What kind of heat transfer can happen between objects where there are no molecules?
Radiative heat transfer can occur between objects where there are no molecules. This type of heat transfer does not rely on the presence of a medium for energy transfer, as it involves the emission and absorption of electromagnetic radiation between objects at different temperatures.

What is transfer of electric charge between object?
Transfer of electric charge between objects refers to the movement of electrons from one object to another. This can happen through processes like conduction (direct contact between objects), induction (caused by the presence of a charged object nearby), or friction (rubbing objects together to transfer charge). This transfer of charge causes objects to become positively or negatively charged.
could conduction happen between two objects that were not touching?
No, conduction requires physical contact between objects to transfer heat. Without direct contact, conduction cannot occur.
What transfer of energy naturally occurs between objects?
If two objects of different temperature are brought into contact, internal energy is transferred via heat. If two objects collide, kinetic energy is transferred between them.
What are 2 ways for conduction to take place?
Conduction can occur through direct contact between objects of different temperatures, where heat is transferred from the warmer object to the cooler object. It can also happen in solids, where vibrating molecules pass on kinetic energy to neighboring molecules.
How is energy transferred from warmer objects to cooler objects?
Energy is transferred from warmer objects to cooler objects through a process called heat transfer. This can happen through conduction, where heat is transferred through direct contact between the objects, convection, where heat is transferred through the movement of fluids like air or water, and radiation, where heat is transferred through electromagnetic waves.
Can energy transfer happen between two objects when each object has the exact same energy?
When each object has the same energy, energy transfer can still occur between objects. The object with the greatest mass or traveling speed will transfer the energy.

What must happen or heat to be tranferred by thermal conduction?
In order for heat to be transferred by thermal conduction, there must be a temperature difference between two objects or regions. Heat will naturally flow from the warmer object to the cooler object until both reach thermal equilibrium. This transfer occurs through direct physical contact and the vibration of atoms and molecules.
Why heat transfer happen?
heat transfer happens because objects that have energy, meaning vibrating atoms will bump against others and transfer the energy to the other atoms and so on. and also because things always have a tendency to have more entropy as time passes.
How is the activation energy related to whether or not collision between molecules is successful?
Generally speaking, the lower the activation energy, the more successful collision between molecules will happen.
What must happen for heat the be transferred by thermal conduction?
For heat to be transferred by thermal conduction, there must be a temperature difference between two objects or substances in contact. Heat energy will naturally flow from the warmer object to the cooler object until they reach thermal equilibrium. This transfer occurs through the vibration and collision of atoms and molecules in a solid, which carries thermal energy through the material.
Why do forces happen?
Forces occur due to interactions between objects. They can result from contact between objects (contact forces) or from the attraction or repulsion between objects without direct contact (field forces such as gravity or magnetism). Forces cause objects to accelerate, decelerate, or change direction.
What would happen to the force of gravity between 2 objects if their masses remained constant but their distance between them decreased?
The force of gravity between two objects will increase if their distances decrease. The force of gravity or proportional to the objects' masses, and inversely proportional to the square of the distance between them.
