Two samples of carbon come into contact. A heat transfer will occur between sample A and sample B. What must be true for heat to
jarptica [38.1K]

Answer:

The average kinetic energy of A is greater than that of B.

Explanation:

The temperature of an object is directly proportional to the average kinetic energy of the particles in the object. For instance, for an ideal gas, we have

KE=\frac{3}{2}kT

where

KE is the kinetic energy

k is the Boltzmann constant

T the absolute temperature of the gas

Therefore, this means that in a hotter object the average kinetic energy of the particles is higher than the average kinetic energy of the particles in a colder object.

Moreover, the laws of thermodynamics tell us that heat is always transferred from a hotter object (higher temperature) to a colder object (lower temperature).

In this problem heat is transferred from sample A to sample B. Therefore, this means that object A has higher temperature, and therefore, higher average kinetic energy. So the correct answer is

The average kinetic energy of A is greater than that of B.

Why is a solution not a pure substance?
Kaylis [27]

A solution is not a pure substance as it is a mixture between a solute and a solvent.

Pure substances are substances that are made up of only type of particles and have a fixed structure. In pure substances the matter cannot be separated into other kinds of matter by any physical means.

A homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility. The term solution is commonly applied to the liquid state of matter, but solutions of gases and solids are possible.

A solution cannot be a pure substance because it is made up of a homogenous mixture of solute and a solvent. Homogenous means the matter cannot be separated out and therefore a solution cannot be a pure substance.

What do organisms have based on their functions?
mote1985 [20]
Unicellular organisms, cells perform all the basic actions and functions required for living like nutrition, respiration, reproduction etc.

In multicellular organisms, cells divide their tasks on the basis of "DIVISION OF LABOUR" to specialize in certain functions besides respiration etc. Like conduction in neurons, excitation in muscles, RBC production by bone marrow etc.
