Heat is a form of energy obtained due to the random motion of molecules in a substance but temperature is a quantity which decided the direction of flow of heat when two bodies at different temperature are placed in contact. Also, burning wood releases a lot of smoke which pollutes the atmosphere. The icebergs of dark land and oceans will melt, so the dark land and oceans will become uncovered and will absorb more heat radiations coming from sun, increasing the green house effect further. You will hear a sound. The two groups in which various sources of energy are classified are renewable or non-conventional sources of energy and non-renewable or conventional sources of energy. A food chain shows the feeding relationship between different living things in a particular environment or habitat.

The steam is used to rotate the turbine which in turn rotates the armature of a generator in a magnetic field and thus produces electricity. Dams are constructed across a narrow opening to the sea to harness tidal energy and produce electricity. The most important thing is when we choose effective guidance, it leads us to the proper and accurate path with comparatively more pace in a lesser time and eventually students can then take out time from their schedule to study other subjects as well, specially the subjects in which they are comparatively weaker. What is in this article? The shaft of the turbine is connected to the armature of an electric generator or dynamo. If the bottle is completely filled and tightly closed, there is no space for water to expand, and hence, the bottle may burst.

Click on the links to download chapters. When you beat an object, you can feel its vibrations with the help of your sense of touch. Part 2 For Class 10 for Rs. As the freezing mixture cools water in the central portion of the cylinder, water contracts and its density increases, consequently it sinks to the bottom, thereby causing the reading of the lower thermometer T 2 to fall rapidly. When temperature falls, the top layer of water in a pond contracts becomes denser and sinks to the bottom.
