WRITTEN OUTPUT
DIRECTION: Write TRUE if the statement is correct and write FALSE if the statement is
incorrect.
_______ 1. Temperature is affected by the movement of particles in the environment.
_______ 2. If the molecules vibrate faster the speed of sound in a medium becomes greater.
________3. When the temperature increases, the air molecules move faster so the speed of
           sound is slower.
________ 4. Solid, liquid, and gas are the medium in propagating sound.
________ 5. The factors affecting the speed of sound are density and humidity only.

PERFORMANCE TASKS
Complete the table below by computing the speed of sound in air at different temperature
using the equation below. Show your solutions in each item, you can use the back potion of
this paper. Use the formula below.




Example: Temp is 5 ºC
                           V = 331 m/s + 0.6 m/s (Temperature)
                                              C
                                =331 M/S + 0.6 m/s (5 ºC)
                                                  C
                                    = 331m/s + 3 m/s
                                       V = 334 m/s
       Temperature (in Celsius)                 Speed (in meter per second)
               30 ºC
               40 ºC
