An application of Charles' Law is a floating hot air balloon. A torch heats the air inside the balloon causing the air particles to move faster and disperse, making the air in the balloon less dense than the surrounding air so that the balloon floats.
Charles' Law explains the relationship between the volume and temperature of a gas. It states that heating a gas while holding its pressure constant results in an increase in the volume of the gas. Similarly, the volume of the gas decreases when the temperature decreases.
A hot air balloon is an application of Charles' Law. The fuel used heats the air inside the balloon. Heating the air increases the speed of its gas particles in air, so they move faster and spread out, according to kinetic molecular theory as described by the University of California. This causes the gas inside the balloon to take up more space.
The speed of movement of the gas particles as well as their dispersal causes the air inside the balloon to become less dense than the air surrounding it. As a result, the balloon floats. In short, the hot air in the balloon rises because of its decreased density.Learn More
Hess’s Law states that the total enthalpy of a system stay the same throughout a chemical reaction whether said reaction is comprised of one step or of many steps. It is a common relationship in physical chemistry that describes the differences in reactants and products throughout chemical reactions. Hess’s Law was named after Germain Hess who published the law in 1840.Full Answer >
The ideal gas law describes a relationship between pressure (P), volume (V), temperature and number of moles (n) in terms of the gas constant (R) for an ideal gas. The ratio of (PV) to (nT) should be equal to the gas constant as shown in the ideal gas equation PV = nRT. The ideal gas law assumes that the gas molecules are ideal and do not have any volume and that there are no forces acting on them except during collisions. It was designed to understand the effects of pressure, volume and temperature on gases while excluding the variables of real-world conditions.Full Answer >
Boyle's law, the principle that the pressure on a gas is inversely proportional to its volume at constant temperatures, is demonstrable with everything from balloons to soda cans to SCUBA gear. Aerosol cans and syringes both rely on Boyle's law in order to perform their functions as well.Full Answer >
An example of the law of conservation of mass is the combustion of a piece of paper to form ash, water vapor and carbon dioxide. In this process, the mass of the paper is not actually destroyed; instead, it is transformed into other forms. This best demonstrates the law that states matter cannot be created or destroyed. However, the form of matter can be changed.Full Answer >
