1. Identify each of the following changes as endothermic, exothermic, or not possible to tell. The matter to keep in perspective is in italics in each case. Explain your decision in each case. a) When effervescent antacid tablets are dropped into water, the tablets slowly disappear and the water becomes fizzy. b) On a hot day, water vapor condenses out of the air and turns into liquid droplets on the outside of a cold glass of lemonade. c) The copper on the Statue of Liberty oxidizes and turns blue.

When effervescent antacid tablets are dropped into water, the tablets slowly disappear and the water becomes fizzy- endothermic

On a hot day, water vapor condenses out of the air and turns into liquid droplets on the outside of a cold glass of lemonade- exothermic

The copper on the Statue of Liberty oxidizes and turns blue.- endothermic

Explanation:

An exothermic reaction is a reaction in which heat is given out to the surrounding. The temperature of the system increases when an exothermic reaction occurs. An endothermic reaction occurs when heat is absorbed and the temperature of the system decreases. Oxidation of elements and effervescence of antacid solution are endothermic processes.

Given that the water vapour in air losses energy upon condensation to liquid, the process is exothermic

that's just how they are

explanation:

you can't control another persons decisions, all you can do is ask that they respect yours. relationships are hard because you have to put the effort into making sure that another person feels seen, heard, and loved. as time goes on, it gets easier, you learn how to do these things without thinking. loving them becomes as easy as breathing, but every relationship will have fights, and sometimes it'll feel like you're drowning, but as long as you can talk it out and compromise, because that's truly what loving another person is, is compromise, then you'll be okay. movies and tv shows have glamorized and romanticized (pardon the pun) what a relationship would be like. real relationships aren't perfectly timed kisses in the rain, zero fights until one big one ends everything, 6 month anniversaries. real relationships are sleepy confused kisses when one person has to leave for work earlier than the other,   real relationships are having small disagreements, real relationships are messy and confusing, real relationships is knowing that even if you're relationship may not last forever and this may not be the person you're going to spend the rest of your life with, that you love them, and you would do anything to see them happy. so yes, relationships are difficult, but so are many other things, relationships can be amazing but also stressful, and not just romantic i'm also talking about platonic relationships (although the primary example here was romantic) sometimes is best to leave friendships behind, so remember, always do whats going to you be happy in the long run.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
