Use what you learned from the PhET Simulation on the Properties of Gases and from the 3.04 Gas Laws lab to answer the following question. Write a paragraph!
Scenario (not a real experiment). Start with a balloon at room temperature, measure the diameter
Then put it into hot water and measure the diameter. Then put it into ice water and measure the
diameter
Explain why a balloon in hot water expands but a balloon in ice water shrinks. Be sure to
include the following information
(1) the number of molecules
(2) the temperature
(3) energy of the molecules
(4y the pressure
(5) the volume

During takeoff, the sound intensity level of a jet engine is 170db at a distance of 34 m. what's the sound intensity level at a distance of 1.0 km?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 2 options: the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the cold balloon expands and rises. the warm balloon shrinks and sinks. the warm balloon expands and rises. the cold balloon shrinks and sinks.
