Butane-fueled cigarette lighters, which give hundreds oflights each, typically contain 4 to 5 g butane (C4H10),which is confined in a 10-mL plastic container and exertsa pressure of 3.0 atm at room temperature (25°C). Thebutane boils at-0.5°C under normal pressure. Butanelighters have been known to explode during use, inflictingserious injury. A person hoping to end such accidents suggests that there be less butane placed in the lighters so thatthe pressure inside them does not exceed 1.0 atm. Estimatehow many grams of butane would be contained in such alighter.

Principal Quantities and EOS

A physical quantity represents the physical state of a system. It is expressed as the product of a number and unit. The basic quantities used in science are length, mass, and time. The principal quantities are the quantities that are independent of other quantities.
