If a tennis ball has a pressure of 200 atm at a temperature of 27oC, what pressure in atm will the tennis ball have if the temperature of the gas increased to 77oC?

the dissolution of polymer can be thermodynamically described in 2 steps.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
