Question

how can we protect pups paws?

1. when two objects are in contact, thermal energy will transfer

from the warmer object to the cooler object
back and forth between the two objects
only if the objects are made of the same material
from the cooler object to the warmer object
the dog in the gif above is wearing boots! while this may look silly and cute, boots like

Explanation:

Thermal energy transfer occurs due to a temperature difference. The second law of thermodynamics states that heat (thermal energy) flows spontaneously from a warmer object to a cooler one until thermal equilibrium is reached. It does not transfer back and forth in a net sense (there is random molecular motion, but net transfer is one - way). Also, material composition is not a requirement for heat transfer (as long as there is a temperature difference).

Answer:

from the warmer object to the cooler object
