Which statement gives the main idea of the kinetic theory of heat?

When objects are heated, particles slow down.

Colder objects emit more radiation than hotter ones.

Heat flows from warmer to colder objects.

Heat is transferred by the interaction of moving particles.

The best option is "Heat is transferred by the interaction of moving particles."

Explanation:

The Kinetic Molecular Theory of Heat states that molecules in a fluid increase their speed as temperature increases.

Kinetic theory of heat is a theory that the temperature of a body is determined by the average kinetic energy of its particles and that an inflow of heat increases this energy.

Heat and temperature are related to each other, but are different concepts.

1. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance.

2. Temperature does not depend on the size or type of object.

Also heat can be transferred but temperature can't be transferred.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

58750.08068 is the answer i think
