Correct answer: D
Explanation
The correct answer is option 4 i.e. 1 atm = 1.013 bar.
The relation between atm (atmosphere) and bar is that 1 atm is equivalent to 1.01325 bar. This means that 1 bar is slightly less than 1 atmosphere. Specifically, 1 bar is equal to 0.9869 atm. The bar is a metric unit of pressure commonly used in meteorology and other sciences, while the atmosphere is a unit often used in various scientific contexts, including chemistry and physics. Both units are used to measure atmospheric pressure and can be converted between each other.
