Conduction occurs in both solids and liquids when adjoining particles vibrate so that they diffuse heat to one another throughout a space, until all of the particles are the same temperature. Conduction performs a significant role in the lithosphere as this is the place conduction occurs and also as this is where the Earth loses most of its internal heat. Along the mid-ocean ridges where the temperature is significantly high, mainly along the most active and major ridges, the tectonic plates thicken as they move away from the ridges and cool. From this evidence we can see that conduction is an important process as it moves the heat from the upper mantle through the lithosphere to the Earth’s crust. Convection is another method of heat transfer.
In the case of α-phase FePO4, cell parameters tend to increase exponentially as temperature increase. The volume of the metal has the tendency to increase exponentially as well. It is governed by thermal expansion coefficient α (K-1)= 2.924 x 10-5 + 2.920 x 10-10 (T-300)2. There are two factors that affect the thermal expansions: 1. Angular variations due to the changes of Fe-O-P bridging angles.
During the explosion not only are gases produced quickly, but they are also hot, and they expand rapidly, according to Charles’ Law, which states that as the temperature of enclosed gas increases, the volume increases, if the pressure is consistent(Antonis, K. 2010). The chemical reaction the firework puts off is when [a]toms, as well as molecules, come together to form larger molecules, and larger molecules break up(Trefil, 2014). The chemical reaction also depends on the color of the firework. How do Chemists make the colors for Fireworks? When scientists make the different colors, each color has its own element.
'Average temperatures are rising in the world. The rising temperatures may result in physiological and ecological effects on organisms. Describe and explain these effects. (25 marks) The rising global temperatures, are likely to have huge effects on all organisms in the world. This is due to an increased concentration of greenhouse gases.
We then, can assume the reason for the increasing temperature was resulted from industries, over-powering energy with coal during that specified time period. Manufacturing produces massive amounts of carbon dioxide along with other greenhouse gases, resulting in warming the whole planet, hene causes climate changes. Thus, it can be concluded that humans have a strong correlation with the increasing temperature and climate changes that are happening
Enzyme Activity Research Question: Does increasing the temperature of 3ml lipase increase the rate of reaction in enzyme-catalyzed reaction? Hypothesis: One of the main conditions that can affect enzyme activity is temperature. The rate of an enzyme-catalyzed reaction increases as the temperature is increased. A 10 degree Celsius rise in temperature will increase the activity of most enzymes by 50-100%. Somewhat, as small as 1-2 degrees Celsius may change to 10-20% in the results of fluctuation in reaction temperature.
The first factor that must be considered is the viscosity of the magma. This can determine how powerful an eruption is and what shape the volcano eventually becomes. Viscosity can be affected by three main factors, firstly, the higher the temperature, the lower the density of the magma, causing it to flow more easily. Secondly, the greater the amount of dissolved gases in the magma, the less viscous it will be, and lastly the higher the silica content, the more viscous it will be. Thicker, more viscous magma has a greater potential for explosive eruptions and therefore represent the greatest potential hazards.
Because the rate of reaction refers to how quickly the reactants are used up or how quickly the products are formed, one method is to measure the volume of gas given off, the more gas given off per time interval results faster reactions.Question: Will the changes in substrate concentration affect the rate of anaerobic reaction? Why or why not? What are the independent variable and dependent variable in this lab activity? What are some other controlled variables? Hypothesis: If substrate concentrations are changed, then as the concentration increase, the rate of anaerobic reaction will also increase, because the increase of the reactant concentration means there are more reactant particles, and there is a greater chance for these particles to collide and let reaction happen.
For this experiment, when the temperature increases, collision between the particles also increases. Hence, the rate of reaction increases with increasing concentration. It was also observed that the more crowded the molecules are, the more likely they are to collide and react with one another. In addition, temperature usually has a major effect on the rate of a chemical reaction. Molecules at higher temperature have more thermal energy.
Introduction The quantity of fission products in a nuclear reactor is dependent on the amount of fission occurring, which is directly related to fuel burnup. Therefore it follows that increased fuel burnup causes a rise in the quantity of fission products. Fission product behavior negatively impacts fuel performance in a number of different ways. The negative impacts on fuel performance that fission byproducts have include fuel swelling, pressure and stress on the cladding, as well as decreased thermal performance of the fuel; all of which limit the amount of burnup a reactor can undergo. The neutralization, reduction, or removal of fission products and subsequently their associated negative effects will allow for higher burnup in nuclear reactors.
