Most (60%) of the energy we use in our metabolism is lost as heat energy.
The process of evaporation helps cool your body when it sweats. As sweat evaporates from your skin, it takes heat with it, helping to lower your body temperature.
Sweating cools the body by evaporating off the skin, which helps to dissipate heat and lower body temperature.
The heat that warms your body comes from the energy produced by your body's cells during metabolism. This heat helps to maintain your body temperature by keeping it within a narrow range that is necessary for your body to function properly.
The muscular system produces heat in the body through the process of muscle contractions. When muscles contract, they generate heat as a byproduct of the energy used during the contraction. This heat helps to regulate body temperature and keep the body warm.
The body loses heat through radiation, conduction, convection, and evaporation. Radiation is heat loss through electromagnetic waves, conduction is through direct contact with a cooler surface, convection is through air currents carrying away heat, and evaporation is when sweat on the skin evaporates taking heat with it.
The amount of heat given off by the body can be measured using a thermometer or a calorimeter. Skin temperature can be measured using a skin thermometer placed on the body, while the total heat production can be estimated through indirect calorimetry which measures oxygen consumption and carbon dioxide production.
It is Heat that is 'given off' by a chemical reaction.
When energy is lost in an environment, it is typically given off as heat. This heat can contribute to increasing the overall temperature of the environment.
The friction creates the heat.
The light and heat given off by the sun are actually high energy produced by nuclear fusion of hydrogen.
The term for extra heat given off by machines is "waste heat." It is the energy that is not used for the intended purpose of the machine and is instead released into the surrounding environment as heat.
On average, a human body gives off about 100 watts of heat.
yes heat is given of due to the exothermic process in some cases. e.g when caco3 is mixed with water heat is given of.

The heat given off by an object is called thermal energy. It is a form of energy that is transferred in the form of heat due to a temperature difference between the object and its surroundings.
