Is energy balance a simple concept?
Is energy balance a simple concept? The concept of energy balance seems simple on paper. Balance the calories you consume with the calories you expend. But many factors play a role in energy intake and energy expenditure. What is energy balance model? Energy balance models (EBM) are simple climate models that try to predict the […]
What is the difference between Thhn and THWN wire?
What is the difference between Thhn and THWN wire? THHN is a code for thermoplastic high heat resistant nylon coated wire which is allowed for use in dry to damp location and rated for a maximum temperature of 90ºC (194ºF). The THWN wire we carry is actually coded THWN-2 indicating its rated 90 degrees for […]
What characteristics are used to describe air masses?
What characteristics are used to describe air masses? Temperature and humidity are two characteristics used to classify air masses. Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). What are the five major types of air masses? These are Polar (cold), Arctic (very cold), Equatorial (warm and […]
Which of the following best describes how the greenhouse effect works?
Which of the following best describes how the greenhouse effect works? Which of the following best describes how the greenhouse effect works? A planet’s surface absorbs visible sunlight and returns this absorbed energy to space as infrared light. Greenhouse gases slow the escape of this infrared radiation, which thereby heats the lower atmosphere. Which of […]

Why does low pH increase solubility?
Why does low pH increase solubility? The anion in many sparingly soluble salts is the conjugate base of a weak acid. At low pH, protonation of the anion can dramatically increase the solubility of the salt. Basic oxides either react with water to give a basic solution or dissolve in strong acid; most basic oxides […]

What is caused by differences in ocean water density?
What is caused by differences in ocean water density? The colder and saltier the ocean water, the denser it is. The greater the density differences between different layers in the water column, the greater the mixing and circulation. Density differences in ocean water contribute to a global-scale circulation system, also called the global conveyor belt. […]
