1. How many kilograms of air are in your room? Assume your room is 10 m× 10 m× 3.0 m. The density of air at sea level is about 1.2 kg / m^3.
2. What is the density of a metallic block which is 10 cm× 8 cm× 5 cm if its mass is 4.8 kg ?
3. Water has a surface tension of 0.4 N / m. in a 3 mm diameter vertical tube if the liquid rises 6 mm above the liquid outside the tube, calculate the contact angle.
4. Find the density if 51 g of gasoline occupy 75 cm^3 ? Express your answer in kg / m^3.
