1. Heat Transfer Mechanisms

What are the four mechanisms of heat/energy transfer? Give an example for each. What happens to energy when water evaporates – gained or lost? What happens to energy when water condenses –gained or lost? Explain how thermohaline circulation of ocean water affects global temperature distribution. Must be 350 words long.

give a good explanation and examples of each. this is physical geography. they have to be long explanation.

Workers in the most chemical process industries are exposed to various
toxic chemicals without considering health and safety measures that could
lead to different harmful symptoms. If you will be given a task to work as a
chemical engineer, for health and safety in the process industries, what
necessary measures and risk assessment techniques would you
implement in order to control and reduce the level of risk?

Consider some of the disaster events we have experienced or that you have seen in the news during the past few years, occurring locally, across a state, nationally, or globally. What event do you think is most likely to be the next "big" disaster? Tell why you chose this event, and what you think the Public Health Response system's role should be in responding to it.
