Are beverages usually acidic or basic? why is this?

ACIDIC

Explanation:

Usually beverages contain carbonated water. Carbonated water is the water containing dissolved carbon dioxide gas.

The carbon dioxide gas (CO₂) when dissolved in water produces carbonic acid (H₂CO₃), which makes the drinks acidic in nature.

H₂O(l) + CO₂(g) → H₂CO₃(aq)

This makes the pH of the drinks around 3 - 4.

Therefore, the beverages are usually acidic and not basic.

B) The energy of the solid increases, and the particles begin to slide past each other.

Explanation:

The energy of the solid matter is required to be increased so that molecules of the solid matter get separated from each other and an transition from solid matter to liquid matter occurs. The liquid components of the matter will slide past each other as they have obtain energy for fluidity. The liquid iron can be molded into any shape and the energy decreases considerably.
