What do Li C and F have in common? The elements Li, C, and F, are all in the period (row) # 2 of the periodic table, and, in consequence, those atoms have two energy levels (main quantum number), n = 1 and n = 2, around the nucleus. Is Potassium a main group element? […]
What is food temperature control?
What is food temperature control? Using temperature controls minimizes the potential for harmful bacterial growth and toxin formation in TCS food. Temperature controls either keep food entirely out of the danger zone or pass food through the danger zone as quickly as possible. What is considered a low oven temperature? Oven Temperature Conversions Cooking Instructions […]
How many and of what types of variables will an experimental study have quizlet?
How many and of what types of variables will an experimental study have quizlet? An experiment has two independent variables. One has two levels and the other has three levels. Why is a hypothesis considered a model quizlet? A hypothesis is a testable model aimed at describing a phenomenon that can be tested or proved. […]
What is heating by convection?
What is heating by convection? Heat convection is a mode of heat transfer by the mass motion of a fluid such as air. Heat convection occurs to the surface of an object where the surrounding fluid of object is heated and moved energy away from the source of heat. What are the similarities of conduction […]
For what reason would a theory be changed or replaced?
For what reason would a theory be changed or replaced? A useful theory that has been tested and supported may become a dominant view among the majority of scientists. However, science is always changing. As new evidence is uncovered, a theory may be revised or replaced by a more useful explanation. Can a theory be […]
Is friction a form of mechanical energy?
Is friction a form of mechanical energy? The mechanical energy of the system remains constant provided there is no loss of energy due to friction. The energy would transform to kinetic energy when the speed is increasing. The mechanical energy of the system increases provided there is no loss of energy due to friction. Is […]
Which metal oxides is easiest to decompose on heating?
Which metal oxides is easiest to decompose on heating? The simplest kind of decomposition reaction is when a binary compound decomposes into its elements. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. Mercury(II) oxide is a red solid. When it is heated, it decomposes into mercury metal and oxygen […]
What is the reaction force that propels a rocket forward?
What is the reaction force that propels a rocket forward? As these gases are pushed out in one direction, there is a reaction force that pushes the rocket in the other direction. This reaction force is called thrust. What is the difference between space shuttles and other rockets? The space shuttle launched like a rocket. […]
What is a weakness of repeated measures?
What is a weakness of repeated measures? Repeated measures designs have some disadvantages compared to designs that have independent groups. The biggest drawbacks are known as order effects, and they are caused by exposing the subjects to multiple treatments. Order effects are related to the order that treatments are given but not due to the […]
What does light mean?
What does light mean? Light is one of the most universal and fundamental symbols. It is the spiritual and the divine, it is illumination and intelligence. Light is the source of goodness and the ultimate reality, and it accompanies transcendence into the Nirvana of Buddhist doctrine. What does light mean in life? It may mean […]
