7. A submarine cruises through the water at a speed of 26.4 nautical miles per hour. If there are 1.15 regular miles per nautical mile, what is the submarine's speed in terms of meters per second? 8. A company delivering crates of soap ships their cargo on pallets. A single pallet contains 6.00 crates, with each crate containing 50.0 bars, and each bar weighing 8.00 ounces. How many kilograms of soap are there in 2.00 pallets? 9. How many grams of a gas can occupy a cylinder with a diameter of 1.5 dm and a height of 8.00 in if the gas has a density of 2.56 g/L? 10. How many calories of energy are required to raise the temperature of 121 g of water from 18°C to 47°C? 11. A student doing a lab found that a 81.0 g piece of silver metal had a specific heat of 0.233 J/g°C when he applied 1.57 kJ of energy to it. However, he forgot to record the initial temperature of his sample. Calculate the initial temperature of the student's sample if the final temperature was 103°C. Give the temperature in Fahrenheit. 12. If it takes 3.10 kJ of energy to raise the temperature of 110 g of an unknown metal from 16°C to 54°C, what is the metal's specific heat?
