Formal Report on Heat Capacity Ratios of Gases

AbstractThis report discusses an investigation of the fire up capacities of Helium, Nitrogen, and Carbon Dioxide. To accurately resolve experimental values for the combust readiness of all(prenominal) gas, the incite energy readiness ratio was calculated from measurements of the advance of infiltrate in each gas. An apparatus designed to measure the wavelength and absolute frequency of belong waves in each gas was used to look into the speed of sound as a frequency was passed finished each gas. The apparatus consisted of a Kundt?s tube, an osilliscope, a ruler, an sound oscillator, and a frequency counter. The experimental values of rage cogency were ar disgorge to agree with the theoretical values within the range of uncertainty. This experiment conclusively demonstrated an accurate method of find out the light subject matter of a gas. IntroductionTo determine the heat capacity of a gas, one fuel first determine the heat capacity ratio, via the speed of s ound with that gas. One tail end bedevil an intuitive grasp of the fact that heat capacity varies from midpoint to substance based upon this relationship. If two kids are acting near at the railroad tracks they give the sack perform a truly simple demonstration of the speed of sound through different media.

If one kid stands at a federal agency of capacious distance along the tracks from the other and simultaneously screams as he hits the tracks with a hammer, the observer will notice that he can hear the sound from the hammer on the tracks forwards he hears the scream. This is because the metal in th e railroad tracks has a high heat capacity ! than air. For a substance, if the molecular mass, the speed of sound through that substance, and temperature of a gas is known, the relationship between them can succumb a ratio which is directly proportional to its heat capacity.
