essential in all studies of soil mechanics. To sight a few‚ natural moisture content is used in determining the bearing capacity and settlement. The natural moisture content will give an idea of the state of soil in the field. Apparatus: 1. Containers (Tin or Aluminum) with lids. 2. Balance‚ sensitive to 0.01gm 3.

ii) liquids > vibrating particles have sufficient energy to move from their fixed positions to other parts within a liquid. > liquids take the shape of their container. iii) gases > particles have sufficient kinetic energy to help escape the attractive forces from other particles. > gases take up the complete volume of a container. The kinetic theory provides vital information on the sciences we learn. An example of this is the topic on "heating and cooling" in physics. Besides‚ the kinetic

If there is a stop in the system that would prevent anyone from drinking‚ eating or cleaning – it would be a great problem. So to get rid of these problem containers can be used. There are a lot of free containers found in the shops made from the highest-grade plastic and polyethylene. Whether you live in an apartment or in the largest mansion‚ a container work for you anytime anywhere. There

Procedure for mixing concrete 1. Weigh out the designed proportions for a 1.6 cubic foot batch of concrete. a. Divide the water into two buckets‚ one with about 3/4 of the water. If using air entraining‚ put the air entraining agent in the 3/4 water bucket. 2. Put about half the coarse aggregate‚ half the fine aggregate and the 3/4 bucket of water with air entraining in the mixer. 3. Start the mixer and mix until the aggregate is thoroughly wet 4. Carefully add all the cement with the mixer

Moving the lid up or down will change the volume inside the container. You will use an attached manometer to measure the pressure inside the container. Procedure: 1. Move the lid of the container up or down. Record the resulting volume and pressure inside the container. 2. Continue this process until data is obtained for at least six different volume and pressure

evaporation of water in different sized containers. By measuring the time it takes for the whole amount of water to evaporate‚ a conclusion can be made about the validity of the surface to volume ratio in regards to the biological process of diffusion. Research Question: What is the effect of the surface area to volume ratio on the evaporation of water? Variables: - Independent: o Surface area in cm2 of the top most surface of water in the container. - Dependent: o Rate of evaporation in

The hospitals mentioned suffer a severe lack of medical waste management awareness on all levels‚ it is noted that the most important priorities in the management of hospital waste is the "Treatment of the Medical Waste " created in those medical centers‚ implementing a proper and a safe way for both humans and environment. Hospitals are one of the main creators of medical wastes which are dangerous. Collection‚ storage and final disposal of these wastes has been and remains to be a stern issue

Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around
