How would the volume of helium in a balloon be affected if the balloon was placed in a room where air temperature is lower? a. increase b. decrease c. no change

the correct answer is B. decrease

Explanation: When a balloon is placed in a room where air temperature is lower and the pressure is constant the volume decreases.

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'm assuming that the correct answer is indeed the first one/ "a"..
