Affecting the environment Describe natural factors that have changed the surface and atmosphere of the Earth. Natural factors such as volcanic eruptions‚ changes in the Earth orbit and the amount of energy released from the Sun which can affect the Earth climate. Also human activities can be another reason why atmosphere is of the Earth is changing. When we burn fossil fuel such as coal‚ oil‚ and deforestation have caused the concentrations of heat-trapping “Greenhouse Gas” will increases significantly

RECENT DEVELOPMENTS IN NANOPARTICLES. INTRODUCTION Nanotechnology is a multidisciplinary scientific field undergoing explosive development. Nanometer-sized particles offer novel structural‚ optical and electronic properties that are not attainable with individual molecules or bulk solids. Advances in nanomedicine can be made by engineering nanoparticles that are capable of targeted delivery of drugs. This leads toward the concept and possibility of personalized medicine for the potential

uk/schools/gcsebitesize/science/ocr_gateway/home_energy/heating_housesrev3.shtml The specific latent heat of a substance is a measure of how much heat energy is needed to melt or boil it. It is the energy needed to melt or boil 1 kg of the substance. Different substances have different specific latent heats. The specific latent heat of a given substance is different for boiling than it is for melting. The table shows some examples. Latent heats of substances substance specific latent heat of melting

regarded as one of the most important scientists in classical antiquity. In addition to making important discoveries in the field of mathematics and geometry‚ he is credited with producing machines that were well ahead of their time. The Ancient Roman historians showed a strong interest in Archimedes and wrote several biographies relating to his life and works‚ while the few copies of his treatises that survived through the Middle Ages were a major influence on scientists during the Renaissance.

1) Why does the Earth have seasons? Describe the relationship of the Earth and Sun in each of our four seasons. Contrary to what most people believe‚ seasons on Earth are not caused by the distance of our planet in relation to the Sun. This is a common misconception due to the Earth’s elliptical orbit around the Sun‚ which means there are times that the Earth is closer to the Sun‚ and times when it is farther away. If the Earth’s proximity to the Sun was the cause of our seasons‚ then they would

For my Chemistry paper I decided that I would do technology. Some of the topics I chose for my paper was how chemistry helps with technology by helping with Forsenic Science‚ Crime Scene Investigations‚ the wiring of bombs‚ fireworks and guns preventing premature detonatations‚ and Engineering. Chemistry deals with technology and sciences since technology is used to make experiments. Another example of everyday use is the computer that helps you in your research and communications. Forensic
