Which of the following statements accurately describes the properties of gases? A. Gases expand very easily due to a property called compressibility.

B. A change in the pressure of a gas results in a more significant change in volume than it would in a liquid.

C. Applying an external force to an enclosed volume of air will allow the air to expand and the volume to decrease.

D. When the mass of gases remains constant, the gases have low compressibility and low expansibility.

Answer 1
Answer: A change in the pressure of a gas results in a more significant change in volume than it would in a liquid.  is the statement that accurately describes the property of gas. Gas only depends on how you store it. the bigger the space the wider gas can expand, the smaller the space, the more compress the gas can become.

When you approach a light source, the wavelength of emitted light appears _____.a. shorter
b. the same
c. longer

Answers

When you approach a light source, or when the light source
approaches you, the wavelength of the light you see is shorter
than the wavelength of the light that's actually emitted by the source.

Similarly, when you approach a sound source, or when the sound
source approaches you, the wavelength of the sound you hear is
shorter than the wavelength of the sound that's actually emitted by
the source. 

Answer:

A. shorter
