What is the impact of human activity on the natural environment? Answer: Humans are a part of the natural environment. Unfortunately‚ we have not yet learnt to moderate our activities in such a way as to help the environment. Human activities often lead to degradation of the environment. Impacts of humans include: • pollution - land‚ freshwater creeks and rivers‚ seas and oceans‚ and air • deforestation and destruction of habitats • endangerment and extinction of flora and fauna species

Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula

Conduction Conduction Conduction is the transfer of thermal energy between regions of matter due to a temperature gradient. In the engineering sciences‚ heat transfer includes the processes of thermal radiation‚ convection‚ and sometimes mass transfer and often more than one of these processes occurs in a given situation.Shaun Prado 8F Shaun Prado 8F Steady-state conduction Steady state conduction is the form of conduction.

Topic: Ghost Hunting Equipment Specific Purpose: To inform the interviewing jury the proper equipment used for a successful ghost hunt. Introduction: I. Attention Material: Ghost hunting is filled with different types of emotions. Scary‚ sad‚ excited‚ nervous‚ angry‚ etc. are all different emotions you could feel during a ghost hunt. All in all though it is a fun time and cool to experience with your friends. It is also very interesting to hear the history of a specific area and have

heating by solar radiation were the only warming mechanism. Solar radiation at the high frequencies of visible light passes through the atmosphere to warm the planetary surface‚ which then emits this energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases‚ which in turn re-radiate much of the energy to the surface and lower atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse but

increased levels of carbon dioxide‚ CFCs‚ and other pollutants. The greenhouse effect is the trapping of the sun ’s warmth in a planet ’s lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet ’s surface. In simpler terms‚ this means that the pollution emitted from the earth‚ such as the gasses from factories‚ cars etc. enter the atmosphere and the co2 from these gases absorb the heat from the sun and
