Answer:
1. Acidity, also known as acid reflux, is an ill-health or medical condition caused due to the production of excessive acid in the stomach. Under this condition, the stomach’s acid flows back into the food pipe and causes a burning sensation or pain in the lower chest cavity.

3.The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below
4.CNG stands for compressed natural gas. It is the gaseous product of petroleum and is the first product that is separated during the distillation process. CNG is odorless, tasteless and non-toxic, and is made up of 93.05% methane, nitrogen, carbon dioxide, propane and traces of ethane. It is an environmentally clean alternative fuel, as its combustion process emits a lower percentage of greenhouse gases when compared to other fuels.
5.Purely for 2 reasons. First, due to environment al pollution and second due to fuel scarcity and economics behind it.
To prevent wastage of fuel , during vehicle operation, many inbulit solution being done on vehicle ecu.
Further , even when vehicle parked, there are certain, norms and limits for fuel evaporation is limited. so by every small and better means, nowadays, fuel wastage is protected
