Concept explainers
(a)
Interpretation:
The reason as to why the tank gets purged is to be stated.
Concept introduction:
Combustion is the process of burning of chemical substances. The combustion reactions are exothermic reactions that usually occur in the presence of oxygen. Consequently, the large amount of energy is released during the process.
(b)
Interpretation:
The gauge pressure to which the tank must be charged if the purge is to be done in one charge-vent cycle is to be calculated. The mass of nitrogen used during the process is to be calculated.
Concept introduction:
An ideal gas equation is derived from the combination of Charles’s law, Boyle’s
The general expression for an ideal gas is shown below.
The expression exhibits that an
The gauge pressure to which the tank must be charged is calculated by the formula,
(c)
Interpretation:
The number of charge-vent cycles required for the process is to be calculated. The total mass of nitrogen used is to be calculated.
Concept introduction:
An ideal gas equation is derived from the combination of Charles’s law, Boyle’s law and Avogadro law.
The general expression for an ideal gas is shown below.
The expression exhibits that an ideal gas law relies on the temperature, pressure, volume and moles of gas.
(d)
Interpretation:
The explanation corresponding to the given statement that multiple cycles at a lower gas pressure are preferable to a single cycle is to be stated. The probable disadvantage of multiple cycles is to be stated.
Concept introduction:
An ideal gas equation is derived from the combination of Charles’s law, Boyle’s law and Avogadro law.
The general expression for an ideal gas is shown below.
The expression exhibits that the ideal gas law relies on the temperature, pressure, volume and moles of gas.
