1. A 0.1-m3 volume of water is observed to be 0.0982 m3 after a pressure is applied. What is that pressure?
2. How long would it take a small wave to travel under 22-C water a distance of 800 m?
3. The coef?cient of thermal expansion aT allows the expansion of a liquid to be determined using the equation DV- ¼ aTV-DT. Calculate the decrease in 2 m3 of 40-C water if the temperature is lowered by 10-C. What pressure would be needed to cause the same decrease in volume?
