    Abstract Different substances react in various ways when exposed to heat. The amount of energy necessary to heat a certain amount of water by one degree is different than that of another liquid or substance. The technical term used to determine this characteristic is called heat capacity or specific heat capacity. The purpose of this experiment is to find the heat capacity of water‚ orange juice‚ and olive oil. A couple of very specific equipment is needed in order to complete this experiment

    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:
