Dan got into his car in the middle of summer. When he sat on the hot black leather seats, he burned his legs. His sister said th
LekaFEV [45]

The correct answer is D) Dan's sister was correct because Dan's legs touched the car seats. That is an indicator of heat transfer by conduction.

Conduction only happens when a heated object touches a non-heated (or not as heated) object. Radiation did cause the car to become hot, but conduction caused Dan to get burned.

Hope this helps!! :D

guapka [62]

Answer : The correct option is, (b) occur when there is more free energy in the reactants than the products.

Explanation :

Endergonic reactions : It i defined as the reaction in which the energy is absorbed during the reaction.

In endergonic reactions, the Gibbs free energy of product is lower than the reactants. That means, ΔG > 0 and the reaction is non-spontaneous.

Exergonic reactions : It i defined as the reaction in which the energy is released during the reaction.

In exergonic reactions, the Gibbs free energy of product is greater than the reactants. That means, ΔG < 0 and the reaction is spontaneous.

Hence, the endergonic reactions is occur when there is more free energy in the reactants than the products.
