This is a poorly stated question.
What do you mean by size? Volume or mass?
By your question, if all other factors are constant, increasing the size, (whatever you mean by that) will have no effect.
If you mean that you have a mass at a certain temperature and you double the mass at that temperature, then the total energy doubles.
Yes
yes-increase its mass
yes
TRUE
the movement of energy from a warmer object to a cooler object is called heat transfer
Heat is thermal energy moving from a warmer object to a cooler object.
raising of object temperature, the mass, specific heat
Increasing temperature means increased kinetic energy on the atomic or molecular level. Temperature of a given substance is the average kinetic energy of the particles of which that substance is composed.
No, an object will not be a net radiator of energy when its thermal energy is less than that of its surroundings. In this case, the object will instead absorb thermal energy from its surroundings in an attempt to reach thermal equilibrium.
Yes, the hotter an object is, the greater the thermal energy it has.
"Thermal energy" or "heat"."Thermal energy" or "heat"."Thermal energy" or "heat"."Thermal energy" or "heat".
Increasing the speed will increase the KINETIC energy, not the potential energy. Of course, the potential energy may eventually be converted into kinetic energy, for example if the object moves upwards.
