What happen to the force of gravity between two objects when the mass of one of the objects is increased?
Force of gravity also increases proportionally.
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.
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.
What stops heat transfer?
If heat is being transferred by conduction, separating the two objects will stop heat transfer by that means.If heat transfer is by convection, stopping the flow of fluid between two objects will eliminate that means of heat transfer. One notable way of doing that is to interpose a vacuum between the two objects.If heat transfer is by radiation, the energy has to be sent out by the source and absorbed by the sink without interruption. If that can be interrupted then that can't happen. Some ways of achieving this areplace a non-transparent barrier between the source and sink - of course if the barrier absorbs the heat and then re-radiates it out the other side you still have heat transfermake the surface of the sink perfectly reflective - in which case no energy would be absorbed and thus no heat transfer would occur. Note that getting perfect reflectivity is impossible as far as we know.separate the source and the sink an infinite distance such that attenuation of the transmitted energy would reduce it to zero. Of course we don't have infinite distance to work with so that will only work for a thought experiment.Of course in all cases if the temperatures of two objects are the same, no heat transfer will occur no matter what mode of heat transfer you are considering.
What will happen to moving objects if there is no friction?
There is no motion
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.
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 happen to the force of gravity between two objects when the mass of one of the objects is increased?
Force of gravity also increases proportionally.
Where the energy transfer happen when earth matieral increases in temperature when put under a lamp?
Energy is transferred from the photons in the light to the molecules of the earth material.
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.

What happens when there is a temperature difference between two object?
Temperature is a measure of the heat energy of objects, and heat is the energy transferred from a high temperature location to a low temperature location.When two objects are in contact, heat always flows from the warmer object to the cooler object by conduction, until thermal equilibrium is established and the heat transfer stops (becomes the same in either direction). The transfer of heat continues as long as there is a difference in temperature between the two points.
What will happen if the the same charged object come together?
The electrostatic forces between two objects that have the same kind of charge act in the direction to push the objects apart.
Are most chemical changes seen or not seen?
Most chemical changes happen between molecules, so they are unseen.
What would first happen to DNA molecules treated with DNAase?
The phosphodiester bonds between deoxyribose sugars would be broken
What happen to the ices molecules during this phase change?
The ice (solid) become water (liquid); the distances between molecules are decreased during the change of phase, also the attraction forces.
What would happen if glycolsis did not happen in a cell?
If glycolysis could not happen in a cell, the cell would not produce ATP molecules.
