A ring weighing 9.45 g is placed in a graduated cylinder containing 25.3 mL of water. After the ring is added to the cylinder the water rises to 27.4 mL. What metal is the ring made out of? Assume the ring is a single metal.

Titanium metal.

Explanation:

Mass of ring = 9.45 g

Initial Volume = 25.3 mL

Final Volume = 27.4 mL

Volume of ring = 27.4 - 25.3 = 2.1mL

Density = Mass / Volume

Density = 9.45 / 2.1

Density = 4.5g/ml

Since, the ring is a single metal, we look for the metal that has a density of 4.5g/ml. This metal is the Titanium metal.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
