How Does Temperature Regulation In An Electric Iron Work?
The working of an electric iron is very simple – it draws electricity from the mains and heats a coil inside. This heat is then transferred to the bottom plate, which is pressed against the clothing to remove wrinkles. It is the...

How Do We Know Temperatures from Thousands of Years Ago?
Researchers estimate ancient temperatures using data from climate proxy records, i.e., indirect methods to measure temperature through natural archives, such as coral skeletons, tree rings, glacial ice cores, and so on. For example, the...

How Do Radio Stations Transmit The Name Of The Song Thats Currently Playing?
The song name is displayed on the radio with the help of a specific communications protocol called the Radio Data System, which embeds small bits of information in FM broadcast signals. RDS allows broadcasters to send much more than just...

Feels Like Temperature: What It Really Means and How It's Calculated
Measuring actual temperature consists of recording the air temperature from a thermometer that has been kept inside a Stevenson screen or by using any other appropriate instrument. “Feels like temperature,†on the other hand, is a...

Entropy : Why is it Predicted to Cause the Heat Death of the Universe?
Heat death of the universe, also called The Big Chill or Big Freeze, will happen when the entropy of the universe will be so high that everything and everyone that lives in it will perish. This will happen because an organism living in...

Germination: How Does A Seed Become A Plant?
Seed grow into plants through the process of germination. Germination requires optimum sunlight, temperature, water and air for the seed to turn into a plant. Isn’t it amazing that a tree as tall as a building can emerge from just a tiny...

Does Water Expand When It Freezes?
Yes, water expands when it freezes. Note that the word expands here indicates an increase in volume. So, a technically sound way to put it would bewaters volume increases when it freezes. This statement is accurate, and you can test its...

Does "100% Humidity" Mean Air Has Turned to Water?
Humidity is simply a measure of how "wet" the air is in a specific place, or the amount of water vapor present in the air. However, it's important to note that humidity is an umbrella term that can refer to three different types of...

Climate Change and Global Warming: Explained in Simple Words for Beginners
The term climate change is used to denote the long-term changes in the weather patterns in a given region. Another term often interchanged with climate change is global warming. Global warming is formally defined as a rise in Earth's...

Can We Harness Electricity From Lightning?
It is very difficult to harness power from lightning power because of its volatile nature, sporadic appearance and uneven geographical distribution. Lightning is one of the incredible forces of nature. A single bolt of it carries a few...

Can Metals Exist as Gases?
Yes, metals can exist in gaseous forms. To illustrate, let's consider lead, which has a boiling point of 1740°C. When heated past its melting point of 327°C, lead turns into a gas at 1740°C. Another notable example is mercury, which...

Why Is Space Cold If There Are So Many Stars?
Space is filled with countless stars, all of which radiate enormous amounts of heat. These stars are tens of thousands of times bigger than our own sun. Still, space is considered to be cold. Why is that? If there are so many hot burning...

Why Does Water Evaporate at Room Temperature?
Water evaporates at room temperature because the molecules at the top of the liquid have less intermolecular attraction than those within the bulk. When the top layer is exposed to sunlight, some molecules gain enough kinetic energy to...

Why Do Bubbles Form In A Glass Of Water?
Water especially the one which flows through the pipe contains atmospheric gases, such as nitrogen and oxygen, dissolved in it. As the glass filled with water sits out for a few hours, its temperature rises slightly (water gets warmer),...

Why Aren't We Using Nuclear Fusion To Solve Our Energy Crisis?
We aren’t using nuclear fusion to generate power yet because it is incredibly difficult to sustain a fusion reaction. The energy requirements are very high, and it is hard to find materials that can withstand such high temperatures....

Why Are the Tropics Hotter than The Equator?
The hottest parts of the world do not lie on the Equator (as our assumption would suggest) but rather around the tropics, i.e., the areas that lie above and below the Equator. Whats the reason behind this? The answer to this question...

Why Are Some Ice Cubes Cloudy While Others Are Clear?
The clarity of ice cubes is determined by the temperature of the water used to make them. Warmer water contains more impurities, which are released when the water is cooled and frozen. Ice cubes made from distilled or boiled water are...
