substance can absorb or release heat energy by the process of radiation,
convection, or conduction. Radiation refers to the transfer of energy through emission
of electromagnetic waves or the movement of particles. An example of radiation
is the Sun’s rays. This type of heat transfer does not require direct contact between
objects. Convection, on the other hand, involves the hotter fluid rising while
the colder fluid sinks. Convection occurs when you boil water in a pan. Lastly,
conduction is a heat transfer that occurs as a result of temperature difference
between two objects in contact. Heat is transferred from the hotter region to
the colder region. Conduction occurs when ice melts in your hands. </span>
Answer:
I don't not it is answer.
Answer:
option C
Explanation:
Metallic bonds exist in the atoms of metals. mobile electrons exist in metallic bonds and are referred as electron sea.This is the property that makes metals to have a high electrical conductivity.
Electrovalent and ionic bonds are formed when a metal loses an electron to a nonmetal. covalent bonds exists when electrons are shared between molecules of same elements or of different elements.
Answer: Sublimation
Explanation: The process of a solid becoming a gas is called sublimation.
