YES. When hamming a nail/spike, the nail encounters friction from target rubbing against the sides of the spike and also from taring through the target.
Sound wave
thermal, electrical, chemical, or radiation
Yes, friction produces heat.
no, but it traps heat b/w its layers
It is the heat resulting from compressing a gas.
Both planets receive a small amount of energy from the Sun, but the main source of energy is due to gravitational compression or the Kelvin-Helmholtz mechanism. [See related link]
The engine compression creates enough heat for the fuel to combust.The engine compression creates enough heat for the fuel to combust.
1.decay of radioactive isotopes 2.bombardment by meteorites 3.compression by overlying materials
Diesel engines rely on heat and high compression to ignite fuel.
Pressure...more so...gravitational compression and the decay of radioactive isotopes such as potassium.
the sun is our source of heat
The source of the Earth's internal heat is a result of gravitational compression and to a much lesser extent, the decay of radioactive isotopes.The heat present in the Earth is due to several factors.The first source of heat is from the remnants of heat from impacts with planetesimals early in Earth's history. Impacts with large bodies such as these (including the impact which led to the formation of the moon) trapped the thermal energy of the collision in the surrounding rock of the planet, and may have been enough in certain circumstances to completely melt the early Earth.The second source of heat is also a remnant of an early Earth event known as the Iron Catastrophe. With much of early Earth still molten, denser metals, particularly iron and nickel, migrated to the center of the planet. Tremendous amounts of frictional heat was created, enough to completely melt the planet once again.The third source of heat in the Earth is from compression due to gravity.The fourth and final source of heat in the Earth is from the decay of radioactive elements. This source of heat is gradually declining due the decreasing amounts of radioactive isotopes, the decrease being caused by the decay.

Ok, HOW is Heat-Of Work. That's 18Btu/lb And HOC is Heat-Of Compression. That's 20Btu/lb.
They are not needed, the high compression creates enough heat for the air fuel mixture to self ignite.They are not needed, the high compression creates enough heat for the air fuel mixture to self ignite.
