1. When the pressure of water in a press cylinder is released from 1000 × 10⁵
N/m²
to 1 bar, there was a 4.11 percentage increase in specific volume while the temperature remained constant. Determine the average value of bulk modulus for water in this range.

2. When water was heated in a rigid vessel the pressure rise was 14.49 × 106 N/m2. Assuming that the vessel volume did not increase due to the increase in temperature or due to the stress induced, determine the percentage change in density. Assume E_v
= 2300 × 10⁶
N/m²
