question 28

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 $1530 \mathrm { kPa }$ (kiloPascals) when the number of moles is 6 , the temperature is $340 ^ { \circ } \mathrm { Kelvin }$ , and the volume is $720 \mathrm { cc }$ , find the pressure when the number of moles is 7 , the temperature is $310 ^ { \circ } \mathrm { K }$ , and the volume is $420 \mathrm { cc }$ .

• A) \(1350 \mathrm { kPa }\)
• B) \(1395 \mathrm { kPa }\)
• C) \(2880 \mathrm { kPa }\)
• D) \(2790 \mathrm { kPa }\)
