What else can I help you with?
The energy transfer in which vibrating molecules pass heat along to other vibrating molecules by direct contact is called?
conduction
What form of energy do molecules possess?
Molecules possess kinetic energy, which is the energy of motion.
The more the molecules an object contain the more heat energy it has?
The heat energy of an object is related to the movement of its molecules, not the number of molecules. Heat energy is determined by the speed and kinetic energy of the molecules, rather than the quantity of molecules in the object.
What is the energy of motion of molecules called?
Kinetic Energy
Explain how water can transfer energy by conduction and by convection?
In conduction, water molecules pass energy through direct contact with neighboring molecules, transferring it without moving the water itself. In convection, energy transfer occurs through the movement of water molecules, as warmer water rises and cooler water sinks, creating a circulation pattern that distributes the energy throughout the water body.
What pigment molecules absorb a photon and pass the energy to the reaction-center complex?
chlorophyll
The energy transfer in which vibrating molecules pass heat along to other vibrating molecules by direct contact is called?
conduction
Can heat pass though bromine?
Yes, heat can pass through bromine since bromine is a liquid at room temperature and is capable of transferring thermal energy. Bromine molecules can vibrate and collide with neighboring molecules to transfer heat as thermal energy.
Is heat conducted better the farther apart the molecules in a substance are?
No, heat is the kinetic energy of molecules, the further apart they are the more difficult it is for them to hit one another so as to pass on the motion energy.
Which phrase best describes the property of selective permeability large molecules pass all ions pass all molecules pass some molecules pass?
The phrase "some molecules pass" best describes the property of selective permeability.
Does heating break up molecules into smaller pieces allowing them to pass easily?
Heating can increase the kinetic energy of molecules, causing them to move more quickly and potentially break apart into smaller pieces. This can make it easier for the molecules to pass through barriers such as cell membranes or chemical reactions.
Why does sunlight energy pass through car windows but the energy radiated from objects inside the car does not?
sunlight passes through exciting the particles in the car warming it up. The heat is then in the air molecules which can't pass through the glass.
What are the three molecules that cannot easily pass through the membrane?
The three molecules that cannot easily pass through the membrane are large molecules, charged molecules, and polar molecules.
Can charged molecules pass through the membrane?
Yes, charged molecules can pass through the membrane.
How do small polar molecules pass through the plasma membrane?
Small polar molecules can pass through the plasma membrane through a process called simple diffusion, where they move from an area of high concentration to low concentration without the need for energy or a transport protein.
What method carries molecules and pump molecules or form channels through which specific molecules pass across the plasma membrane?
Active transport is a method that carries molecules across the plasma membrane against the concentration gradient. This process uses energy, usually in the form of ATP, to pump molecules or form channels through which specific molecules can pass. Examples include the sodium-potassium pump and ion channels.
What form of energy do molecules possess?
Molecules possess kinetic energy, which is the energy of motion.
