What behavior affects the combustion of thermoplastics like polypropylene, nylon, or polystyrene?
Homework Answers
The melt flow behaviour of thermoplastics like polypropylene nylon or polystyrene does effect the combustion of thermoplastics. Thermodynamics melt flow behaviour effects the dynamics of fire growth.
The ease of flow of molten thermoplastic polymer is called melt flow index of the polymer. It is measured as weight of polymers flowing in 10 minutes through a die of specific diameter and length by an applied pressure of some weight at a certain temperature.
Thermoplastics of high melt flow behaviour do not catch fire rapidly. That is because the past that has caught fire rapidly melts and leave the solid thermoplastic as the ease of flow is very high. So high melt flow index of thermoplastic slows down the dynamics of combustion growth and prevents thermoplastic from fire.

A researcher would like to determine whether humidity can have an effect on eating behavior. It’s known that under regular circumstances laboratory rats eat an average of μ=10 grams of food each day, with standard deviation σ=2. The researcher selects a random sample of n=16 rats and places them in a controlled atmosphere room where the relative humidity is maintained at 90%. For these rats in humid atmosphere, the average daily food consumption is 13 grams. The researcher tests at...

Post a description of one behavior that you would like to change in your professional life—one that significantly impacts how you manage or relate to others—and briefly describe this behavior in your post. Then think about your goals and consider three questions: What should I stop doing? What could I start doing? What might I want to do differently? Finally, consider the benefits, implications, or consequences to stopping, starting, or changing the behaviors you thought about.

10. What is true with respect to thermoregulation? a. Endotherms do not use behavior to control heat exchange with the environment b.Thermoregulation is important because temperature affects movement of chemical substances across the membranes of cells c.In mammals, the sinoatrial node serves as the physiological sensor/control center for body temperature d. Ectotherms do not produce any heat in metabolic reactions

Choose a behavior of yours that you would like to try to modify using the principles of behaviorism. Keep it simple and clearly measurable (for example, not "I should exercise more," but "I want to jog one mile a day" – not, "I don't want to be so shy," but "I want to talk to one new person each day" – not, "I want better grades," but "I want to study X amount each day"). Days 1-3: For three days, merely...
