Our bodies convert internal chemical energy into work and heat at the rate of about 100 W, which is called our metabolic rate. (a) How much internal chemical energy do we use in 24 h? (b) The energy comes from the food that we eat and is usually measured in kilocalories, where 1 kcal = 4.184 kJ. How many kilocalories
Our bodies convert internal chemical energy into work and heat at the rate of about 100 W, which is called our metabolic rate.
(a) How much internal chemical energy do we use in 24 h?
(b) The energy comes from the food that we eat and is usually measured in kilocalories, where 1 kcal = 4.184 kJ. How many kilocalories of food energy must we ingest per day if our metabolic rate is 100 W?
