PHYS1110 Lab report: “Why does your kettle boil”. To do this investigation‚ I agree that I will follow all the risk control methods and conduct the experiment in a very safe condition. The aim of this investigation is to find out more about boil water by using a kettle. For example‚ time taken to boil different volumes of water‚ specific heat of water and power of kettle. Equipment: This picture shows all the equipment that I used to do the experiment including a stop watch‚ a measuring

CHAPTER 5 STATES OF MATTER INTERMOLECULAR FORCES Intermolecular forces are the forces of attraction and repulsion between interacting particles (atoms and molecules). Attractive intermolecular forces are known as van der Waals forces. van der Waals forces include dispersion forces or London forces‚ dipole-dipole forces‚ and dipole-induced dipole forces. A particularly strong type of dipole-dipole interaction is hydrogen bonding. Dispersion Forces or London Forces Observed between non-polar molecules

Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube‚ shiny foil can be used because it’s a poor emitter of radiation and it will reflect escaping heat by reflecting‚ because this method is used in flasks to keep hot drinks warm. Though it is a good conductor so will lose heat through to surfaces its touching but it shouldn’t matter because it will be touching air and glass which both

HVAC 101 Definitions Atom – Is the smallest particle of an element. BTU – The amount of heat required to raise the temperature of 1lb of water 1 degree F Molecule – The smallest particle that a substance can be broken into and still retain its chemical identity. Conduction – Is energy that travels from one molecule to another molecule. Convection – To move heat from one location to another be means of current set up in a fluid medium. Density – The weight per unit of volume of a substance.

Mofu Lin Ms. Conte 15/3/12 IB Chemistry Soda can calorimeter(Energy content of food) Lab report Introduction We‚ human needs energy to live and for movements. Thus‚ we eat and combust food to release its heat energy in our bodies. In this experiment‚ we will determine how much heat energy released when we eat snack foods such as popcorn or potato chips. This lab includes three burning tests of different foods with different energy contents. Calorimetry is the science associated with determining the

Homer Gere Science - Perry 7-3 Kober Balloon Lab Report Problem: The goal of the balloon lab was to get a balloon attached to a line all the way across the room. One limitation was that we could only use one balloon‚ two straws‚ and tape. The circumference of the circle at its largest point couldn’t be larger than 100 cm. Procedure/Results: Trial Number | Distance Traveled (CM) | Time (sec) | Velocity (CM/sec) | 1 | 346 | 1.02 | 339.2 | 2 | 471 | .79 | 596.2 | 3 | 356 | .8 |

Change in Pressure and Different Depths in a Static Fluid Lab Marcus Uchaker MET: 2050 January 26‚ 2012 Purpose: The purpose of this lab is to devise a correlation between that of the data we have collected from our experiment and compare it to that of theory. In this experiment 3 different tests were done in order to test this theory. The first test was to tie a balloon on the end of a manometer and measure the pressure at different depths in a large beaker filled with water. The next

2. First stage of Martens’ model of competition is Objective Competitive Situation: This means that without a witness or another person present then you cannot have proper competition. An example of this would be you running a mile at the track and you want to run this mile under 5 min. You have a friend there recording your time and you tell him you want to run under 5 min. This would be considered competition based on Martens’ thought on Objective Competitive Situation. Second in Martens’
