    volatile liquid can be easily converted to its gaseous state, the gas that forms from vaporization is known as vapor and it is assumed to behave as an ideal gas. One of the properties that characterize a volatile liquid is determination of its molar mass. Dumas method also known as the vapor density method uses the vapor density of the unknown volatile liquid in determining its molar mass. The major assumptions of these methods are the substance behaves ideally. The molar mass of a volatile liquid can

  • Glaze Ice Formation Essay

    1733 Words  | 7 Pages

    This ice formation, which is less dense then glaze ice, is an opaque, rough deposit. At ground level it forms in freezing fog and consists of a deposit of ice on the windward side of exposed objects. Rime is light and porous and results from the small water drops freezing as individual particles, with little or no spreading. A large amount of air is trapped between the particles. Aircraft in flight may experience rime icing when flying through clouds with the air temperature and the temperature

  • Self-Design Lab Report

    1153 Words  | 5 Pages

    The Affect Different Liquids have on Dry Ice’s CO2 Release I. DESIGN: How long does it take a piece of dry ice to sublimate in different liquids? Background Theory: Dry ice is the solid form of CO2, therefore it sublimates instead of melts. Sublimation is a solid turning into a gas instead of a liquid. When placed in water, dry ice reacts by sublimating faster because of the added temperature. Eventually, the entire piece of ice will be sublimated, but different liquids could change the time

  • What Is The Molar Mass Of Cyclohexane Experiment

    1022 Words  | 5 Pages

    Purpose The purpose of the experiment was to determine the molar mass of unknown solute number 1. This was done by using colligative properties of solutions specifically, freezing point depression. Colligative properties depend on the number of molecules that are present in the solution rather than the nature of the molecules [1]. This fact is useful because knowing this allows one to use the properties of the number of molecule in the solution without needing to worry too much about the nature

  • Effects Of The Mmamba Experiment

    773 Words  | 4 Pages

    It didn’t make any sense. Although, in 2013, physicists found out why this strange effect takes place. It has to do with the chemistry of each individual molecule. “When water heats up, the hydrogen bonds stretch and store energy as the liquid gets less dense and molecules move apart. The extra stretch in the bonds allows the bonds between molecules to relax and shrink a little, giving up their energy. This is equal to cooling.” What this explanation basically means is that superheating

  • Research Paper On Snowboard

    898 Words  | 4 Pages

    Introduction: When a snowboard is “waxed” this means that performance grade ski wax is melted by a hot iron onto the base of the snowboard and spread out evenly. This wax fills the tiny cuts and scraps of the polyethylene base, that snow tends to stick to, and creates a smooth surface. This helps protect the base of the snowboard from being worn and makes the board glide over snow easier. The purpose of this guide is to instruct beginner level snowboarders how to apply wax to the base of their

  • The Mpemba Effect Speech

    1148 Words  | 5 Pages

    The Mpemba Effect is the observation that warm water freezes quicker than cold water in certain circumstances. Warm water seems counterintuitive, but ultimately catalyzes the freezing process. In this analogy, the warm water represents disobedience and the freezing process represents social progress. Disobedience has a negative connotation, which contradicts the idea of positive progression, but in many cases, can actually accelerate it. Many commonly misinterpret disobedience as violence, when

  • Why Objects Fall In Fluid's Viscosity

    373 Words  | 2 Pages

    After the experimentation, you may ask yourself “Why did all of these spheres fall at a different rate when Galileo said that objects fall at the same rate (in a vacuum)?” The reason why the objects fell at a different rate in the fluids given was because the fluid’s viscosity varies. The viscosity of a fluid can impact an object that you drop into it, because there’s a resistance of some sort impacting the rate of which they fall. For example, when both spheres were dropped at the same time into
