Page 150 - Archimedes stated that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid.
Page 219 - The heat which is expended in changing a body from the solid to the liquid state, or from the liquid to the gaseous state, is called latent heat.
Page 188 - ... air and the smallness of the tube. The bulb is therefore heated, when the air within expands, and a portion escapes in bubbles through the mercury. On cooling, the pressure of the external atmosphere forces a quantity of mercury through the tube into the bulb. By repeating this operation a few times, the bulb and a portion of the tube are filled with mercury. The whole is then heated till the mercury boils, thus filling the tube, when the funnel is melted off and the tube hermetically sealed...
Page 164 - Sounds are propagated better in calm than in stormy weather, also with more intensity in the direction of the wind than in the contrary direction. A modification of the law, that the intensity of sound varies inversely as the square of the distance, takes place when sound is caused to travel through long smooth tubes. The sound moves like the rings produced in a pool of water by a falling stone: they...
Page 281 - When the object is between the principal focus and the mirror, the image is virtual and erect, as shown in Fig.
Page 112 - TOHRICELLI'S experiment, take a glass tube about three feet in length. closed at one end and open at the other. Turning the closed end downwards, let it be filled with mercury. Then holding the finger over the open end, let it be inverted in a vessel of mercury, as shown in Fig.
Page 284 - ... 1. The planes of incidence and refraction coincide, both being normal to the surface separating the media, at the point of incidence. 2. The sine of the angle of incidence is equal to the sine of the angle of refraction multiplied by a constant quantity.
Page 13 - IMPENETRABILITY is that property by virtue of which no two bodies can occupy the same place at the same time.
Page 435 - Two wires, one connected with the positive, and the other with the negative pole of a...
Page 284 - The angle which the incident ray makes with the normal at the point of incidence is called the angle of incidence, and the plane of this angle is the plane of incidence.
