Gases can be easily compressed.
They do not have a shape or definite volume.
So, a is correct and c is wrong.
Liquid have definite volume but not shape.
So, they take shape of container.
So, b is correct.
Melting: The process in which solid changes to liquid
Vapourisation: The process in which liquid changes to gas
Sublimation: The process in which solid changes to gas
Fusion: The process in which liquid changes to solid
Condensation: The process in which gas changes to liquid
deposition: The process in which gas changes to solid
So, d is correct
Answer: c
which statement is incorrect concerning differences of gases, liquids and solids? a) gases are easily compressed...
What are the main properties of liquids (in contrast to gases and solids)? Check all that apply. Liquids have an indefinite shape and assume the shape of their container. Liquids have much higher densities in comparison to gases. Liquids are not easily compressed. Liquids have an indefinite shape and do not assume the shape of their container. Liquids are easily compressed. Liquids have not a definite volume. Liquids have a definite volume. Liquids have lower densities in comparison to gases.
What are the differences between liquids and solids? b. What are the differences between liquids and gases? Define briefly: boiling point melting point What is the difference between a nomadic liquid crystal and a sematic A liquid crystal? Ethanol (C_2H_5OH) Delta H_vap =38.56 kJ/mol. Delta H_fus= 5.02kJ/mol, Boiling point = 78degree C, melting point = -114 degree C Specific heat of solid ethanol = 0.97J/g-K, specific heat of liquid ethanol = 2.3J/g-K How much heat does it take to convert...

All are the same #2) Which physical property/state is incorrectly matched? a. liquids - rigid shape b. gases - easily compressed c. gases and liquids - flow d. solids - higher density than gases e. liquids - incompressible
Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average pressure is 1 atm. As you...
17. When a liquid sample is taken from sea level to a higher elevation, what happens to the external (atmospheric) pressure on the liquid and the boiling point of the liquid? A) Both decrease. B) Both increase. C) Pressure goes down but boiling point goes up D) Pressure goes up but boiling point goes down. 18. In comparing gases with liquids, gases have A) greater; smaller B) greater; greater C) smaller; smaller D) smaller; greater E) none of the above...
