And this increases the energy lost to the surroundings in the form of heat‚ which affects the temperature. � PROCESSED DATA Calculations Theory states: ΔH= -Q/n Q = m * c * ΔT � Where in this case m = mass of water‚ c = specific heat capacity of water and T in Kelvin. In order to know whether mass should be in kg or g we look at the c-value. c= 4.18 JK-1g-1. And Q is measured in Joules. J = g * JK-1g-1 * K. m must be in grams since J=J‚ and not J = kJ like it would

My Rhetorical Analysis of "Pit Bull‚ Bum Rap?" In 2004‚ Maclean’s published Lianne George’s essay‚ "Pit Bull‚ Bum Rap?" in regards to a proposal to ban pit bulls. Lianne George is currently an associate editor for Maclean’s magazine in Canada. She has written numerous commentaries such as this one‚ "Pit Bull‚ Bum Rap?" for Maclean’s and other publications like the National Post. Lianne George begins with an overview of dog breeds falling in and out of fashion. She compares the current pit

Specific Heat: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat. The relationship does not apply if a phase change is encountered‚ because the heat added or removed during a phase change does not change the temperature. Q=mcTDelta Abstract: In this experiment we are trying to determine the

The Controversial Installation There are several meanings for the term‚ "art". Art comes in many different forms‚ like paintings‚ sculptures‚ poetry‚ film‚ etcetera. It serves as a vessel for storytelling and projects the relationship between man and its surroundings by utilizing their vision and creativity. Unfortunately‚ society at times fails to understand the meaning and rejects it. There was one particular installation that surprisingly caused controversy. The piece was called the‚ "Tilted

The importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water?
