Suppose the Kelvin temperature (as measured by a reliable sensor) of a 9.0000 mol sample of gas in a rigid 5L tank is doubled. It is observed that the pressure increased to 2.1 times its original value. Which of the following statements could explain the observed result. (select all that apply)

No gas escapes and the gas obeys the ideal gas law.

The pressure reading for the final pressure is too high due to instrument malfunction

Some of the gas reacts with impurities in the tank so that the net moles of gas is unchanged

The pressure reading for the final pressure is too low due to instrument malfunction

Some of the gas reacts with impurities in the tank to form additional total moles of gas

Some gas leaks into the tank during heating assuming P is less than external pressure

Some gas escapes the tank during heating assuming P is greater than external pressure

Some of the gas reacts with impurities in the tank to reduce the total moles of gas

Solutions

Expert Solution

The ideal gas equation is

pV = nRT

variables are pressure (P), volume (V), number of mole of gas (n), and temperature (T)

R is gas constant

Pressure is proportional to temperature, if the number of moles and the volume are constant

here reliable sensor is used. so there is no possiblity of malfunciton in temperature mesurment

and rigid container is used , so there is no possiblity of gas leakage.

statement doesnot provide about the pressure measuement and the impurties.

Hence,

No gas escapes and the gas obeys the ideal gas law.

The pressure reading for the final pressure is too high due to instrument malfunction

these two statements can apply for the above result
