What are two factor in which heat energy of a body depends?
Heat liberated by a body depends on the mass of the body, the specific heat capacity of that body and the change in temperature experienced by the body.
What are the factors that affect the amount of heat?
This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material . Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance .
What is the amount of heat energy contained in a body?
Explanation:Temperature tells us how hot or cold the body is.
What are the factors on which the energy requirement of a person depends?
Gender, age and body weight are the main determinants of total energy expenditure. Thus, energy requirements are presented separately for each gender and various age groups, and are expressed both as energy units per day and energy per kilogram of body weight.
What 3 factors will affect the amount of energy a person requires?
What are the three factors that determine a person’s daily energy expenditure?
Daily energy expenditure is composed of three major components: 1) resting metabolic rate (RMR); 2) the thermic effect of feeding (TEF); and 3) the thermic effect of activity (TEA).
What is heat transfer by radiation?
Radiation heat transfer is a process where heat waves are emitted that may be absorbed, reflected, or transmitted through a colder body. Sun heats the earth by electromagnetic waves. Hot bodies emit heat waves.
What are factors that affect the amount of heat energy and temperature of a substance?
The thermal energy of an object depends on its temperature and mass. The higher the temperature of a substance, the more thermal energy it has. For the same temperature, a substance with a higher mass will also have more thermal energy.
What factors affect the amount of energy we need?
What are the factors affecting energy intake?
The factors discussed in the present systematic review are namely physical activity level, socioeconomic status, diet ,individual and social factors which do have an impact on energy intake and eating habits.
What are the 3 factors that contribute to total daily energy expenditure TDEE and approximately what of TDEE does each one make up?
Daily energy expenditure is composed of three major components: 1) resting metabolic rate (RMR); 2) the thermic effect of feeding (TEF); and 3) the thermic effect of activity (TEA). RMR constitutes 60 to 75% of daily energy expenditure and is the energy associated with the maintenance of major body functions.
