The variables for part ii of this experiment include the type of material used and the thermal energy transferred by that material. use the drop-down menus to complete the sentences and identify the independent and dependent variables. the independent variable, the one that is intentionally manipulated, is the . the dependent variable, the one that you measure the response in, is the .

The passage that directs air to the lungs is called a. diaphragm. b. larynx. c. bronchi. d. pharynx.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

What is the rate of change in a objects position?
