Internal Assesment - Task 2C In this experiment I am investigating the relationship between surface area and the volume of a model cactus and to determine whether this relationship affects the loss of water. We used oasis blocks‚ an absorbant material used by florists as a substitute for a cactus‚ that would soak up the water‚ and thus ideally show the percentage water loss by weighing the before and after evaporation weights. Independent Variable The independent variable is the total surface

3. The various packaging methods of granulated sugar that is distributed in supermarkets is important to consider because of environmental factors‚ cost-efficiency and customer satisfaction. The consumer is paying for a product and it is the producer’s job to ensure the packaging is effective as well as protective. Two types of granulated sugar packaging methods I will analyze are paper-based packages and re-sealable plastic zipper bags. Paper bags are most commonly used in supermarkets due

to the center. At the top of Jupiter’s clouds the temperature is around -230 degrees Fahrenheit or -145 degrees Celsius. Jupiter’s temperature increases as you descend closer to the center of the planet. The temperature can increase so much to the point where atmospheric pressure is ten times greater than that on Earth and the temperature is 21 degrees Celsius which scientists call “room temperature.” This part of Jupiter is believed to possibly be able to support life‚ which would have to float and

Maricela Sandoval Period 2 10/27/12 Title of Lab: The Melting Temperature of a Pure Substance Purpose: The goal of this experiment was to find the melting point of Paradichlorobenzene and to observe the freezing/melting of a substance. The purpose was to also observe an endothermic and exothermic process. Introduction: The uses of Paradichlorobenzene are mainly as a fumigant for the control of moths‚ molds‚ and mildews‚ and as a space deodorant for toilets and refuse containers. It is also

The simulation and analysis of liquid droplets with respect to heat capacity and droplet size Abstract Define Using Molecular dynamic simulation a cluster of particles was modelled and their behaviour analysed with respect to temperature change. As proof of a specific state i.e. solid‚ the Mean squared displacement was calculated and illustrated with respect to time. This occurred for varying temperatures. From the internal energy of the system per time step‚ the heat capacity was determined

subtract the temperature of the psychrometer from the starting temperature and that is the difference. Then you must look at the humidity in the black text book to determine the relative humidity. A psychrometer is an instrument designed to measure dew point and relative humidity. 3. Evaporation is a cooling process because heat is taken out of water when the process occurs. Energy is used to break the bonds that hold water molecules together‚ which is why‚ water easily evaporates. The humidity level

Introduction The purpose of this experiment is to determine the effect that temperature has on the growth and respiration of yeast fermentation. The growth and respiration of the yeast can be determined by using a glucose/ yeast solution mixed with water in flasks set at different temperatures. Yeast in order to produce‚ has to make energy‚ to carry out all cellular functions (Spicer‚ & Holbrook‚ 2007). The concept that aerobic metabolism of all yeasts‚ is determined by the relative sizes of the
