What has sex got to do with electricity, you might wonder? Well, sex does funny things to us. When we feel aroused, all our nerve endings tingle, the hair on the back of our neck stands up, some people even get goose bumps. Our heart beats faster, our body temperature suddenly shoots...
You may reduce the temperature manually for a few hours, but remember to readjust afterwards. Excessively frigid temperatures can raise electricity bills and dry up food, reducing its flavor. Accumulated ice indicates an excessively chilly freezer temperature. For instance, Haier'sChest Freezer 200L ...
Doctors say heatstroke is a serious heat-related emergency that occurs when the body is unable to control its internal temperature due to exposure to heat. India is already hard-hit by climate change. Extreme heat is common in May, and the past months were the hottest across much of the c...

In electricity's early days, voltage was known as electromotive force (emf). This is why in equations such as Ohm's Law, voltage is represented by the symbol E. Example of voltage in a simple direct current (dc) circuit: In this dc circuit, the switch is closed (turned ON). Voltage...
因荒漠化造成的直接经济损失约为541亿人民币。防治土地荒漠化的措施主要有() ①大量外迁人口,以减轻人口对土地的压力 ②开发深层地下水,扩大农田灌溉面积 ③大力开发利用太阳能、风能和水能,解决农村能源问题 ④扩大植被覆盖率,设置沙障,育草固沙 ⑤调整土地利用结构,合理放牧,积极营造护田...
As introduced above, a simple description of voltage would be “the ability to cause electricity to flow.” If you’re like most people, you have trouble envisioning what voltage is since you can’t view it directly with your eyes. To understand voltage, you must first understand electricity...
A warmer planet doesn’t just raise temperatures. From wildfires to flooding to coral bleaching, here are some real-world implications.
The silicon is insulating at room temperature, but conducts electricity when it's very hot. It's a semiconductor, whose conductivity changes based on the environment. This special ability makes semiconductors the perfect brains for electronic devices. Circuits of small semiconductor switches, called ...
