If the pressure of a gas is 2.000 × 104 kpa, what is its pressure in atm? 26.32 atm 197.4 atm 1.013 ´ 106 atm 2.026 ´ 106 atm

Answer : The correct option is, 197.4 atm

Solution :

We are given pressure of gas is and the conversion used for the calculation is,

1 atm = 101.325 kPa

or,

As, 101.325 kPa pressure of a gas = 1 atm

So, pressure of a gas =

Therefore, the pressure in atm is, 197.4 atm

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.
