The thermometers show the variation in temperatures of a rod at different points. What process of heat transfer causes this variation? conduction convection emission radiation

conduction

Explanation:

Heat conduction is the transfer of internal thermal energy by the collisions of microscopic particles and movement of electrons within a body. The microscopic particles in the heat conduction can be molecules, atoms, and electrons(Science direct).

From the statement above, heat is transferred via conduction when the particles in a body collide with each other. The heat energy gradually travels through the entire length of the material(initially found to exhibit variation in temperature with length) causing an increase in temperature starting at the part of the rod directly exposed to the heat source until the temperature becomes uniform throughout the rod.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
