thermometer and placed in a Thiele tube filled with oil. The tube was heated by a Bunsen burner at approximately 1 °C per minute. Melting point temperatures were recorded at the first indication of fluid and then when the sample had turned completely liquid. Two trials were completed on each sample ². The melting point of 10% naphthalene / 90% Biphenyl mixture was determined by electronic instrumentation. Two samples were prepared and placed in closed end capillary tubes and then inserted into

They are formed with the paint mixture pre-added while making the body. * Nano polished Vitrified Tiles : a layer of liquid silica on vitrified tiles then which fills the micro (nano) pores on the tiles surface and makes it smoother in feel. * Glazed Vitrified Tiles(GVT) : vitrified tiles with glazed surface; it is called Glazed Vitrified Tiles (GVT).

Take this opportunity to check the air filter for dirt and liquid. Typically check the air filter every two to three oil changes. It is a good idea to note brake fluid‚ power steering fluid and washer fluids levels before moving underneath the car to drain it. Having checked all the fluids and minor

Butter lab 1 Introduction: While doing this experiment we used 3 terms. We used cream‚ butter‚ and butter milk. Cream is unhomogenized butter. Butter is what we got after the lab was finished. Butter milk is the milk around the butter after it is homogenized and it is thicker than normal milk. If we shake the cream in a jar than will it turn into butter? If I shake the cream than it will turn into butter because it will homogenized. In this lab you will shake a jar of cream and see if will

Melting Ice * Salt is routinely used to make icy roads and sidewalks safe in the winter. As soon as the salt comes in contact with the ice‚ the surface of the ice starts to melt. This only works‚ however‚ if the temperature outside is at or near freezing. If it is too cold outside‚ the ice itself becomes very dry and salt is not as effective in melting it. Salt Reduces Freezing Temperature of Water * Salt works by lowering the freezing temperature of water. Salt water needs to reach a colder

"Diffusion - How atoms move through solids" Diffusion means mass transport by atomic motion. The mechanisms of Gases & Liquids is known as random (Brownian) motion and for solids is known vacancy diffusion or interstitial diffusion. Simply we can define diffusion as‚ the movement of particles in a solid from an area of high concentration to an area of low concentration‚ resulting in the uniform distribution of the substance. (Diffusion chapter 5‚ 2008‚ p.1) Ronald D. Kriz(1999) suggests that

In “To Paint a Water Lily‚” by Ted Hughes‚ the speaker examines the complex aspects of nature by revealing the challenges he faces as an artist in capturing its real meaning. When he looks at the scene‚ he sees an exciting little world of constant movement and activity‚ hidden by the peaceful stillness of the water lilies that float at the surface of the pond. Ted knows that to paint the water lily and do it righteousness requires more than a simple description of the plant itself—he must also somehow
