Aim: i) To find the relationship between supplied energy and change in temperature of water. ii) To find the specific heat capacity (SHC) of water. Hypothesis: As time increases so does the temperature since the water is exposed to the heated wire for a longer period of time. Variables: The Dependent Variable is the temperature of the water‚ and since the Energy is calculated using temperature it is a dependent variable as well. The constant variables are the voltage and current. Theory:

Specific Heat Lab Report “Here are the facts we confront; No one is against conservation. No one is against alternative fuel sources.” – J. D. Hayworth Research Question: Does the number of hydrocarbons that a fuel is composed of affect how much it will ignite? If so‚ consider the following: What is the quantity and concentration of the combustion that is released and how can that be measured in other (more coherent) means? These are the fuels that were seasoned throughout the

Heat exhaustion: This condition often occurs when people exercise in a hot‚ humid place and body fluids are lost through sweating‚ causing dehydration and overheating of the body. Temperature may be elevated‚ but not above 104 F (40 C). Occurs when not well adjusted to heat exercise. At high temperatures‚ the body cools itself largely through evaporation of sweat. When humid‚ this mechanism does not work properly. Body loses a electrolytes. When this is accompanied by an inadequate replacement of
