a balance, watch glass, two pieces of foil (2.5x2.5 inches & 3x3 inches), boiling chips, a ring stand, a thermometer, a bunsen burner, and an 800mL beaker. During this experiment, we have to…

1. What is meant by the luminosity of the Sun? a. The luminosity of the Sun is the total amount of energy that is emitted by the Sun every second. (Slater) 2. What is thermonuclear fusion? Why is this fusion fundamentally unlike the burning of a log in a fireplace? a. Thermonuclear fusion is the conversion of hydrogen nuclei into helium nuclei. b. The chemical reaction of burning a log on Earth would cause the outer electrons of the atoms involved to rearrange themselves. But, this change…
