COLLEGE OF SCIENCE UNIVERSITY OF THE PHILIPPINES‚ DILIMAN QUEZON CITY‚ PHILIPPINES RECEIVED NOVEMBER 20‚ 2012 INTRODUCTION Heat is a form of energy that can be passed from an object with high temperature to an object with low temperature. The heat required to change the temperature of a substance by 1 K is called heat capacity. A calorimeter is a device commonly used to measure the amount of heat that may be produced or assimilated by the system. This device encloses a reaction inside

Determination of a Rate Law and Temperature Dependence of a Rate Constant By Marvin Coleman March 7‚ 2011 Abstract: From the shown calculations & graphical analysis‚ the experimentally determined rate law is rate = K[I-].969 [H2O2].991 and the experimentally determined activation energy is 59.50 kJ/mole. Introduction: The rate of a reaction varies at different temperatures and reactant concentrations. In this experiment‚ the orders and dependence of the rate constant of the products

Third the earth is not the only planet that has had a change in temperature over the past few years‚ other planets have also had changing temperatures. I belief that global warming is caused by natural things and not humans. The first reason why I belief humans are not the cause of global warming is that the earth

Lab #1: Melting Points of Organic Compounds Report Form May 15‚ 2014 1. A “Melting Point Range” refers to the range of temperature at which a solid melts into its liquid state. 2. Pure compounds have narrow or ‘sharp’ melting point ranges‚ 1°C or less if the compound is very pure. A less pure compound exhibits a broader melting point range‚ between 3°C to 10°C as well as a depressed or lower range. 3. Crushing the sample allows for greater surface area-to-volume ratio of the powder‚ this

thermometers are used for measuring human body temperature‚ with the tip of the thermometer being inserted either into the mouth under the tongue (oral or sub-lingual temperature)‚ under the armpit (axillary temperature)‚ or into the rectum via the anus (rectal temperature). CLASSIFICATION BY TECHNOLOGY Liquid-filled The traditional thermometer is a glass tube with a bulb at one end containing a liquid which expands in a uniform manner with temperature. The tube itself is narrow (capillary) and has

Did you know that if sea levels rise 63cm‚ 130 million people will be flooded per year due to the low lying islands and coastal communities? That our own Great Barrier Reef is already experiencing bleaching due to the 0.4 degree increase in water temperature? Need I go on? We need to stand together as a nation and embrace the fact that climate change is real and needs to be laid to rest with the help of the world to ensure the prosperity of our planet for future generations.
