question 139

Multiple Choice

Solve.
-The pressure of a gas varies jointly as the amount of the gas (measured in moles) and the temperature and inversely as the volume of the gas. If the pressure is $1152 \mathrm { kPa }$ (kiloPascals) when the number of moles is 6 , the temperature is $320 ^ { \circ } \mathrm { Kelvin }$ , and the volume is $720 \mathrm { cc }$ , find the pressure when the number of moles is 9 , the temperature is $280 ^ { \circ } \mathrm { K }$ , and the volume is $1080 \mathrm { cc }$ .
