It's more powerful than a central air conditioner.At the same time, researchers in Saudi Arabi a are developing a cooling system that can work without electricity. It uses the energy from sunlight to cool down. The system uses a natural phenomenon(现象) that happens when salt is added to ...
It can make your hair frizzy and may seem to dampen everything, including your mood. When people complain about humidity, for the most part they're talking about relative humidity. Depending on temperature, air can hold a fixed amount of water vapor; relative humidity is the ratio of actual...
When the air gets close to the shore, it's slowed down by the land, and starts to pile up. So it rises even faster, because it has nowhere else to go. That's where topography comes into the picture.MALE STUDENT: And then it snows because as the air rises, it cools off and ...
The avenue is also the perfect place to observe different types of cyclists. Those such as Qian always attempt to improve their time, so it’s easy to sense their frustration when they have to stop at red lights.Others prefer to ride at a slower pace, never missing the opportunity to tak...
Big pieces of rock may be thrown high into the air. After a while the volcano becomes quiet again. The melted lava becomes hard. Later the same thing happens again and again. Each time more hot lava pours out on top of the cold lava and then becomes hard. In this way a kind of ...
it leaves a lower pressure region below it. This process repeats as air from higher pressure areas moves into the lower pressure area, heats up, and rises, in turn, producing swirls in the air,according to NASA. Once this hot air gets high enough into the atmosphere, it cools off and ...
To scientists, an ice-free day does not mean there is absolutely no ice in the water. Instead, the term is measured by the quantity of ice in the water below a certain threshold. According to researchers, the ocean is ice-free when it has less than 1 million square kilometers, or 386...
The first thing to know here is that the velocity of the air matters. When the air moves quickly through the coil, it cools down to a certain point. If you now slow that air down so that each little bit of it spends more time in contact with the coil, it gets cooler. And that ...
The heat is released into the outside air as it passes through the radiator. This cools the coolant to recirculate through the engine and absorb more heat.When coolant levels get too low, its heat-absorbing properties decrease. This allows engine temperatures to climb unchecked. Prolonged ...
