An ideal gas at 14.2 °C and a pressure of 1.97 x 105 Pa occupies a volume of 4.19 m3. (a) How many moles of gas are present? (b) If the volume is raised to 6.60 m3 and the temperature raised to 27.0 °C, what will be the pressure of the gas?
QUESTION 2
a) An air balloon with a volume of 300 m³ and pressure of 450 Pa is floating steadily. After
a while, the pressure in the balloon decreases to 200 Pa causing the balloon to shrink.
What is the new volume of the balloon? (CO3, PO1, C3)
b) A 10 m³ container contains an ideal gas and under a pressure of 3.5 atm is placed in
room temperature (293 K). Assuming the volume of the container is constant, what is
the pressure of gas when the temperature is increased to 308 K? (CO3, PO1, C3)
c) In an internal combustion engine, air at atmospheric pressure is compressed in the
cylinder by a piston to 1/9 of its original volume. Calculate the estimated pressure (in
atm). (CO3, PO1, C3)
d) A sealed metal container contains a gas at 20°C and 1 atm. To what temperature must
the gas be heated for the pressure to double to 2 atm? (Ignore container expansion).
(CO3, PO1, C3)
e) If 60 L of oxygen at 18°C and pressure of 2.5 atm are compressed to 45 L and at the
same time raised to 35°C, what…
