The Second law of thermodynamics There are four laws of thermodynamics‚ which define temperature‚ energy and entropy‚ characterizing thermodynamic systems. To understand the second law of thermodynamics we should know that on a basic level it explains the “catch twenty-twos” to the first law of thermodynamics. The first law of thermodynamics says that energy can never be created nor destroyed‚ only transferred to another form of energy. The second law states that some processes do not take place

Breaking a Ruler with Atmospheric Pressure Introduction In this experiment‚ I will try to use air pressure‚ along with some sheets of newspaper‚ to attempt to break a ruler. Air pressure is the weight of the atmosphere pressing down on the earth. A device called a barometer measures it in units called millibars. Most barometers use mercury in a glass column‚ like a thermometer‚ to measure the change in air pressure. I came up with this idea from when I read in a book about how some kids tried to

Thermodynamics Section Review 9A: 1. Scientists believed that the caloric was a material but mainly that it was an invisible fluid consisting of self-repelling particles. Two examples include how gases expand according to Newton’s laws‚ and determining the speed of sound in air. 2. The first person to successfully challenge the caloric theory was Benjamin Thompson. Benjamin observed that a dull boring bit could generate more hat than needed to melt the entire cannon barrel. 3. The significance
