  • Essay On Chocolate Melting

    822 Words  | 4 Pages

    Introduction: Melting is the change of a solid into a liquid when heat is applied. Melting will occur at a fixed temperature which known as melting point. Melting point is the temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. The temperature will increase until the melting point is reached when heat is applied. Heat will convert the solid into a liquid with no temperature change. Temperature of the liquid will raise when the entire solid has melted

    Did you know that around 218 million people die each year from natural disasters? Some people don’t even know that some of the common natural disasters can possibly happen in their very own back yard. These disasters are way more powerful than they may seem; they can tear down houses, wipe out forests, and split the earth's crust in half. I bet you wish there was a way to stop the terrible disasters from killing all of these innocent people but, sadly, you can't. Scientist can predict when some of

  • Le Chatelier's Theory

    800 Words  | 4 Pages

    INTRODUCTION The concept of chemical equilibrium was developed after Berthollet (1803) found that some chemical reactions are reversible. For any reaction mixture to exist at equilibrium, the rates of the forward and backward (reverse) reactions are equal. In the following chemical equation with arrows pointing both ways to indicate equilibrium, A and B are reactant chemical species, S and T are product species, and α, β, σ, and τ are the stoichiometric coefficients of the respective reactants

  • Lava Lamp History

    910 Words  | 4 Pages

    In 1963, Edward Craven Walker invented a colorful, bright, and soothing item called the lava lamp, or previously known as the “Astro Lamp”. It was inspired by an egg timer sitting on a kitchen stove filled with two liquids bubbling because they were unable to mix. He enhanced on this by making it into a radiant lamp that is still being used around the world today! What is a lava lamp made of? A lava lamp is made up of two components: a wax compound and a liquid compound (such as water). The concept

  • Essay On Fractional Distillation

    740 Words  | 3 Pages

    What is fractional distillation? Fractional distillation is a method of separating miscible liquids using heat. This technique is used for the separation of liquids which dissolve in each other. Several simple distillations are completed during fractional distillation using only one apparatus. During the process a mixture is separated into several parts called fractions. Mixtures contain different substance with different boiling points, the differences in boiling points is the main reason fractional

  • Explain The Volume, Temperature And Pressure Exerted By Several Gas Laws

    952 Words  | 4 Pages

    pressure exerted by a particular gas are highly dependent on one another. This is explained by several Gas Laws. Boyle’s Law states that when the temperature is kept constant, pressure of gas is inversely proportional to the volume. Relating this principle to molar volume, the higher the pressure, the smaller the volume the gas particles occupies. When the volume of the container enclosing the gas is reduced, there are more gas particles per unit volume. The gas particles collide with each other

    Chapter -1: OBJECTIVE the more general When designing a small temperature control system, the best choice for a refrigerator/heater element is often a thermoelectric cooler (TEC). The operation of these devices is based on the Peltier effect, which was discovered in 1834 by Jean Peltier. When an electrical current is passed through the junction of two dissimilar metals (Figure 1), heat is also transferred across the junction. To pump heat, a thermoelectric cooler can require a significant amount

For gases the density may amount with the number of gas molecules in a constant volume. Helium balloon: Compare the behavior of helium filled balloon with that of an air filled balloon. Even taking into account the weight of the rubber balloon, the helium balloon floats on the air and is less dense than

  • Hot Water Vs Cold Water Essay

    1472 Words  | 6 Pages

    Abstract— “An explanation for why hot water will sometime freeze more rapidly than cold water is offered. Two specimens of water from the same source will often have different spontaneous freezing temperatures; that is, the temperature at which freezing begins. When both specimens supercool and the spontaneous freezing temperature of the hot water is higher than that of the cold water, then the hot water will usually freeze first, if all other conditions are equal and remain so during cooling. The

  • Effects Of The Mmamba Experiment

    THE MPEMBA EFFECT Erin Splaine Deerfield School Grade 8 Abstract The reason for this experiment was to find a faster way to freeze water by simply changing the temperature. The way this was accomplished was by heating an amount of water while leaving an equivalent amount at room temperature, then freezing both amounts of water and determining which freezes first. The heated water ended up freezing completely first, even though the cooler water started to freeze first. These findings tell us that
