Coal
No, the mass of coal decreases when it is burned due to the release of gases and particles into the atmosphere. The carbon in the coal combines with oxygen to form carbon dioxide, which is released as a gas, contributing to the decrease in mass of the original coal.

There are sustantial amounts of the following Natural Resources located in the Indian subcontinent iron Ore, coal, gem stones, and fertile soil.
Around 1730 in Virginia. See the related link below on history of coal mining. As well, consider American Indian use of coal long before settlements in the Americas. 1730 is an excellent answer regarding industrial U.S. coal mining.

coal mines where the british forced Indian workers to labor.
Controlled parameters are kept constant during an experiment to ensure that the only factor being tested is the variable parameter. Variable parameters, on the other hand, are the factors being purposely changed or manipulated in an experiment to observe their effect on the outcome. Control parameters help eliminate outside influences and provide a clearer understanding of the relationship between the variable and the outcome.
Hybrid parameters are called so, because the parameters have different units. In Z- parameters, all the parameters have units of ohms and in Y- parameters, all parameters have Siemens as units. But in hybrid parameters, we have both ohms and Siemens as units. The other way it is called hybrid is, the independent variables are the input current and output voltage.
