Does Temperature of Kernels Affect Popcorn Yield?

Does Temperature of Kernels Affect Popcorn Yield? Project Design Plan This experiment will attempt to determine if the temperature that popcorn kernels are stored at will affect the amount of un-popped kernels when using a hot air popcorn popper. Popcorn kernels contain moisture inside of them which, when heated, turns to steam and expands that in turn causes the kernel to explode. Popcorn.org states that loss of moisture content can cause less yield amounts when popping popcorn (popcorn.org...

The Effect of Temperature on the Rate of an Enzyme Catalysed Reaction

Aim: To find the effect of temperature on enzymes, using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances, composed of polymers of amino acids, that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories, such as hydrolytic, oxidising, and reducing, depending...

Compare responses of named Australian ectothermic and endothermic organisms to changes in the ambient temperature and explain how these responses assist in temperature regulation

are organisms that have a limited ability to control their body temperature. Their cellular activities generate little heat. Their body temperatures rise and fall with ambient temperature changes. Most organisms are ectotherms. Examples are plants, all invertebrates, fish, amphibians and reptiles - ENDOTHERMS are organisms whose metabolism generates enough heat to maintain an internal temperature independent of the ambient temperature. Examples are birds and mammals - EXTENSION (Not really needed...

Effect of Temperature on Enzyme Catalase Activity in a Potato

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10, 37, 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start...

High Temperature Insulation Market - Global Trends & Forecasts (2011 - 2016)

High Temperature Insulation Market - HTI Application and Temperature Range - Global Trends & Forecasts (2011 - 2016) On 1st May 2012 The increasing cost of power and the rapid depletion of conventional sources of energy have necessitated effective heat management and energy conservation in industrial processes. High temperature insulation (HTI) products provide high compressive strength and low shrinkage at high temperatures; and thus offer a cost-effective energy management solution for industrial...

How Does Temperature Affect the Ability to Bounce of a Ping-Pong Ball?

How Does Temperature affect the Ability to Bounce of a Ping-Pong ball? Physics Design Practical Research Question How is the bounce-height of a ping pong ball affected by it’s temperature? This research questions aims to find out how the temperature of a ping pong ball affects the vertical height bounce, after being dropped from 1 metre. I will be measuring the bounce height using a video camera to find the heightest point. I will use the top of the ball for ease of results. Hypothesis:...

A lab report on the investigation of temperature on catalase activity.

INVESTIGATION INTO THE EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase's different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a...

Investigation of the effect of the mass of Zinc, on the temperature change of a Copper Sulphate solution

diagram above.) 2.Secondly I will measure the required amount of Zinc (Zn) on a weighing scale, again for precise accuracy. I will then measure the starting temperature using a thermometer. Next I will pour the Zinc into the test tube containing CuSO4. 3.Finally I will measure the final temperature using a thermometer and record the temperature rise in °c. (I will carry out all my experiments under lab safety precautions.) Variables *I will vary the mass of Zinc, & use the following Zinc weights:...
