Fundamental physics concepts

Purpose: The lab was performed for the purpose of calculating the density of each type of object and determining if calculating the volume, and therefore the density, of two cubes can be more effectively done with a ruler (through the direct method) or by water displacement. Materials: 1 Scale 1 Rock 2 Corks 2 Aluminum Cubes 4 Paper clips 2 Marbles 1 50 mL graduated cylinder 1 25 mL graduated cylinder 1 Calculator 1 Ruler Procedure: 1. Weigh and record the mass of each pair of objects (only use

St. Francis Preparatory School Timothy Chung Chemistry Lab #3 Submitted: Thursday, October 16th, 2014 Lab #3: Determination of the Heat of Fusion of Ice Scientific objective: The aim of this experiment is to understand the heat of fusion process and to determine the energy (J) to melt 1.00g of ice. Introduction: Heat of fusion is defined as the energy required changing a substance from solid to liquid without changing its temperature. A common example of heat of fusion is when ice is melted

This experiment was dealing with the heating of water with different types and sizes of metals. In it you had to deal with heat capacity. Heat capacity is the amount of heat (normally expressed in calories, kilocalories, or joules) to raise a substances temperature by one (1) degree (normally expressed in Celsius or Kelvin). With the answer expressed in units of thermal energy per degree temperature. With substances having certain specific dimensions you can use to types of heat capacity, Molar Heat

what I found most surprising was nothing. All the information was merely built upon concepts we had learned previously in class in relation to the ideal gas law and discussed things that I had learned in high school in regards to partial pressure.

Purpose: -To understand Boyle’s and Charles’ theory. -To explain the relationship between temperature, and pressure of a gas. - To explain how the pressure in a container of gas is affected when the volume is changed. Hypothesis: I predict that as the temperature increases the speed of the molecules will increase, causing more kinetic energy to occur, resulting in a greater amount of pressure. As the temperature decreases the speed of the molecules will also decrease, causing less kinetic energy

of Naphthalene from the data collected during the experiment for both the naphthalene section and the benzoic acid section of the experiment. Also, it was very beneficial to actually seeing the experiment being conducted to accurately grasp the concepts correctly and to understand what was actually happening rather than just using a simple equation and plugging in numbers. Using a Parr 1341

1. Does the force or torque in drilling change as the hole depth increases? Explain. How then, would you then change the feeds and speeds as the hole depth increases? Generally, as the hole depth increases, the force or torque in drilling also increases because as the depth increases, the surface contact area will also increase which increases the required force to drill the hole. Therefore, it increases the required torque. As the hole depth increase, the feed and speed reduce because the drill

to come up with an idea for the physics around campus paper. As I saw the burner heat I thought to myself that it seemed like a resistor. And since the burner was changing color and increasing in heat that meant that there must be a current running through the device, which in turn was heating the burner. Following this thought I remember the first two tests of my physics class, which had dealt with both heat and electricity, and therefore, the idea for my physics around campus (or the house) idea

Introduction The purpose of this experiment was to design a calorimeter that successfully converted the energy from the combustion of the chip into heat to increase the temperature of the water. By measuring the temperature in the water from the beginning to the end and converting it into joules to see how much energy the water captured, we were able to complete the experiment. Literature review Energy is a very important property, it can only be conserved. Energy can’t be created or destroyed

Can I ask all of you to please close your eyes? Now imagine coming home from work and visualize you seeing a group of large, black and white whales eating all kinds of pastries outside of your house. Now I need you to see this. They are dropping chocolate and jelly filling everywhere. Then, you go back inside of your house and you appreciate the quality of the light. This light shines on glittering white Olaf the Snowman. He is dancing on your coffee table, partying his heart out, slowly melting
