What is the energy that flows from a warmer body to a colder body?
No, thermal energy always transfers from a relatively hot object to a relatively cold object. This is because, when heated, atoms have more kinetic energy, and they pass this down to the "colder" particles, which have a lesser degree of kinetic energy.
Is heat energy transferred from a warmer object to a cooler object?
No, heat ALWAYS travels from hot to cold. It is not actual heat moving, it is energy. The more energy something has, the warmer it feels. For example, when you touch a metal railing on a winter day, it feels cold. That is because your hand has more energy than the rail. The energy from your hand is traveling into the railing to equalize the energy (moving towards equilibrium. The loss of energy in your hand is what gives you the "cold" feeling. Heat/energy NEVER moves from cold to hot.
When does an object have more thermal energy when it is hot or cold?
Hot.
How do you know how hot an object is?
Heat is a form of energy. The energy is tied to the molecules of the object. The faster the molecules in an object vibrate, the more heat energy it contains and therefore the more hotter it is. By measuring the amount of vibration in an objects molecules, you can calculate how hot it is.
What is the difference between temerature and heat?
Heat is the total number of molecular energy in motion in an object meaning the more hotter an object is the molecular energy moves faster. While temperature is simply the measurement of heat or thermal energy on a certain object.

Why is cold just the absence of heat?
"Cold" is a relative term, like "high" or "fast". It does exist as a qualitative term but only for comparison. It doesn't exist as a concrete object.
Why do cold objects have heat energy?
A warm object has more energy that a cold object and we call that heat energy. More heat energy corresponds to more energy of the constituent particles (atoms and molecules.) The energy of constituent particles is both kinetic and potential. Boltzmann was a physicist studying heat and thermodynamics about 150 years ago and we know from his work that the temperature of a system is proportional to the average kinetic energy of the particles in the system. It is thus correct to say that warm objects have particles with more kinetic energy. (We more often say that the warm object has more heat energy energy because the heat energy accounts for both increased potential energy of molecules and thier increased kinetic energy.)

How does temperature increase or decrease?
Temperature is the average Kinetic energy of molecules in an object. A hot object has more kinetic energy and a cold object has less kinetic energy.
Can an object gain more energy?
Sure, you can add energy to an object. For example, you can heat an object up (to have it gain heat energy), you can raise it (to have it gain gravitational potential energy), or you can make it move (to have it gain kinetic energy). In each case, the energy has to come from somewhere.
Energy of hot objects?
energy is heat so more than cold objects
When an object falls and touches ground the kinetic energy transforms to which energy?
Heat, sound and more kinetic energy as things are moved by the impact of the object.
What is relation between temperature and molecular vibration of an object?
Heat energy in a substance is the intensity of vibration of the molecules in that substance. The more the vibration more is the heat energy stored in the object. So in a way Heat energy is the kinetic energy of the molecules in the substance. Thus temperature increases on the increase in the kinetic energy of the gases.
