• decrease

• stay the same

When comparing sound traveling through the air, I can tell from the chart, it travels faster at 1,127 ft/sec because...

• the temperature is 68 degrees, which means the molecules are able to transfer the waves faster.

• the temperature is 32 degrees, which means the molecules are able to transfer the waves faster.

• the temperature is always the same for air, so the temperature does not make a difference

• air is a gas that is spread out and allows the sound waves to travel through it faster

Steel is a very dense solid, but when I compare the steel at 32 degrees, I see that it travels a little slower than the steel at 68 degrees.

• Heat has no effect on how fast or slow molecules move.

• This is true because the heat causes the molecules to vibrate a bit slower.

• This is true because the heat causes the molecules to stay still a bit longer.

• This is true because the heat causes the molecules to vibrate a bit faster.

Air has more molecules than the glass, therefore, light will travel slower in the air than in the glass.
