explain heat energy ,
with th help of a steam boat .
The heart of the steamboat is the steam engine which makes it work. Many different designs and variations of steam engines were developed and tried during the era of steam ships. The basic Watt engine was the most important design. First, water is fed to a boiler, which heats it up until it produces steam. The steam is then fed into a piston cylinder. It pushes the piston up to the top of its stroke. When it reaches the top, a valve is opened in the side of the cylinder to vent out the steam. The valve drops down again, and the whole cycle starts again. In this process large amount of heat is generated which makes the Paddle Wheel move.
