Kari Kargus Expository Assignment June 29th‚ 2017 Baking Peanut butter cookies is fun at any age! In order to make scrumptious peanut butter cookies‚ you must follow these quick and easy steps. First‚ make sure you have all your ingredients. These include: peanut butter (1 cup)‚ sugar (1 cup) and an egg. Once you have all your contents‚ preheat your oven to 350 degrees F. Be sure to check when your oven is done heating. Next‚ mix your three ingredients in a large mixing

Ailine Veiga Question: what is the heat of fusion of ice? Hypothesis: To get the heat of fusion of ice we need to determine the Energy it takes to melt the ice and also the mass of the ice and determine the heat of fusion. To determine the mass of the ice melted (m) we start by determine the volume of the water generated when the ice melted. This is the difference between the final volume (v2) and the initial volume (v1). Using the density of water (1.0g/mL)‚ this volume can be converted into mass

reunite with them‚ it feels like your first time. Well that’s me with my delicious Grandma’s sweet peanut butter cookies from scratch. No matter how many times I eat them it always feels like their new to my taste buds. I will never forget the day my taste buds was in for a surprise. As I approach the turn to my Grandmother’s house‚ my stomach turns in the anticipation of the perfectly sweet peanut butter cookie smell that awaits. As my mother turn up the long narrow gravel road and parked the

History of Solar Energy 1767‚ First Solar Collector In the year 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector – an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely known as the first solar oven‚ reaching temperatures of 230 degrees fahrenheit. 1839‚ Photovolataic Effect Defined In 1839 a major milestone in the evolution of solar energy happened with the defining of the photovoltaic effect.

NUCLEAR ENERGY Nuclear energy is the energy contained in the centre ‚ or nucleus of an atom. The nucleus is the most powerful source of energy that exist. Nuclear energy is use in scientific research and in medicine treatments. It powers satellites and submarines‚ and it is used to produce electricity. People have also put nuclear energy to destructive uses through the creation of weapons.1 Nuclear energy also called ATOMIC ENERGY‚ energy

Shakespeare noticed that although people respect conventional values much of the time‚ they sometimes learn to develop techniques that enable them to counteract the effectiveness of the values and laws and drift towards illegitimate behavior. In Act iii‚ Scene iii is where Shakespeare shows the turning point of Othello through the implementation of Iago’s plot. Othello’s strong demeanour is now shaken as he is seduced by Iago’s lies and claims them as the truth from an honest old friend. According to Van

lab‚ we are now able to calculate the molar heat of combustion for paraffin‚ since we have the difference of the mass in candle before/after and the periodic table of elements (for converting g to moles of paraffin). Molar heat of combustion = (kJ of heat)/(mole of fuel) However‚ we do not know how much heat was released nor the mole of fuel (paraffin). In order to find the amount of heat released‚ we use the formula: g=mcΔT. Here‚ g represents the heat‚ m represents the mass of water‚ ΔT represents

HEAT TRANSFER MECHANISMS Heat energy is being transferred from one location to another because of a temperature difference. The three mechanisms for heat transfer are: • Conduction. When you grip the hot handle of a pan on a stove‚ you feel conduction in action. Heat flows from the pan and along the length of the handle to its cooler free end. This is because one end of the rod is held at the high temperature‚ and the other end stays at the lower temperature. Although the rod itself doesn’t
