(Kelvin (K) is a unit of temperature like Celsius and Fahrenheit). You can heat or cool the substances in the container by sliding the bar on the bucket to Heat (for fire) or Cool (for ice). Slide the bar to Cool and cool the neon to 0 K (this will take a while). a) The atoms are not in motion

1. The red color on the map indicates relatively high Sea Surface Temperature‚ a range from 27 degrees Celsius to 28 degrees Celsius‚ and also indicates the presence of warm currents. The temperatures show that that oceanic area is prone to hurricanes. The average temperature seems to be about 25.4 degrees Celsius because it is the middle of the range for the color gradient given with the map. 2. As the color turns from blue to white to red to yellow‚ as the wavelength gets longer‚ the SST increases

Discussion: Extraction and crystallization- The purpose of this lab was to extract and crystallize compounds in a mixture using acids and bases. 1 gram of the unknown was dissolved into 30 mL of ethyl acetate. The mixture was then transferred to a separatory funnel. Using aqueous solutions of different pH we were able to separate organic acids‚ bases and neutral compounds from each other. Using three 10 mL portions of HCl‚ we reacted the HCl with the base in solution. This made it possible to

begin this test‚ 3 water baths were set up. One bath was cooled to 0 degrees celsius‚ one was heated to 37 degrees celsius‚ and one was boiled to 100 degrees celsius. 1 of the four test tubes containing 2 ml of 100 units/ml catalase was put in to each of the three water baths‚ one at a time. While the tubes sat in the baths‚ the 4 H2O2 vials were prepared and the depth of the H2O2 was recorded. After the 0 degree celsius test tube incubated in it’s bath‚ it was taken out and a filter was dropped into

In a previous experiment‚ food was heated up to experimental temperature and fed to lizards. The lizards were then placed in a metabolic chamber‚ and measurements were taken for elevated metabolism at 35 degrees Celsius. An hour later‚ measurements were taken again at 24-26 degrees Celsius. Minimal endothermy was determined in both experiments (Bennett 2000). The three sub factors of solar energy absorption include convection‚ conduction‚ and radiation. Convection is a continuous circulation of liquid

is around 25 degrees Celsius. The dependent variable is the length of time the glow sticks will glow. This is determined by using my stopwatch to measure the time and a thermometer that checks the heat level. 2. Measure out the same amount of water into all three cups. Label the cups: Hot‚ Cold‚ Room temp. 3. The cold water cup should be at 5-15 degrees Celsius. The hot cup should be around 35-45 degrees Celsius. The room temperature cup should be around 25 degrees Celsius. 4. Pour hot water into

Abstract: The rate of photosynthesis and cellular respiration can change in varying conditions. How does the rate change with varying degrees of temperature and light exposure? To test this algae beads were exposed to a CO2 indicator‚ which changes colors based on the level CO2 level present. The algae beads were exposed to two different variables‚ light and temperature and tested for color change‚ Ph‚ level‚ and CO2 absorbance level. The beads were exposed to a light and a dark condition‚ and another
