🤔 How it works …….. ⁉
How a steam Engine works
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work.
Until the early 20th century, coal was the world’s favorite fuel and it powered everything from trains and ships to the ill-fated steam planes invented by American scientist Samuel P. Langley, an early rival of the Wright brothers.
A fire where the coal burns. There will be a boiler full of water that the fire heats up to make steam. A cylinder and piston, rather like a bicycle pump but much bigger. Steam from the boiler is piped into the cylinder, causing the piston to move first one way then the other. This in and out movement (which is also known as “reciprocating”) is used to drive… A machine attached to the piston. That could be anything from a water pump to a factory machine… or even a giant steam locomotive running up and down a railroad.

Why Mosquitoes bites to drink blood
The word “mosquito” (formed by mosca and diminutive -ito) is Spanish for “little fly”. Mosquitoes are the world’s deadliest animals, transmitting diseases like malaria, yellow fever, Chikungunya etc that kill hundreds of thousands of people annually.
Only the Female Anopheles mosquitoes bite, to acquire protein to make their eggs. When a mosquito pierces the skin, Mosquito saliva makes our blood vessels dilate, blocks our immune response and flexible lip-like sheath called the labium scrolls up and stays outside as she pushes in six needle-like parts called stylets.
Two of these needles, called maxillae, have tiny teeth. The mosquito uses them to saw through the skin. They’re so sharp you can barely feel the mosquito biting
