Which sentence in the passage can be used to conclude that eris is a dwarf planet and not a planet?
eris takes about 557 earth years to orbit the sun. it has a mean surface temperature of about 40 kelvin. it has a nearly spherical shape. it has several other objects in its orbit, though few are as massive as itself. eris is too far away and small to be clearly visible from the earth. scientists used its moon, dysnomia, to measure it. eris is believed to be slightly more massive than pluto. however, both of them are smaller than earth’s moon. eris orbits the sun directly; it is not a satellite of another planet or dwarf planet.

It has several other objects in its orbit , though few are as massive as itself.

Explanation:

A celestial body orbiting the sun is considered  a planet when its mass is more than sum of  all other celestial  bodies moving along with it in its orbit round the sun.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
