bond. The radius varies with the location of an atom on the atomic chart‚ the type of chemical bond‚ the number of neighbouring atoms (coordination number) and a quantum mechanical property known as spin. On the periodic table of the elements‚ atom size tends to increase when moving down columns‚ but decrease when moving across rows (left to right). When subjected to external fields‚ like an electrical field‚ the shape of an atom may change from that of a sphere. Atomic dimensions are thousands

Maximum Cell Size & Diffusion – Ferris Shaw Research Question: How does the surface area to volume ratio affect the diffusion rate in agar cubes? Hypothesis: The rate of diffusion in directly related to the surface area to volume ratio of cells and is responsible for the efficiency of absorbing nutrients‚ oxygen‚ minerals etc. in the cell. This ratio is specific to cells as they require a ratio that isn’t big enough to take too long to receive the nutrients and oxygen or too small to

Sample size The process of determining the proper sample size was established through a series of calculations and after obtaining all the possible sample sizes‚ the largest one was taken into consideration to collect the closest number to a representative sample of the population. The following two equations where used: Equation 1: N=z2 *(p.q) E2 N= sample size Z=level of confidence interval at 95% so z=1.96 P=estimated percent of population E=acceptable sample error expressed

This refers to the type of pollution that enters our rivers through direct drainage pipes‚ and the problem has been visibly decreased all over the country. This may seem like

Size reduction and screening The purpose of this experiment was to determine the affect of vibration rate and time on the size reduction and size separation of particles. The objective was successfully completed and the initial sample of soil was separated by vibration into finer particles with a large amount passing through the smallest diameter screen which was 0.0278 inches producing a final product of fine soil particles which are now easier to transport and store. As can be seen from the
