A microwave oven works by generating electromagnetic radiation that can be absorbed by water molecules causing them to rotate faster. The friction of the rotating water molecules is lost to their surroundings, thus heating up the food you place in the microwave oven. A microwave oscillator (thing that makes microwaves) emits radiation at a wavelength of 12.24 cm. What is the minimum time it will take a 800 Watt (i.e. 800 Js4) microwave oven emitting 12.24 cm wavelength photons to heat 100 g of water from 20° to 50°C? The heat capacity of water is 4.18 Jg deg1?

Kinetic-Theory of Gases

Kinetic theory of gases is the model or method which was developed in the 19th century by Maxwell and Boltzmann. This is possible as the interatomic force which is of short-range forces that are important for solids and liquids can be neglected for gases. This theory or gas law gives a molecular interpretation of the pressure and temperature of a gas and is consistent with gas laws and Avogadro’s hypothesis. This theory is very helpful to correctly explain the specific heat capacities of many gases, kinetic energy and it also explains the transport qualities such as viscosity, thermal conductivity, and diffusion with molecular parameters. As stated in the kinetic-molecular theory, the temperature of a substance or gas particle is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles, called average kinetic energy.
