Why the second law of thermodynamics is not violated when the hood of a car gets hot while the car is moving?

The energy created as a result of the internal combustion equals the amount of energy that was needed to move the automobile. See Below.
The increase in the internal energy of a system is equal to the amount of energy added by heating the system, minus the amount lost as a result of the work done by the system on its surroundings.
aka Conservation of Energy.

∙ 9y agoThe Kelvin- Planck Statement of the Second Law of Thermodynamics requires that some of the fuel's heat released at high temperature be rejected to one or more low temperature heat sinks , such as the radiator. The thermal efficiency must be less than 100 percent.
The Claussius Statement requires that the coolant be cooler than the engine .

What branch of physics explains why tile floor fell cold to the barefoot while carpet feels warm?
Thermodynamics. The basics of Thermodynamics will explain why materials with two different Coefficients of Conductivity will "FEEL" different to the human touch.
Moving the ball 10-12 inches per bounce and keeping control of it while moving?
dribbling
Do objects have inertia only when they are moving?
Inertia is the tendency of an object to resist a change in motion. An object would have inertia while moving and also while at rest.
What forces must be overcome while on a moving swing?
Gravity must be overcome.
Two very popular and common objects have the same function but one has thousands of moving parts while the other has absolutely no moving parts What are they?
An hourglass and a sundial.

Is a refrigerator makes objects colder an example of the first law of thermodynamics?
The First Law of Thermodynamics is never violated, so yes (everything is an example of it...). In the case of a refrigerator, the inside of the refrigerator cools down, while the surroundings heat up. Also, energy is used to pump the heat; this is converted into additional heat. Total energy is, of course, conserved.

What is protocol for a probation drug test?
In Florida, go in urinate in the cup while you are watched and you get told if you violated it or not.
How does a tractor cut grass while moving?
A tractor employers blades that revolve to cut grass while moving.
Why does cooling happen?
Because of the second law of thermodynamics , law of entropy. "when energy flows from a high-temperature object to a low-temperature object, the source temperature is decreased while the sink temperature is increased; hence temperature differences tend to diminish over time."
Are your charges still considered pending while you are on unsupervised probation?
No, but if the unsupervised probation is violated for a new charge then it can be revoked.
