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

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

is there any options? maybe im just not seeing them but i need the options to
