magnet affect by warm or cold temperatures? This experiment showed that if a magnet is cold‚ then it will have more magnetic pull than a warm magnet. The independent variable is the temperature of magnets. The dependent variable is the magnetic pull of magnets. The experimental group is magnets exposed to different temperatures. The control group is the room temperature magnet. The control variables are the amount of time the magnets are exposed to different temperatures‚ the type of magnet‚ and the

Investigate temperature change during a neutralization reaction Introduction: When an alkali neutralizes an acid‚ a salt and water are formed. Aqueous hydrogen ions (H+(aq)) from the acid react with the hydroxide ions (OH-(aq)) from the alkali‚ forming water. For hydrochloric acid and sodium hydroxide: H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) → Na+(aq) + Cl-(aq) + H2O(l) Hydrochloric acid Hydrochloric acid Sodium Chloride Sodium Chloride Sodium Hydroxide Sodium Hydroxide Neutralization

Title of Experiment: The Effect of Temperature on the Hatching Success of Brine Shrimps. Abstract In this experiment‚ 40 brine shrimp eggs are put into a test tube containing salt water at different temperature such as 25°C and 35°C respectively. The eggs are left from two days to hatch. After two days‚ the number of eggs successfully hatched are observed and counted. Introduction Brine shrimp is the common name for a primordial crustacean that reaches less than 1.3 cm in length and is usually

Optimal Temperature and PH of Barley Amylase Abstract The purpose of this experiment was to find the optimal temperature and pH of barley alpha-amylase. I hypothesize that the optimal temperature would be 55 degrees Celsius and the optimal pH would be 5.5. In this experiment‚ the starch is used as a substrate to examine the optimum temperature and pH for the reaction of alpha amylase. It is known that the measuring of disappearance (absorbance) of the substrate starch with iodine using spectrophotometer

Analyze the reasons why costs need to be controlled to budget. The important responsibilities are to be able to control budgets and costs and also make sure that they are making a positive financial input to the business. Business has costs in which different varieties of finance are used to cover different types of business costs. You should control costs if you want to earn more money‚ since the whole world is in recession now if you control costs now you can be in secure place. If still

Purpose: This laboratory was performed to find the temperature change‚ heat of reaction‚ and enthalpy change for neutralization reactions. The temperature change was found by subtracting the initial temperature from the final temperature obtained. Heat of reaction is negative heat of solution. Heat of solution was found by using the formula qsolution = mCsΔT (m= mass; Cs= 4.184 J/g°C; and ΔT = change in temperature). The enthalpy change was found by dividing the heat of reaction by the number of

experiment was designed to study the effect of exercise on skin temperature and heart rate. Studying the effect of exercise on skin temperature and heart rate yields understanding of how homeostasis is achieved in humans. This knowledge creates opportunity to discover more effective ways to return the human body to optimal functioning‚ rather than a reliance on natural processes. This experiment measured the change in skin temperature and heart rate of a chosen subject for four two-minute intervals
