Atoms and molecules are always in motion. Temperature reflects how intensely they move. The faster they move, the hotter it gets, and vice versa, right down to absolute zero, where everything stops. To define temperature, there are different scales. Authors: ZDF/TerraX plus/Bilderfest/Paul Grumer/M
Throughout earth's history, climate has been akin to a rollercoaster ride. The "fever curve" of our planet shows the global temperature fluctuations to date - reconstructed using historical climate data. Author: ZDF/Terra X/Gruppe 5/Luise Wagner, Jonas Sichert, Andreas Hougardy Redub: alugha Cli

This video segment adapted from NOVA scienceNOW highlights research that supports the idea that warmer oceans generate and sustain more intense hurricanes. Ongoing monitoring of sea surface temperature (SST) has supplied evidence that the world's oceans warmed 0.5°C between 1970 and 2005. Because hu

You might have noticed that if you are trying to boil a lot of water it takes longer than if you only wish to boil a small amount of water. This is all because of something called ‘heat capacity’. Keep watching to learn more. Before we get into the details, it is important to realise that there i
Photosynthesis is a chemical reaction that is fundamental to life. In this video we are going to have a look at the factors that affect the rate of photosynthesis. There are 3 main factors: light intensity, carbon dioxide concentration and also temperature. These factors are called limiting fact
The boiling temperatures of the hydrocarbons are explained. A short review of the basics is at the beginning. The influence of the molecular surface on the boiling temperatures is also explained. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alu

Homeostasis is a term first defined by Claude Bernard in 1865. It means maintaining a constant internal environment. This is a bit like how our brain works. Sensors all around the body are measuring various things and sending the information back to the brain the brain in does its best to keep all t
