Heat makes atoms/molecules vibrate more. This means that they take up more space - this means the item expands in size.
Mechanical weathering
It's burned. When it burns it creates a big volume of gasses. The force of these gasses expanding is then turned into mechanical energy.
By burning the coal. The stored chemical eneregy is converted to heat energy. That may be used to create steam. Expanding steam pushes a piston or turbine, converting the heat energy to mechanical energy.
Engines use fuel to produce mechanical energy. For instance, a car's internal combustion engine uses chemical energy stored in fuel to turn a drive shaft.The idea of internal combustion is to burn the compressed mixture of fuel and air to produce expanding gas to convert into mechanical energy.
An example of heat energy converting to mechanical energy is a steam engine. In a steam engine, heat energy from burning fuel is used to boil water and produce steam. The expanding steam pushes against pistons, creating mechanical energy that can be used to power machinery.
Mechanical energy (firing pin striking primer) that causes a release of stored Chemical Energy, that becomes Heat Energy (buring gunpowder creates expanding gasses) that becomes Mechanical Energy- shot is pushed out of barrel.
What are three agents or causes of mechanical weathering?
Ice wedging is a form of mechanical weathering caused by water entering cracks in rocks, freezing, expanding, and eventually causing the rock to break apart. Living organisms can also contribute to weathering by burrowing, expanding their roots, or releasing acids that break down rocks chemically. The combination of ice wedging and biological weathering can accelerate the breakdown of rocks and contribute to soil formation.
Expanding steam energy involves utilizing the energy released from the expansion of high-pressure steam to perform mechanical work. This is commonly used in steam turbines to generate electricity in power plants. As steam expands, its pressure drops, and the energy is converted into rotational motion to drive a generator.
In a steam engine, the energy transformation involves converting the potential energy contained in steam (thermal energy) into mechanical energy. This process involves the steam expanding and pushing against a piston, which in turn drives a crankshaft to produce rotational mechanical energy.
A jack hammer creates longitudinal waves, which are mechanical waves that travel through a medium by compressing and expanding the material in the same direction as the wave's motion.
