Question:

Answers:Good question. Here is the process. Temperature differences create pressure differences. These pressure gradients cause winds. Winds cause the movement of air masses and help to create low pressure centers. Winds in the low pressure centers cause rising air which condenses the humidity in the air into water vapor (clouds) which releases heat of condensation which cause more temperature differences. All these processes work together in a very complicated (called non-linear) manner.

Question:How does change in temperature affect the rate of reaction? How does particle size or surface area affect the rate of reaction? How does a catalyst affect the rate of a chemical reaction?

Answers:As you increase the temperature the rate of reaction increases. As a rough approximation, for many reactions happening at around room temperature, the rate of reaction doubles for every 10 C rise in temperature. The more finely divided the solid is, the faster the reaction happens. A powdered solid will normally produce a faster reaction than if the same mass is present as a single lump. The powdered solid has a greater surface area than the single lump.

Question:Yeah, it's for geo. We already did that how much atmosphere there is, and the angle of the Sun, affects the temperature, but now our teacher is saying how does the sea affect temperature??? thanks x

Answers:The sea affects the temperature on land nearby :). How it affects it is called Continentality, and generally coastal areas will be cooler and wetter than inland areas, because of the different temperatures of the sand and sea making clouds condense and stuff :). This is the reason a lot of people in hot countries like Spain go on holidasy to the coast - to get a cooler holiday :).

Question:How are the temperature of the air and of the water near it (like a lake) related? higher? lower?

Answers:The old professor says: Heat energy will always flow from the higher level to the lower. Air does not have the heat capacity of water so it will be quicker to gain or lose it. Thus, the air/water will tend to equalize temperatures as the heat flows from the warm water to the air or warm air to the water. The air's influence over the water temp will be slower than the water's influence over the air.

Does Water Temperature Affect Fish? :This is a science demonstration to be used in a lab where students collect data from the video to complete the lab. Data is only available for 15 seconds, but the lab asks for a 60 second time period so data should be multipled by 4 for the purposes of this lab activity.
