Endothermic and Exothermic Reactions
An exothermic reaction gives off energy to the surroundings; like a fire giving off heat. An endothermic reaction takes in energy from the surroundings; like a snowman melting.
What Are Dilutions
In this video, we will look at what dilutions are in chemistry, how to calculate them using a very easy equation and even extending to multiple dilutions which are called […]
Unicellular vs Multicellular
Did you know that some organisms exist of just one cell? These simple organisms, like amoeba, are unicellular. They depend on simple diffusion for life.
Sound in the Sea: Ocean Acoustics
Sometimes the earth is so noisy… roads, aeroplanes, volcanoes, construction work… but have you ever thought about how noisy it must be underwater, for the poor marine life that cannot […]
Plate Tectonics: Chemistry for All
Plate tectonics and continental drifts the theory of plate tectonics had enabled us to explain how the contents drift and why there are mountains, earthquakes, volcanoes and so much more.
