Ответ:
The correct answer is at 273 K and at 2.0 atm.
Explanation:
Volume of a gas depends on temperature and pressure of the gas. The laws used to relate volume with temperature and pressure are Charles' Law and Boyle's Law respectively.
Charles' Law: This law states that the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.Mathematically,
As, the volume of the gas increases, the temperature of the gas also increases and vice-versa.
Boyle's Law: This law states that pressure of the is inversely proportional to the volume of the gas at constant temperature and number of moles.Mathematically,
As, the volume decreases, the pressure of the gas increases and vice-versa.
So, for the volume to decrease, the temperature must be minimum and pressure must be maximum.
Hence, from the given options, the correct one is at 273 K and at 2.0 atm.
