Heat lost = mcΔT, where m is the mass of iron , c is the specific heat capacity of iron, and ΔT is the change in temperature.
Mass of iron = 350 g, specific heat capacity = 0.450 J/gC while;
change in temperature = 54.1 - 22.4 = 31.7
Hence; heat = 350 × 0.450 × 31.7
= 4992.75 J or 4.993 kJ
The correct answer is 1atm.

What is Kinetic theory of gases?</h3>
A lot of the fundamental ideas of thermodynamics were established with the help of the kinetic theory of gases, a straightforward yet historically significant classical model of the thermodynamic behaviour of gases. According to the model, a gas is made up of numerous identical submicroscopic particles (atoms or molecules) that are all moving rapidly and randomly. It is considered that they are substantially smaller in size than the particle spacing on average. Random elastic collisions between the particles and with the container's walls occur between the particles. The simplest form of the model only takes into account the interactions within the ideal gas.
