Explanation:
It is known that relation between heat energy, mass and temperature change is as follows.
q =
where, C = specific heat of water (in given case) = 4.184
m = mass
= change in temperature
Therefore, calculate the heat energy as follows.
q =
=
= 1255.2 kJ/day
For 10 days, total heat required is as follows.
= 12552 kJ
It is known that the value of standard enthalpy of combustion of butane is -49.5 kJ/g.
Therefore, combustion of 1 gm of butane will be 49.5 kJ. Hence, total amount of butane required will be as follows.
= 253.57 g
As it is given that 1 canister of butane contains 75 g butane. Hence, no. of canisters required are as follows.
No. of canisters required =
= 3.38
= 4 (approximately)
Thus, we can conclude that minimum number of fuel canisters you must bring are 4.
