Why is the ground under my house wet?
Why is the ground under my house wet? Most times, water in the crawl space gets there one of three ways: a plumbing leak, water seepage from the surrounding soil (usually after heavy rain), or condensation. Humidity condenses on cold surfaces, like ducts, and drips onto the crawl space floor. How long does it take […]
Can you get struck by lightning in the bathtub?
Can you get struck by lightning in the bathtub? Most people hit by lightning are outside. But, according to Snopes.com, lightning striking into the ground near homes has sent electricity up pipes and into sinks and bathtubs.

How many plates are on Mars?
How many plates are on Mars? two plates Is Olympus Mons still growing? Scientists posit that Olympus Mons is still a fairly young volcano from a geologic standpoint, estimating it to be only a few million years old. That being said, there’s a good chance that it’s still active and could erupt at some point […]
What is the importance of metastable state?
What is the importance of metastable state? In a three-level laser, the material is first excited to a short-lived high-energy state that spontaneously drops to a somewhat lower-energy state with an unusually long lifetime, called a metastable state. The metastable state is important because it traps and holds the excitation energy, building up a… What […]

Which is the best example of heat being transferred mainly by radiation?
Which is the best example of heat being transferred mainly by radiation? Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun. A less obvious example is thermal radiation from the human […]
