What is the difference between infrared camera and thermal camera?
What is the difference between infrared camera and thermal camera? Active IR systems use short wavelength infrared light to illuminate an area of interest. Some of the infrared energy is reflected back to a camera and interpreted to generate an image. Thermal imaging systems use mid- or long wavelength IR energy. Can an infrared camera […]
How is a rainforest different from other forests?
How is a rainforest different from other forests? A rainforest is an ecosystem characterized by heavy rain and a dense tree canopy that lets very little light through to the understory.

The atmosphere shields Earth from the most harmful solar rays. How does atmosphere affect our daily life? Not only does it contain the oxygen we need […]
Which object will reach terminal velocity first?
Which object will reach terminal velocity first? A falling object will continue to accelerate to higher speeds until they encounter an amount of air resistance that is equal to their weight. Since the 150-kg skydiver weighs more (experiences a greater force of gravity), it will accelerate to higher speeds before reaching a terminal velocity. How […]

Is volume and temperature directly proportional?
Is volume and temperature directly proportional? The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law). Does pressure affect temperature? In a closed system where […]
