As an object becomes hotter, the rate of heat transfer from the object to a cooler body with which it is in contact would

a. decrease
b. increase
c. not change
d. no determination can be made from the information given

b. increase

Explanation:

According to fourier's law of conduction the rate of transfer of heat from a hot body to cold body is directly proportional to the temperature difference of the bodies

L= length of the object

A= area of contact

ΔT= temperature difference

k= thermal conductivity.

therefore we can say that As an object becomes hotter, the rate of heat transfer from the object to a cooler body with which it is in contact would

b. increase

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

explanation:

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
