Question

The vapor pressure of water increases slowly at first and then started increasing rapidly ,when subjected to heating in closed system. As the water reaches the boiling point of ${100}^o$C, the vapor pressure reaches $1$atm. Choose the model that best describes the increase in vapor pressure as water is heated to its boiling point

• A. Linear
• B. Quadratic
• C. Polynomial
• D. Exponential

Answer 1

The correct option is A Linear

Since the system is a closed system. The pressure increases slowly and increased rapidly and reached the boiling point of $100$ degree Celsius.
So, in quadratic, polynomial, exponential form the graph will show the increase and decreasing curve for any system. But only in linear we get the straight line.
Therefore, linear is the best describes the increase in vapor pressure as water is heated to its boiling point.
