Energy is the ability to perform work. There are many kinds of energies: kinetic, potencial, electromagnetic etc. Energy is measured in joules.
Count Rumford found out that heat is a kind of energy.
Temperature in contrast is a sense of the hotness and coldness in an object.
We can measure energy using the equation Heat=mass times specific heat times change in temperature.
Specific heat is the amount of heat an object is able to absorb to raise the temperature of 1 gr by 1 degree. Different objects have different specific heat.
In our experiment we had the same amounts of oil and water in two different containers (100 ml). We measured the temperatures and recorded them in the computer. Then we heated the objects and recorded their temperatures again. We found the average temperature. We subtracted the final temperature by the initial temperature to find the change in temperature and plug it in the equation. The temperatures of oil and water differed. Oil had the biggest temperature because it has a lower specific heat. Water had a lower temperature and a bigger specific heat. Then we found the heat in joules using the above equation.
We didn’t get an exact result because some of the heat was lost during the experiment. The heat was supposed to be the same for both containers because they absorbed the same energy.
