A hiker seals a plastic bag that contains dried fruits before he climbs a mountain. What will most likely happen to the plastic
Sonja [21]
I think the correct answer would be the first option. As the hiker reaches the top of the mountain, the plastic bag would, most likely, expand. Before starting, the plastic bag would have a certain amount of gas particles inside. As the you hike, the pressure would decrease causing for the gas molecules to reestablish equilibrium thus pushing the bag outwards. In other words, expanding the bag. Also, base from the ideal gas equation, PV = nRT, at constant temperature and number of moles, pressure and volume are inversely related. Thus, as the pressure decreases, the volume of the system would increase accordingly.

A 8.5 L sample is collected at 45°C. What will the volume be if the temperature is raised to 70°C? End of exam A. 9.2 L B. 13.2
klasskru [66]

Answer: The correct option is A.

Explanation: To calculate the volume at the end , we use Charles's Law, which states that the volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

V\propto T

or

\frac{V_1}{T_1}=\frac{V_2}{T_2}

  • Initial conditions:

V_1=8.5L

T_1=45^oC=(45+273)K=318K

  • Final conditions:

V_2=?L

T_2=70^oC=(70+273)K=343K

Putting all the values in above equation, we get

\frac{8.5}{318}=\frac{V_2}{343}

V_2=9.2L

Hence, the correct option is A.
