What is the relationship between atmospheric pressure and altitude? Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than […]
What are 4 things we automatically process?
What are 4 things we automatically process? Some examples of automatic processes include motor skills, implicit biases, procedural tasks, and priming. The tasks that are listed can be done without the need for conscious attention. Implicit biases are snap judgments that people make without being aware that they made them. What three things do we […]
What are the five assumptions of an ideal gas?
What are the five assumptions of an ideal gas? The ideal gas law assumes that gases behave ideally, meaning they adhere to the following characteristics: (1) the collisions occurring between molecules are elastic and their motion is frictionless, meaning that the molecules do not lose energy; (2) the total volume of the individual molecules is […]
How do we digest starch?
How do we digest starch? Starch breaks down to shorter glucose chains. This process starts in the mouth with salivary amylase. The process slows in the stomach and then goes into overdrive in the small intestines. The short glucose chains are broken down to maltose and then to glucose. Which organ is primarily responsible for […]
What is diagram example?
What is diagram example? In science the term is used in both ways. For example, Anderson (1997) stated more generally: “diagrams are pictorial, yet abstract, representations of information, and maps, line graphs, bar charts, engineering blueprints, and architects’ sketches are all examples of diagrams, whereas photographs and video are not”. Why is a diagram important? […]
Which waves can carry information?
Which waves can carry information? While many different types of EMF are used to convey information over distance, the most common are radio waves, also called radiofrequencies. This is a wide spectrum ranging from tens of kilohertz to 300 gigahertz. Within this spectrum, frequency bands are allocated to each use. How do we use waves? […]

Why heating an air parcel causes it to rise?
Why heating an air parcel causes it to rise? Warm air rises primarily due its lower density as compared to cooler air. As the temperature increases, the density of the air decreases. As the denser air reaches the earth’s surface it spreads and undercuts the less dense air which, in turn, forces the less dense […]
What solutions are there to global warming?
What solutions are there to global warming? For example, improvements to energy efficiency and vehicle fuel economy, increases in wind and solar power, biofuels from organic waste, setting a price on carbon, and protecting forests are all potent ways to reduce the amount of carbon dioxide and other gases trapping heat on the planet. Are […]
Where is the potential energy of the system the greatest?
Where is the potential energy of the system the greatest? Where is the potential energy of the system the greatest? At the highest point of the oscillation. At the new equilibrium position of the oscillation. Is potential energy negative or positive? This is a negative value for two reasons; the force acting between them is […]
