<span>A
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:
The SI unit for specific enthalpy is joule per kilogram. It can be expressed in other specific quantities by h = u + pv, where u is the specific internal energy, p is the pressure, and v is specific volume, which is equal to 1ρ, where ρ is the density.
Explanation:
I believe that option C should be correct
The appearance of the protist differ from that of the onion sample due to the presence of motile structures.
<h3>What is a Protist?</h3>
This is an eukaryote which could be unicellular or multicellular and examples include protozoa etc.
The major difference between a protist and onion sample is that protists have motile structures such as flagella, cilia etc while plant cells such as onions don't have.
