If `150 kJ` of energy is needed for muscular work to walk a distance of one km, than how much of gulcose one has to consume to walk a distance of five km, provided only `30%` energy is available for muscular work.The enthalpy of combustion of glucose is `3000 kJ mol^(-1)`

If 150 kJ of energy is needed for muscular work to walk a distance of 1 km, then how much of glucose one has to consume to walk a distance of 5 km, provided only 30% of energy is available for muscular work. The enthalpy of combustion of glucose is 3000 kJ mol^-1

An average healthy man needs about 10000 kJ of enrgy per day.How much carbohydrates (in mass) he will have to consume assuming that all this energy needs are met only by carbohydrates in the form of glucose? The enthalpy of combustion of glucose is 2816 kJ "mol"^(-1) .

A cylinder of cooking gas contains 14.0 kg of butane. If a family needs 20,000kJ of energy per day for cooking, how long will the cylinder last? The enthalpy of combustion of butane is -2658 kJ mol^-1

An athlete is given 180 g of glucose (C_(6)H_(12)O_(6)) . He utilises 50% of the energy due to internal combustion in the body. In order to avoid storage of energy in the body, calculate the masss of water he would need to perspire. Given enthalpy of combustion of glucose is -2800 kJ mol^(-1) and enthalpy of evaporation of water is 44 kJ mol^(-1)

An athelet takes 20 breaths per minute at room temperature. The air inhaled in each breath is 200mL which contains 20% oxygen by volume, while exhaled air contains 10% oxygen by volume. Assuming that all the oxygen consumed if used for converting glucose into CO_(2) and H_(2)O_((l)) , how much glucose will be burnt in the body in one hour and what is the heat produced ? ( Room temperature -27^(@)C and enthalpy of combustion of glucose is -2822.5kJ mol^(-1) at 0^(@)C)
