Answer:
Specific heat: = energy required to change a unit mass of a material by 1°C. Units: energy per unit mass per degree.
Latent heat = energy required to change the state (gas, liquid, solid) of a unit mass of material. Units: energy per unit mass.
Explanation:
Answer:
B - False
Explanation: a dispersed formation means spreading out, more like an attacking or advancing position. This doesn't depict a defensive measure.
<em><u>Answer:</u></em>
Solids
<em><u>Explanation:</u></em>
<u>Solids</u> have definite shapes and definite volumes. The forces of attraction between the molecules of a solid substance are strong and the intermolecular spaces are very small. Due to this, the motion of molecules within a solid substance are very difficult that they only vibrate in their positions.
<u>For liquids</u>, they have definite volumes and indefinite shapes. The forces of attraction between the molecules of a liquid are intermediate and the the intermolecular spaces are intermediate as well. Due to this, the motion of molecules within a liquid substance is not as difficult as it is within solids.
Finally, <u>for gases</u>, they have indefinite shapes and indefinite volumes. The forces of attraction between the molecules of a gas are weak and the intermolecular spaces are large. Due to this, the motion of particles of gas is very easy.

The correct formula for calculating the tangential speed of an orbiting object is V(t)=wr.
V(t)= Tangential Speed
w= Angular Velocity
r= Radius of the Path
Hope this helps.
