Answer:
Steam because steam pushes out and ice stays dormant.
Explanation:
The height of the described cylinder is 0.85 cm
Mass= 98g
Density= 8.9g/cm^3
Density= (mass/volume)
Substitute the values
8.94= 98/ volume
Volume= 
Volume= 10.97
Volume of a cylinder can be found with (V = π r 2 h.)
h= height of cylinder ?
radius= 2cm
Substitute the values
10.97= π × 
× h
h= 10.97/12.57
h= 0.85 cm
Therefore, height of the described cylinder is 0.85 cm

Answer:
B. Mechanical waves must travel through a medium, but electromagnetic waves do not require a medium.
Explanation:
A wave is defined as any disturbance that transmits energy from one point to another.
Waves can be typically classified as either mechanical or electromagnetic waves.
Mechanical waves are waves that requires a medium for their propagation. In a vacuum, they cannot be propagated and would not cause any disturbance. An example is sound waves.
Electromagnetic waves do not require a medium to be propagated. They can pass through any substance in nature. Electromagnetic radiations belongs to this class.
Answer:
When the kinetic energy of water vapor decreases during condensation, <u>slowly moving particles near the cool surface condense.</u>
Explanation:
The change of state from a gas to a liquid is condensation. Liquid molecules which have this certain kinetic energy threshold escape from the surface and become vapor. As a result, the remaining liquid molecules now have lower kinetic energy. The temperature of the remaining liquid decreases as evaporation occurs.
The air that surrounded it cooled the cold can or glass. When you're cooling off .They lose kinetic energy, a gas. The particles move more slowly as they move, the attractions between them cause the formation of droplets of liquid. Condensed With, when hot air containing water vapor reaches water, water also forms. Cold surface touch, such as a glass of ice or soil that has a cold surface refrigerated throughout the night.
I believe the molecular geometry of PCL3 would be trigonal planar.
