I. Introduction Pressure is the application of force to a surface ‚ and the concentration of that force in a given area . A finger can be pressed against a wall without making any lasting impression ; however ‚ the same finger pushing a Thumbtack can easily damage the wall ‚ even though the force applied is the same ‚ because the point concentrates that force into a smaller area. Volume is the quantity of three-dimensional space occupied

Differentiate between the significance of the coefficients in a balanced chemical equation and the significance of the subscripts in a chemical formula. · Coefficients show the correct proportions of atoms and molecules in a chemical reaction. They are normal sized numbers placed at the beginning of the chemical formulas in a chemical reaction during the process of balancing. They tell how many of an entire

Life can be so accelerated in many countries. The competition for the best job‚ the best quality of life or simply “a perfect life” of wealth and material things imposed by society as something to envy‚ can cause an enormous pressure on people of all ages. Sometimes‚ mental and physical wellness can be affected by Stress‚ a continuous feeling of worry cause by difficulties in life that prevent people from relaxing and living in harmony. Students are not the exception: they have to combine different

Lab 5Cellular Respiration Introduction: Cellular respiration is an ATP-producing catabolic process in which the ultimate electron acceptor is an inorganic molecule‚ such as oxygen. It is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell. Carbohydrates‚ proteins‚ and fats can all be metabolized as fuel‚ but cellular respiration is most often described as the oxidation of glucose‚ as follows: C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 kilocalories

volume of gas was measured (gasometric analysis). The ideal gas law was then used‚ PV = nRT. Since the volume‚ temperature‚ gas constant (R)‚ and pressure are known‚ the amount of moles of hydrogen can be figured and then converted to mass. The water vapor pressure also was subtracted from the measured pressure in the lab to obtain the correct pressure of hydrogen. The values obtained for the three nails using Gasometric analysis were 0.0815‚ 0.0846‚ and 0.1269 grams. After the stopping point of

Research Question Investigate the effect of temperature on the rate of respiration of various parts of plants (germinating seeds and dormant (non-germinating) seeds)‚ by measuring the oxygen consumption and change in gas volume of respirometers containing either germinating or non-germinating seeds at different temperatures to measure the rate of respiration of these beans at different temperatures. Hypothesis 1.Germinating seeds have a higher rate of respiration as compared to non-germinating
