Evaporation and Transpiration Evaporation and transpiration (evapotranspiration) are components of hydrologic cycle‚ which at principle‚ can be calculated from meteorological observations such as temperature‚ humidity‚ radiation‚ wind speed‚ etc. The process‚ however‚ is quite complex and a substantial literature has been produced on it. In this chapter our focus is mainly on the concept and simple estimations of evaporation and transpiration. Mechanism of evaporation from water surfaces Here

The height difference that is used in the experiment varies from 0.5m. It adds by 0.5m in every drop height. A trend line showed on the graph and explains that the higher the drop height the higher the ball bounces back. When the height the ball bounces back is rounded the pattern of increasing the bounce height is by 0.2 m as shown‚ 0.7‚ 0.9‚ 1.0. The pattern of the bounce height explains this when the numbers are rounded. In each increasing drop height‚ the amount of m that the ball has bounced

Adriana Rempson Mrs. Steeger AP Biology-7 10 October 2012 Transpiration in Plants Abstract: Our group wanted to see how transpiration would happen in plants when they were in different environments. The different environments we used were humidity and room environments. We measured transpiration using the whole plant method. Our results showed that the plants in a humid environment had greater transpiration rates than the plants in the room environment. Introduction: Pants absorb and

Variables: Independent variables: temperature of water where the elodea(plant) is going to be placed Dependent variable: the amount of oxygen produced by photosynthesis reaction Control variables: Light concentration entering the beaker Length of the plant Volume of the water to be precise And of the NaHCO3 What is the variable to be controlled. Why does it need to be controlled. How will you

experiment was to determine the effect of temperature on the rate of movement of Porcellio scaber. Our prediction was that P. scaber would have faster rates of movement in hotter temperatures. We expected this response as P. scaber is an ectotherm. Hence‚ its body temperature is directly determined by the temperature of its environment (Mellanby 1939). Løkke and van Gestel (1998) stated that the rate of the metabolism is controlled by the environmental temperature for ectotherms. As seen by Wieser‚ cited

To begin the analysis‚ the properties of the air at the base of the tower were examined. The wet and dry bulb temperatures of the air at the inlet were used to find the humidity‚ humid volume‚ and enthalpy of dry air. For example‚ in the first trial the dry bulb temperature was 22.5⁰C and the wet bulb was 16.5⁰C‚ and the properties found from the psychrometric chart are listed below. H_bottom=0.0095 kg/(kg dry air) V_bottom=0.85 m^3/(kg dry air) h_bottom=47 kg/(kg dry air) Then‚ the cross-sectional

meter (N/m2)‚ or pascals (Pa). 3. Slowly drag the temperature (T) slider back and forth. (Note: In this Gizmo‚ the Kelvin scale is used to measure temperature. On the Kelvin scale‚ 0 degrees is absolute zero‚ the coldest possible temperature. Absolute zero is equal to -273.15 °C or -459.67 °F) A. How does the change in temperature affect the speed of the molecules? __If the temperature is colder the molecules move slower and if the temperature is hotter the molecules move faster.
