At 25°c, the screech of the sneetches can travel 250 meters across the plains of sneedville in 0.50 seconds. determine the velocity of these sound waves as they travel across the plains. show your work

The velocity of the sound waves across the plains of Sneedville is 500 m/s.

Step-by-Step Explanation:

Distance travel by the screech of Sneetches = d = 250 m

Time taken to cove 250 meters = t = 0.50 s

Let the velocity of the sound waves be v, such that:

v = d/t

⇒ v = 250/0.5

⇒ v = 500 m/s

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
