“Temperature, Heat, and Pressure”

Choose one of the following topics for your initial post this week. Make sure that your initial post and all replies are related to the discussion topic you chose and to the weekly course material. How is heat and temperature related to the weekly course material? For example, how does the weekly reading relate to the discussion topic that you chose?

• Watch the video titled “Heat and Temperature Introduction” (2 min 30 sec) under the Temperature and Heat terms section of the Science Corner. You can also view the video at https://www.youtube.com/watch?v=v1zOnyC4RgQD. Next, describe the fundamental differences and similarities between temperature and heat. Then, analyze how heat transfer occurs during the processes of conduction and convection. Provide one (1) example of where each occurs in natural physical systems.
• Watch the video titled “USGS Gas Hydrates Lab” (6 min 44 sec) under the Gas Hydrate terms section of the Science Corner. You can also view the video at #t=12. Next, explain the main reasons why pressure and temperature play a critical role in the stability of gas hydrates. Identify at least two (2) situations where methane hydrate deposits predominantly occur and discuss the key challenge(s) in locating and harvesting methane hydrate under each situation.
• Suppose it is a very hot summer day and you want to cool your kitchen. Unfortunately the windows and doors in your kitchen cannot be opened. You have either a fan or a refrigerator to cool the kitchen. Which do you believe would be more effective to cool the room? Explain your answer then try testing your theory.
