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‚ 2014)

A critical point happens when a substance has a high enough temperature and pressure that both liquid and gas can exist at the same time. This state is called a critical point. Now‚ when a state of matter changes from one state to another is called a phase shift. Phase shifts are extremely important and most commonly observe phase shifts daily. For an example‚ when water freezes into ice‚ or the water in the shower turns to steam. To begin to start describing how a phase shift works we must understand

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol

know that 250‚000 life organisms die a year because of the ocean temperatures rising? One reason the ocean temperature surges is because of the greenhouse gas. As greenhouse gas (a gas from the greenhouse effect that benefits by absorbing carbon dioxide‚ chlorofluorocarbons‚ and infrared radiation; different kinds of elements and gases) collects together and increases‚ it traps more heat energy into the Earth‚ and making the temperature rise. Another way this is caused is when the warmer ocean water

This 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

manual. The independent variable in this experiment was temperature as it was the effects of temperature that was being measured. The dependent variable were ventilation rates and oxygen consumption as they were being measured. There were 10 fish per treatment level. There were two treatment levels‚ 25 C and 15 C. Ten fish tanks per treatment level were set up‚ the first group of fish tank were filled with spring water and kept at room temperature of 25 C‚ whereas‚ the second group of fish tank were

The effect of temperature on the rate of maggot movement Research and Rationale This experiment is aiming to analyse the behaviour of maggots when they are exposed to light and the effect of that on their movement rate. Behaviour is the way in which animals respond to external factors is known as behaviour. As animals become bigger their behaviour becomes more complex. This is because larger animals tend to have a more complex nervous and hormonal system. Two of the types of behaviour are called

Temperature affects enzymes in two different ways: by increasing the kinetic motion of molecules‚ changing the rate of collisions between them and the hydrogen bonds it’s 3D structure(D. Fraser‚ 55). There is a specific temperature for every enzyme where activity is maximized‚ and also where an enzyme becomes denatured. An enzyme becomes denatured when it is heated at extreme temperature; the excessive kinetic movement of the amino acid begins

be seen in the graph‚ the higher the temperature the shorter the time is for the Sulphur to be created. If it is looked as one continuous line‚ the first part of the trend line shows a steep‚ straight and constant decrease; then the 2nd part is not as steep and has a more gradual decline. Moreover‚ it shows how a reaction at 20°C a slower time for the cross to disappear compared to 40°C and especially 60°C. Both graphs show how temperature has a great effect on the speed of sulfur formation covering

decreased‚ particles are closer together‚ so they don’t move as much because they are low in energy as well as space. Temperature: The question being asked to answer is if temperature is affected by thermal energy. My answer to that question is its affected because when you add thermal energy the temperature increases and it becomes warmer‚ but when thermal energy is decreased the temperature becomes frigid. State of Pure Substance: Is the state of pure substance is affected by thermal energy? My answer
