For every iron there are 3 chlorine.
A. Its temperature will rise continuously until it completely melts
I don't believe that any of the other answers are correct because the ice cannot stay at a certain temperature if it is melting.
Answer:
a. Thermal energy in transit due to spatial temperature difference .
Explanation:
Heat transfer -
Heat transfer is the exchange of the thermal energy or heat in between any physical systems .
It is the flow of energy or any form of energy from one system to another .
Heat transfer is divided into various mechanism , one of which is the thermal .
The thermal energy is the transit due to the spacial temperature difference .
The answer is: A molecule with a difference in electrical charge between two ends.
Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.
Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
For example fluorine has electronegativity approximately χ = 4 and oxygen χ = 3,5, fluorine attracts electron and he has negative charge and oxygen has positive charge.
