Question

An office heater puts out 2070 Btus (British thermal units) of energy in the form of heat per hour. Given that 1 Btu = 1.055 kJ, how many megajoules of energy in the form of heat can be produced per year (365 days) by the heater (assume continuous operation)?

Answer 1

2070 BTU/hr x 24 hr/day x 365 d/yr = ?BTU
?BTU x 1.055 kJ/BTU = ? kJ.
? kJ x (1 MJ/1000 kJ) = ? MJ.
