In the above picture, suppose the rod were made of solid glass instead of solid aluminium. Which statement is correct?
Glass is a good conductor so glog A melts faster
Glass has particles that can flow, so the wax melts by convection
Glass is a good insula on to the wax would not melt
Glass allows radiation to pass though it so the wax would melt slower

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.

the answer is the first option

explanation:

just googled it m8. not that hard
