Cashew Experiment and Temperature Changes

The video tutorial demonstrates an experiment where a cashew is burned to heat water. Initially, 100 milliliters of water is measured at 20 degrees Celsius. The cashew is then set on fire, and after it burns out, the water's temperature is measured again, reaching 44 degrees Celsius. The change in temperature is used to calculate the calories of heat energy transferred to the water from the burning cashew.

What is the main objective of the experiment described in the video?

• To calculate the density of cashews

• To determine the freezing point of water

• To observe the burning properties of cashews

• To measure the boiling point of water
