Lab 5 – Weather and Climate Change Lab 5 - Demonstration 1: Modeling the Water Cycle POST LAB QUESTIONS 1. Which water cycle processes are represented in this model and by what components? Answer = Condensation and evaporation are represented in this model. The warm water evaporated. Condensation formed inside the jar and under the lid of the jar.
3. How would the “weather” be affected if the water was at a decreased temperature? How would the “weather” be affected if the water temperature were increased? Answer = If the weather decreased in temperature, it would have less condensation on the lid because the temperature would have been less and the water would have no evaporated. Experiment 1: Water Movement POST LAB QUESTIONS 1.
5. Record the data in a chart with the times. Experiment Basically the experiment is on what household items can insulate and hold the circulation of cold air inside the ice box which allows freezing points or melting points to take course. Data/ Graphs Ice Boxes | Test 1(none) | Test 2 (salt) | Test 3(Sugar) | Cardboard | 7:14.8 | 12:52.7 | 8:35.2 | Paper | 9:28.4 | 12:14.8 | 7:43.6 | Aluminum Foil | 16:35.1 | 17:21.6 | 13:17.8 | Time Graph Observations When I experimented I noticed that one of the ice boxes melted quickly than the others, which could mean that those ice boxes vents heat. The substance added to the ice box could have either helped it stay cool or melted it quicker.
There is still carbon dioxide gas dissolved in the liquid at atmospheric pressure. The amount is very small and depends on temperature. It would be interesting to try this experiment again with a cold bottle and a warm bottle. Because carbon dioxide affects the pH of the soda it might be interesting to compare the pH of the fresh out of the bottle and the "defizzed" soda. What is the pressure that is used to put the carbon dioxide into the bottle in the first place?
The lack of red blood cells keeps the fish from freezing and the viscosity of the blood is also lower. This fish is designed to live in cold climates, if for any reason it were to get warmer the fish would not be able to live. It has no way for it to deal with the warmer environment and it has evolved specifically to obtain oxygen and retain heat in a cold environment, not a warm
If water was used as the solvent, it has a freezing point of 0 °C and the solution will freeze at even a lower temperature so you have to put it somewhere cool like a freezer. The freezing point depression concept can be used economically to make lots of money from applications such as antifreeze. Antifreeze is a liquid mixture composed of ethylene glycol and water and it’s vital for a car’s engine because it explains why car fuel doesn’t freeze in the winter and how combustion engines operate at freezing temperatures. The technology we depend in our daily lives like cars wouldn’t be able to function in the winter when it is too cold or even in the summer when it is too warm
2. What effects might this steady increase of carbon dioxide have on the organisms living in this area? -As stated before, photosynthesis performers would not be effected, as the can take in carbon dioxide. Respiratory breathers, however, face a fatal issue with extra carbon dioxide in the air. The population of respiratory breathers will slowly decrease, considering plants will give a little bit of oxygen.
Also, the excessive manure present in rainwater runoff during heavy storms cannot be called “agricultural stormwater discharges.” In C.A.R.E v Southview Farms, “The run-off was primarily caused by the over-saturation of the fields rather than the rain and that sufficient quantities of manure were present so that the run-off could not be classified as "stormwater. "” (1994). Therefore, Northfield Farms is in violation of the CWA for its disposal method of waste products as well as the manner in which waste floods surrounding private property.

The hydrologic cycle — also known as the water cycle — is the continuous exchange of water between Earth's surface and the atmosphere. As the planet's natural mechanism for transporting and recycling water, the hydrologic cycle is critical for maintaining conditions on Earth. There are five basic steps within the water cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration. Gaseous water vapor in the atmosphere condenses to form clouds, which can produce precipitation. Rain, snow, and sleet return water from the atmosphere to Earth's surface.
