Chapter 1, Problem 1.34E

A gasoline station in Manila, Philippines, charges 38.46 pesos per liter of unleaded gasoline at a time when one US. dollar (USD) buys 47.15 pesos (PHP). The car you are driving has a gas tank with a capacity of 14 U.S. gallons and gets 24 miles per gallon. (a) What is the cost of unleaded gasoline in Manila in USD per gallon? (b) How much would a tankful of unleaded gasoline for your car cost in USD? (c) Suppose that you have only PHP 1255 (a day's wage for an elementary school teacher) and the car's tank is almost empty. How many miles can you expect to drive if you spend all your money on gasoline?

1. A thermometer is taken from an inside room to the outside, the air temperature is 5°F . After 1 minute, the thermometer reads 55°F , after 5 minutes the reading is 30°F. What is the initial temperature at the room?

4 Chemistry is the science of the structure and interactions of matter. The INCORRECT alternative is: D) All living and nonliving things consist of matter, which is anything that occupies space and has mass. Mass is the amount of matter in any object, which does not change. Weight, the force of gravity acting on matter, does change. When objects are farther from Earth, the pull of gravity is strong; this is why the weight of an astronaut is close to zero in outer space.   5. Structure of Atoms: each element is made up of atoms, the smallest units of matter that retain the properties and characteristics of the element. Is CORRECT to affirm that: B) One subatomic particle composed of individual atoms. Only three types of subatomic particles are important for understanding the chemical reactions in the human body: protons, neutrons, and electrons. The dense central core of an atom is its nucleus. Within the nucleus are positively charged neutrons (p+) and uncharged (neutral) protons…
