Enthalpy is <span>a thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume. So don't know if this helps you...</span>
<span>The answer is

It was by far "warm and wet growing seasons" that was the most important factor in terms of the South's economic development. Cotton and tobacco were the biggest exports.
Explanation:
These crops created tons of cash, had massive markets round the world, however required a stable and enormous hands to grow and harvest them.The yank South is understood for its long, hot summers, and wealthy soils in stream valleys creating it a perfect location for growing cotton. the various southern seaports and riverside docks allowed shipping cotton to remote destinations. By 1860, Southern plantations equipped seventy fifth of the world's cotton, with shipments from Houston, city, Charleston, Mobile, Savannah, and some different ports. The unquenchable European demand for cotton was a results of the commercial Revolution that created the machinery and factories to method raw cotton into vesture that was higher and cheaper than hand-made product.
Both the batteries and fuel cells are portable resources, which transforms the chemical energy into electrical energy.
A battery will produce electricity from the energy it has accumulated inside the battery, while a fuel cell produces the electricity from the fuel in an external fuel tank. This signifies that while a battery may run dead, a fuel cell will produce electricity as long as there is a supply of fuel.
The change in internal energy that accompanies the transfer of heat (q) or work (w), into or out of a system can be calculated using the following equation: Note the value of heat and work as they are transferred into or out of a system.
