A meteorologist detects a decrease in air pressure as warm, moist air rises over cold air. What type of weather is most likely to result? A: Heavy rainstorms, followed by light rain
B: Alternating snowfall and sunshine
C: Hot and dry conditions, followed by thunderstorms
D: Cool and cloudy conditions, without change

Pls don't give wrong answers on purpose​

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
