For an explosion to occur, you typically need three key factors: fuel, oxygen, and an ignition source. The fuel could be anything combustible like gas or chemicals, while oxygen provides the necessary oxidizer for combustion. An ignition source, such as heat, a spark, or a flame, is needed to initiate the reaction between the fuel and oxygen, leading to a rapid release of energy in the form of an explosion.

Yes, that's the basic cause of convection.
When its too dry outside the heat could cause it to catch on fire
Engine running rich. Get this fixed ASAP and do not drive until you do. Serious damage will occur to the engine. If you have electronic fuel ignition and you pump your gas pedal before starting, this can add un-burned fuel to your engine oil.
Hormone imbalance can occur due to various reasons. It could be genetic. Lifestyle can also be a major cause for example drug intake, stress, bad eating habits. Another cause could be environmental changes.
Carbon fibers themselves are not flammable however a binder or Resin used to form a shape or structure is flammable. Although Carbon Fiber structures are not easily ignited once the temperature exceeds appx. 550 F ignition can occur. In the case of carbon fiber components in a car, the initial ignition source can be the gasoline on-board, followed up by the ignition of the carbon fiber components with the higher ignition temperatures.
Not start or not turn over. The engine needs 3 things to run. Air/Fuel/Spark. The spark must also occur at the correct time. If it will not turn over, supect the battery, starter, ignition switch, or corroded or loose cables.
The change in the Doppler effect does not cause a change in the frequency of the wave source itself; it only affects how the frequency of the wave is perceived by an observer in relative motion to the source.
The screwdriver could slip and cause harm to the technician or to nearby individuals.
Combustion requires three main components: fuel, heat, and oxygen. The fuel provides the source of energy, heat initiates the reaction, and oxygen serves as the oxidizer for the combustion process to occur. Without any of these components, combustion cannot take place.
Coal dust particles have a larger surface area compared to lumps of coal, allowing for faster combustion and easier ignition. The dispersed nature of dust particles also creates more opportunities for them to come into contact with an ignition source, increasing the likelihood of an explosion.
