A curiosity since I was a child When I was a child I visited an ice cream factory with the school in summer. We entered in the freezing room and we felt really cold. Have you ever visited a freezing rom? A freezing room is a close room in the factory where we need very low temperatures to conserve food. My question was, how was cold in that room if we was in summer? Then in my house I don’t understand how the freezer works and a lot of things like the regulation of the water in the bathroom. For looking answers I studied a lot of subject about physics in the secondary school but I didn’t study subjects about thermodynamics. A few years later, I studied Industrial Engineering at University and finally I studied a lot of subjects about thermodynamic. Do you know something about thermodynamics? Thermodynamics is a brunch of physics concerned about the heat transfer. It defines variables like the temperature, the pressure and the volume Actually I work in a factory about automobile air conditioning and I love my job because the cold was a curiosity since I was a child.
