Paragraph Styles 1. If the mass of air inside a room is 1 kg, what is the volume of the air? Use Table 11.1 on page 290 in the textbook. Hint: Review Sample Question 1 in the Unit VI Lesson. 2. A massless cube container holds water whose density is 1000 kg/m'. The length of the side of the cube is 7 meters. What is the mass of the water? Hint: The volume of a cube is obtained by R x R x R, where R is the length of the side of the cube. Use the formula mass = density x volume. 3. A 10-kg piece of metal displaces 0.002 m of water when submerged. What is the density of the metal? Hint: Use the formula mass = density x volume. 4. The pressure acting on a floating piece of wood is measured by 12345 Pascal, and its surface area is 0.6789 m. What is the magnitude of the force in Newtons? Hint: Review Example 2 on page 292 in the textbook. 5. A boy's height is 1.76 meters. The vertical distance from his head to his heart is measured as 0.39 m. Find the blood pressure difference between the blood pressure in the anterior tibial artery at the foot and the blood pressure in the aorta at the heart. What is the blood pressure difference between them? The density of blood is 1060 kg/m, and the blood is assumed as being a static fluid. Hint: Review Sample Question 2 in the Unit VI Lesson. 6. You bought a 1 kg solid gold statue from a merchant in Italy while you are on vacation. When you get home, you decided to test if this statue is real gold or not. After submerging the gold statue in a large water container, you will measure the volume of displaced water. What is the expected volume if the statue is made of pure gold? For the density of gold, use Table 11.1 on page 290 in the textbook. 7. A traveler at the North Pole measured the temperature as -40 C. Can you convert this temperature to the Fahrenheit scale? What is the temperature on the Kelvin scale? Hint: Use the converting formula: OF 1.8.C + 32. The relation between the Celsius scale and the Kelvin scale is K = .C + 273.15
