Chemistry For You by Laurie Ryan‚ it states "As you increase the concentration of the acid‚ there are more acid particles in the same volume. Therefore there is a greater chance of acid particles colliding‚ and reacting with more particles on the surface of the marble." So‚ this means that the higher the concentration of my acid the faster the reaction. Method I will weigh out one gram of marble chips using a balance and put it in a conical flask and add to it a concentration of 50cm3

project is on the surface tension of water and what affects the surface tension of water. The question that I am going to ask is how does temperature and salinity of water affect the surface tension of the water. My hypothesis is that the colder and the saltier that the water is‚ the stronger that the surface tension of the water will be. Some of the background research that I have done has explained to me that the surface tension of water is a property of a liquids surface that can cause it to

stream of vapor-free gas is passed. A water bath is provided for maintaining a steady temperature so that there is no eddy current in the vertical tube and mass transfer takes place from the surface by molecular diffusion alone. The rate of evaporation can be followed by the rate of fall of the liquid surface. A traveling microscope is provided for determining‚ the liquid fall. With the knowledge of the concentration gradient‚ the diffusivity of the vapor of the volatile liquid can then be calculated

probes successfully landed on the surface of the Venus. However‚ the essential equipment on probes was damaged‚ leading to that it failed to get insight into the surface of the Venus. While‚ on 17th August 1970‚ with the experiences from the previous two attempts‚ "Venus 7" lander completed their missions on the surface of the Venus successfully. The lander gauged the atmospheric pressure on the surface of the Venus‚ which illustrated that the pressure on the Venus’ surface was at least 90 times stronger

perpendicular to or normal to the section is called the normal stress. Normal stress may be tensile or compressive. Tensile stress: stresses that cause pulling on the surface of the section‚ (particles of the materials tend to pull apart causing extension in the direction of force) Compressive stress: stresses that cause pushing on the surface of the section‚ (particles of the materials tend to push together causing shortening in the direction of force) Strain • If a bar is subjected to a direct

energy that travel through the earth‚ and are a result of an earthquake‚ explosion‚ or a volcano that imparts low-frequency acoustic energy. There are two types of seismic waves‚ Body waves and surface waves. Body waves travel through the interior of the earth. Surface waves travel along the earth’s surface and through water. Seismic wave fields are measured by a seismograph‚ geophone‚ hydrophone or accelerometer. These are used to measure earthquakes. When measuring these earthquakes these
