How does lava temperature impact viscosity and velocity? The higher the temperature the lower the viscosity which allows it to develop a smooth surface skin‚ but this is quickly broken up by flow of molten lava‚ it creates a rough‚ clinkery surface. The lower the temperature of the magma the higher the viscosity which allows the lava to travel down the slope. In the group the average velocity was 0.91 cm/s . How the “lava” flowed was in a high viscosity and a low velocity because the “lava” was

If the earth was at an axial tilt of 0° there would be absolutely no seasonal change‚ the temperature would remain even at all times of the year. The temperature around the equator (0°latitude) would be about 40°C or 104°F‚ and the 80°N latitude would be at about -35°C or -31°F; with the temperatures remaining this way all year round and no seasonality migration and aggregation of the poles would be mythical; also would be too cold for reproduction hence no “annual flush of productivity.” In the

Assignment Topic 2 AUD/USD Exchange Rate The main movements of the AUD/USD exchange rate in the past eighteen months will be studied‚ as well as the underlying conditions that caused these specific movements to happen. Economic models and theories will be used to support the discussion and to analyse the reason for these fluctuations. Discussion will then take place to whether these movements have been a help or a hindrance to the overall health of the Australian economy. FIGURE 1.0

Pulse rate During the practical while at rest the pulse is at a normal speed as the person is not doing any activity which requires lots of energy. This changes when the person starts to exercise as the line on the graph increases‚ this shows that the pulse rate is increasing because the heart is beating faster to make sure enough oxygen reaches the cells‚ this also causes the breathing to increase as the body has to take in more oxygen to supply the body and remove the carbon dioxide. In the body

factors which can have an effect on the process of photosynthesis; in this laboratory experiment‚ the focus lies on carbon dioxide (CO2) availably and its effect on photosynthesis. By understanding the component that affect the rate of photosynthesis‚ one can do work to try and increase the rate of photosynthesis. The purpose of this laboratory experiment was to determine which solution would have the highest impact on oxygen production within the aquatic plant‚ Elodea densa (Brazilian Waterweed). The

28/09/12 Grace Masters Woodlice Behavior Experiment Aim: To investigate the effect of light intensity on the behavior of woodlice (Porcellio scaber) in regards to their change in speed. Variables: Variable How can it be controlled? (IV) - Light intensity - The light intensity will be controlled by the knob on the lamp throughout the experiment. In addition‚ the light intensity will be controlled by closing the windows and doors in the classroom as well as turning

How does the Amount of CO2 Affect the Rate of Photosynthesis? There are a number of variables that can affect the photosynthesis rate of Canadian water weed (Elodea). They are as follows:  The amount of light: an increased light level increases the rate of photosynthesis to a certain point where at another factor limits the photosynthesis rate.  The temperature: Increased temperature increases the rate of photosynthesis to a certain temperature‚ after which‚ essential enzymes

that no milk was added to the coffee within this experiment. If milk was added into the experiment‚ the rate of cooling would be noticeably faster than it is without adding the milk. This would result in larger k values. Also‚ the amount of water that was measured into the beaker may not be accurate due to the fact that human error can come into play. The effect of this would be that the rate of cooling of the coffee may actually be slightly higher or lower depending on whether less or more water

Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane‚ with holes
