The particles of a gas inside a balloon are experiencing an increase in the average kinetic energy and the number of collisions
with the wall of the baloon. What is the most likely outcome?
1. higher gas pressure inside the balloon

2.higher ar pressure outside the balloon

3. a decrease in gas temperature inside the baloon

4. a large increase in ar temperature outside the balloon

Jessica is traveling from miami, florida, to chicago, illinois. using the map, tell one way the land will change during the second half of her trip.

Particles vibrate in a rigid structure and do not move relative to their neighbors.

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.
