The molecules in object a possess a higher average kinetic energy than those in object b. thus:
heat could transfer from object b to object a.
heat could transfer from object a to object b.
the molecules in object a are vibrating less than in object b.
the temperature of object b is higher than object a.

2nd option

Heat could transfer from object A to B

The reason : higher kinetic energy means the particles in A are moving /vibrating faster. This is a reason due to hight temperature.

Option (b) is the correct answer.

Explanation:

When two objects of different temperature are kept in contact with each other then exchange of heat energy will take place between the two objects until a dynamic equilibrium is reached between the two object.

So, heat will transfer from a hooter object to a colder object.

For example, when molecules in object A possess a higher average kinetic energy than those in object B, then heat will be transferred from object A to object B.

Thus, we can conclude that in the given situation heat could transfer from object A to object B.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
