Question 18 The picture below shows a model of a weather instrument made with simple objects. Stopper Clear Plastic Soda Straw Glass Bottle Colored Water The change in the height of water in the straw of the model instrument is noted at regular intervals of time. Which of these best describes the function of the model instrument? (1 point) To increase the humidity of air by changing water to vapor. o To reduce the temperature by increasing the moisture in alr. To predict storms by measuring the atmospheric pressure To measure the amount of rainfall by collecting water in the straw.

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.

answer: what are you talking about?

explanation:

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
