Liquid water at 25°c and 1 bar fills a rigid vessel. if heat is added to the water until its temperature reaches 50°c, what pressure is developed? the average value of β between 25 and 50°c is 36.2 × 10−5k−1. the value of κ at 1 bar and 50°c is 4.42 × 10−5bar−1, and may be assumed to be independent of p. the specific volume of liquid water at 25°c is 1.0030 cm3·g−1

The developed pressure is 205.75 bar.

Explanation:

Given that,

Temperature of water =25°C = 273+25 = 298 K

Pressure = 1 bar

Increases temperature = 50°C = 273+50 = 323 K

Value of

Value of

Specific volume of liquid = 1.0030 cm³/g

We need to calculate the final pressure

Using formula for constant volume change

Put the value into the formula

Hence, The developed pressure is 205.75 bar.
