Students studied the effect of surface area on the rate of evaporation. Students poured 100 ml of water into a cup. The surface area of the water in the cup was 40 cm². Students poured 100 ml of water into a bowl. The surface area of the water in the bowl was 80 cm².   Students then placed a fan blowing directly across the cup and the bowl. After 60 minutes, the amount of water remaining in each container was recorded in Table 1.

Which container had the largest surface area?

• The cup had the largest surface area.

• The bowl had the largest surface area.

• They had the same surface area.

• That information was not given.

Waves are back-and-forth motions that transmit kinetic energy. Most types of waves travel through matter. Waves transmit kinetic energy through the matter. The waves do not transmit the matter or the particles of the matter. The substance through which the wave travels is called the medium. Waves are produced when some type of force produces a vibration. The two major types of waves are longitudinal waves and transverse waves. In a longitudinal wave, the particles of the medium vibrate parallel to the direction of wave motion. See Figure 1. Sound waves are longitudinal waves. In a transverse wave, the particles of the medium vibrate perpendicular to the direction of wave motion. See Figure 2. Light waves are transverse waves. Which of the following statements is true?

• Waves transmit matter.

• Waves transmit particles.

• Waves transmit substances.

• Waves transmit energy.
