The volume of an ideal gas at a pressure of 77cmHg and temperature 60oC is 24cm3. If the temperature and pressure are increased to 98oC
and 81cmhg respectively, calculate the new volume of the gas
and 81cmhg respectively, calculate the new volume of the gas
411.5cm3
267.1cm3
254.2cm3
112.7cm3
Explication
V2 = \(\frac{P_1V_1T_2}{P_2T_1} = \frac{77 \times 240 \times 371}{81 \times 333}\)
= 254.2cm3
= 254.2cm3
