Alex heated some water in a pan until the entire water changed into vapor. The mass of the total vapor formed was 150 g. What was most likely the mass of the water Alex heated and why? (1 point) 175 g, water vapor formed is lighter than water

150 g, mass of the water remains the same when it changes state

175 g, some water molecules are destroyed during phase change

150 g, mass remains same during chemical change of water into vapor

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels. the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause, directly and indirectly, for such a rise in sea level is
