If equal masses of O2 and N2 are placed in separate containers of equal volume at the same temperature, The statement (a) is true i.e. the pressure in the flask containing N2 is greater than that in the flask containing O2.
How hot or cold something is can be expressed numerically using the physical concept of temperature. Temperature is measured with a thermometer. Different temperature scales, which traditionally established various reference points and thermometric materials, are used to calibrate thermometers. The most widely used scales are the Kelvin scale (K), which is mostly used in science, the Fahrenheit scale (°F), and the Celsius scale, also referred to as centigrade and denoted by the unit symbol °C. The kelvin is one of the seven base units in the International System of Units (SI). On the thermodynamic temperature scale, absolute zero, also known as 0 kelvin, or 273.15 °C, is the lowest temperature. The third law of thermodynamics recognizes that it can only be very nearly attained experimentally and that it cannot actually be reached. It would be challenging for a body to produce heat at such temperature. Temperature is a crucial factor in all branches of natural science, including physics, chemistry, Earth science, astronomy, biology, ecology, material science, metallurgy, mechanical engineering.
