 1 Pure water boils at 100C at sea level. Now you may recall that if a solute is added to water it increases the boiling point slightly. One day, Jonathan decided to see if this was really true (he didn't believe it). He added some salt to a beaker of water and used an accurate thermometer to measure the temperature at which the water boiled. He found that the boiling point was raised to101.4C. He had measured the boiling point of pure water earlier and found it to be99.8C by his thermometer. How manyC did the boiling point increase in his experiment?
 2 Two different rocks from near a recent volcanic eruption are compared. Sample A is a rock with a mass of640grams and a volume of327cm3, and sample B has a mass of920grams and a volume of509cm3. Which sample is denser and by how much? Round your answer to the nearest hundredth.
 3 Newton's 2nd law states that force (in newtons-N) equals mass (in kg) times acceleration (in m/s2). What is the force on a wall resulting from a1.7-kg brick hitting the wall and decelerating at9.02m/s2?
 4 Gesetzt den Fall in einer Gegend beträgt das Verhältnis der anfänglichen Kunden zu den späteren Kunden18/6, about how many primary consumers would you expect in a population of10,459primary and secondary consumers?
 5 At one particular point on the earth's crust, measurements by Testo-Findo, Ltd., indicated that the temperature rose1.5C for every50m increase in depth. The test depths were achieved by drilling. If the temperature at the surface of the crust is21.8C, what is the temperature expected to be at1700m?
 6 The momentum (in kg m/s) of an object depends on the object's mass and velocity (momentum = mass times velocity). Suppose you are a goalkeeper on a soccer team. The ball comes at you with a velocity17m/s. If the ball has a mass of1,257grams, what is the momentum of the ball when it strikes your hand as you deflect it from the goal in an incredible diving save?_________ kg m/s
