when a cold object is touched state whether the heat energy flows from the person's hand to the object or the object to the person's hand and why is it so?

Heat always flows from hot to cold. Cold is the absence of heat.

What determines whether an object is a net emitter or a net absorber of radiant energy?
magic
What is a cold object?
A cold object is something that when touched, appears to feel cold. Another meaning of a cold object is something that when touched or used to touch something with, may turn that object in question colder or even freeze it.
When you lift an object energy is transferred to an object which gives the object?
When you lift an object, the energy transferred to the object is called gravitational potential energy.
What is a graphic representation that cannot be touched or felt of an object?
A Hologram.
Which element of art refers to the way an object feels or appearances of how an object might feel if touched?
texture
How do you know whether or not an object has energy?
Because it it working and can be turned on and off
Does an object in motion have more energy than on object at rest?
Objects in motion have kinetic energy and objects at rest have potential energy. Whether or not the object in motion has more energy than the same object at rest or vice versa depends on specific circumstances. It depends on the speed of the object in motion.
When you perform work on an object you increase the energy of the object.?
Generally yes, but it really depends on the specific situation. -- If the work is done to lift the object, then the object's potential energy is increased. -- If the work is done to accelerate the object, then the object's kinetic energy is increased. -- If the work is done to move the object against friction, then the energy supplied is dissipated, and the object's energy may or may not change, depending on whether or not it is somewhat heated by the dissipation.

Can the total energy of an object change without any work being done Explain?
Energy is a conserved quantity. That means that, if no energy enters or leaves an object, the total energy of this object will remain the same. There are several ways for energy to enter or leave; I am not sure whether all of these qualify as "work".
Does an electric object break when touched with water?
Not always. It depends on the object.
The energy an object has because of its at rest?
That sounds like a description of potential energy. However, the energy is not BECAUSE the object is at rest; rather, it's energy related to an object's position, with respect to other objects (specifically, if there is some force involved). For example, an object at a height of 100 meters will have a certain amount of gravitational potential energy - regardless of whether it is moving or not.

What determines whether an object is a net absorber or a net emitter of radiant energy at a given time?
All substances above absolute zero emit radiant energy. Whether the object emits more than it absorbs depends on its temperature compared to the temperature of its surroundings. An object warmer than its surroundings will usually be a net emitter.

What is the energy of a moving object called?
The energy of a moving object is called the Vector energy. It is also called Kinetic energy but there is a distinction between Potential energy a real energy and vector energy a vector. it is not clear in physics whether Kinetic energy is a vector or real energy. For example 1/2 mv^2 is called kinetic energy but it is not vector energy.
