changes in temperature expands the air inside of the basketball causing it to bounce higher. This experiment was decided by observations made while playing the sport basketball. It was observed that when a basketball is left in the sun and made warm‚ the ball bounces higher when dribbled than if left inside. Our assumed result was that an increase in temperature would cause an increase in air pressure causing the bounce of the basketball to increase. The independent variable was the temperature in which

Copper Chloride Lab Report Procedure Part A: 1. Pick up the container of copper chloride dehydrate‚ and observe material. Describe crystals in detail‚ and write down all of the observations. Part B: 1. Take a 100 ml beaker and fill ¼ of it with water. Use a spatula to add some copper chloride dehydrate to the beaker filled with water. Record the observations. Be sure to observe the water and the copper chloride dehydrate. 2. Stir the contents in the beaker with

atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC‚ and the air temperature is 20 oC. The overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and what distance will be required for the steam to reach a mean temperature of 100 oC? Question 2: Consider a horizontal‚ thin walled circular tube

Transpiration and Leaf Resistance By: Bernina Berber Introduction Transpiration is a part of the water cycle process‚ and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants)‚ especially in leaves but also in stems‚ flowers and roots. Stomata are dots with openings on

Copper Sulphate Calibration Aim The objective of this experiment is to determine the unknown concentrations of solutions. Introduction With the use of absorption of light a spectrophotometer sends UV wavelengths through solutions to determine their concentrations. The light absorbed is measured as the atoms‚ molecules and ions absorb the wavelengths of light that the spectrophotometer gives off (Meah‚2013). The level of light transmitted defines the amount of light absorbed‚ for instance‚ the lower

of Part A in this experiment‚ it can be determined that Sodium Chloride had the highest amount of conductivity tested by all groups. On the graph above‚ the data shows that NaCl (sodium chloride) held the highest amount of electrical conductivity for all groups and on the table it reads the highest numbers across its row. Also as seen in the data above‚ ethanol had the lowest amount of conductivity with sucrose‚ acetic acid‚ ammonia‚ and MgCl2 following in ascending order. It can also be determined
