Passage IV
Atmospheres (atm), torr, and kilopascals (kPa) are common units of pressure. Figure 1 can be used to convert between torr and kPa. A pressure of 1 atm is indicated in Figure 1.
Figure 2 shows how boiling point (BP) varies with atmospheric pressure for 3 compounds: acetaldehyde, acetone, and pentane. The unit of pressure is torr.
Figure 3 shows how BP varies with atmospheric pressure for 3 other compounds: ethanol, methanol, and methyl acetate. The unit of pressure is kPa.
25. Based on Figure 1, a pressure of 2 atm would correspond to a pressure in torr that is:
Your Answer is
Correct Answer is D
Explanation
As can be seen from figure 1, 1 atm is approximately equal to 760 torr, so 2 atm is approximately equal to 1520 torr, so option D is the closest
