oxygen-containing functional groups. A shift in the position of FFW peak was observed in MA during DSC analysis due to stronger hydrophilicity of microalgae compared with PS and PT samples. The freezing enthalpies of FFW in biomass samples were in the range of 319.04-297.7 kJ/kg and were in good agreement with the enthalpy of bulk water. Low-temperature XRD analysis was used to define the boundary between the FFW and NFW and indicated that more FFW was present in MA compared with PS and

for hundreds years and developed many applications those can catalogue into electricity generation and direct use. Australia is rich in geothermal resources. However‚ most of Australia’s geothermal resources are characterized by their medium-to-low enthalpy and are more suitable for direct uses. According to the research some recommendations are suggested. Recommendation1: Incorporate internationally that can develop geothermal technology faster. Recommendation2: Support research in geothermal resource

is often an energy that is deposited from the reaction. Decomposition Reactions: Decomposition reactions occur when one compound decomposes into two separate elements/compounds. The general equation of decomposition reactions is: AB→A+B. The following are the complete balanced equations for the two decomposition reactions performed in the lab. Reaction 6: Reaction 7: The decomposition of hydrogen peroxide is an example of decomposition. In the lab‚ this was tested when we added hydrogen peroxide

aboveground production and litter decomposition are thought to positively covary‚ because they are driven by shared biotic and climatic factors. Until now we have been unable to test whether production and decomposition are generally coupled across climatically dissimilar regions‚ because we lacked replicated data collected within a single vegetation type across multiple regions‚ obfuscating the drivers and generality of the association between production and decomposition. Furthermore‚ our understanding

In our ecocolumn many changes occurred over the several week course we were observing and collecting data on the three chambers. Aquatic and Decomposition quickly turned septic while terrestrial experienced plant growth. Overall the health of the ecosystem was very poor due to the severe changes in the aquatic chamber. Terrestrial In the Terrestrial camber of our ecocolumn‚ several changes happened over time. The clover seeds planted at the beginning had a rapid growth rate. At one point our chamber

heaviest metal was Metal B. The metal with the highest temperature was Metal B Calculations: Show your work and write a short explanation with each calculation. Part I: 1. Calculate the energy change (q) of the surroundings (water) using the enthalpy equation qwater = m × c × ΔT. We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. qwater = m × c × ΔT m = mass of water = density x volume = 1 x 26 = 26 grams

ENGINEERING THERMODYNAMICS FOR YEAR I ELECTRICAL 1 INTRODUCTION AND THE FIRST LAW OF THERMODYNAMICS All living things depend on energy for survival‚ and modern civilizations will continue to thrive only if existing sources of energy can be developed to meet the growing demands. Energy exists in many forms‚ from the energy locked in the atoms of matter itself to the intense radiant energy emitted by the sun. Many sources of energy exist: many are known‚ some perhaps unknown; but when
