The heat energy radiated by a body increases with the temperature raised to the fourth power according to the Stefan-Boltzmann law. This means that as the temperature of a body increases, the amount of heat energy radiated also increases significantly.
Temperature is the measure of heat in a body, as measured by the motion of its molecules. As you are providing heat energy to the body, the molecules of the body gain kinetic energy (due to the principle of conservation of heat). Hence the temperature increases unless it is transferred or radiated elsewhere.
Steven's law of radiation states that the total energy radiated per unit surface area of a black body is directly proportional to the fourth power of the body's absolute temperature, as expressed by the equation E = σT⁴. This law quantitatively relates the amount of energy emitted by an object to its temperature.

The kinetic energy of a body depends on its mass and its velocity. As the mass of the body increases, its kinetic energy also increases. Similarly, as the velocity of the body increases, its kinetic energy increases as well.
No, the temperature of a body does not depend on the frame from which it is observed. Temperature is an intrinsic property of an object that does not change based on the observer's frame of reference.

Emissive power is defined as the energy radiated from a body per unit area per unit time at any given temperature.

The term "emissivity" refers to the relative power of a surface to emit heat by radiation. It could also be defined as the ratio of energy radiated by a particular material to energy radiated by a black body.

The laws of radiant energy refer to principles related to the behavior and interaction of electromagnetic radiation. These laws include the Stefan-Boltzmann law, which describes how the total energy radiated by a black body is proportional to the fourth power of its temperature, and Wien's displacement law, which establishes the relationship between the temperature of a black body radiator and the dominant wavelength of the emitted radiation. Additionally, Planck's law describes the spectral distribution of energy emitted by a black body at a given temperature.

True. Your body maintains its temperature through a process called thermoregulation, in which chemical energy from the food you eat is converted into thermal energy to help regulate your body temperature.
No, the temperature of a body does not depend on the frame from which it is observed. Temperature is an intrinsic property of an object that does not change based on the observer's frame of reference.
The amount of heat radiated by a body depends on factors such as its temperature, surface area, and emissivity. Higher temperatures, larger surface areas, and higher emissivity values generally result in greater heat radiation.
It is true that to maintain your body temperature, your body converts chemical potential energy into thermal energy. Thermal energy is energy that comes from heat.
