Can THC be transferred to someone through contact with their skin saliva or body fluids?
No
What is the dispersion of molecules of one substance through the body of another?
absorption ... dobbielind :) thats my answer.
What describes how an atom becomes negatively charged?
electrons are transferred to the atom from other atoms through direct contact
If you have a mixture of substances with different - sized molecules. How could you separate them?
pour the mixture through a filter that will let the smaller substance through, but not the larger one.
What is the diffrence between osmosis and diffusion?
Diffusion is the spreading of a substance in another substance effected by the thermal movements of the molecules or other forces acting between the molecules. The spreading happens from an area with high density into areas with originally lower density. For osmosis to occur you must have a solvent in two rooms separated by a membran that lets the solvent molecules pass. In one of the rooms there is a dissolved substance that cannot pass the membrane in a higher concentration than in the other room. This makes solvent pass over to the room with the highest concentration of the substance so that the pressure gets higher in that room and the solution gets less concentrated. The process stops when the pressure is high enough or the concentration of the dissolved substance is equal in both rooms. The mechanism behind osmosis is as follows: The solvent molecules are always moving because of their termal kinetic energy and are steadily colliding with each other and also with molecules of the dissolved substance. All the time some solvent molecules pass through the membran between the two rooms also, and in both directions. But the dissolved substance will all the time collide with some of the solvent molecules and block their passage through the membran. Solvent molecules in the room with most dissolved substance will however be blocked more often from passing than solvent molecules in the other room. Thus there will be most passings from the room with the least dissolved substance.
How is heat transferred through conduction?
Heat is transferred through contact between molecules.
How is heat transferred through thermal conductions?
Heat is transferred through contact between molecules.
Is heat transferred through thermal conduction?
Heat is transferred through contact between molecules.
Why does heat go from a hot place to a colder place?
For simplicity, assume two solid blocks of the same material. Molecules in the hotter substance move faster on average; they will bounce against the molecules in the colder substance, transferring part of their energy. Energy is also transferred through bounces from the cold substance to the hot substance - but on average, more energy will be transferred from the hot to the cold substance, simply because on average, the molecules move faster.
A coin is placed on a very hot rock. How will most of the heat be transferred to the coin?
Molecules in the rock will transfer heat to molecules in the coin through direct contact.

The transfer of energy as heat through a substance by direct contact?
Conduction is where heat energy pass though the molecules by direct contact
How is earth atmosphere warmed evenly?
Energy is transferred between the earths surface and the atmosphere via conduction, convection, and radiation. Conduction is the process by which heat energy is transmitted through contact with neighboring molecules.
What is the driving potential for heat transfer?
The driving potential for heat transfer is the temperature difference between two systems. Heat will naturally flow from a higher temperature to a lower temperature in order to reach thermal equilibrium.
Which type of heat transfer is it when heat is transferred through a substance?
Conduction.
What is the transfer of energy when molecules bump into each other through contact?
The energy that is transferred when molecules bump into each other is called conduction. Conduction is the transfer of heat energy between substances that are in direct contact with each other.
Transfer of thermal energy of a hotter object to any cooler one is?
known as heat transfer, which occurs through three main mechanisms: conduction, convection, and radiation. In conduction, heat is transferred through direct contact between molecules. In convection, heat is transferred through the movement of a fluid. In radiation, heat is transferred through electromagnetic waves.
