Heat and Thermodynamics question

2022 · 26 Jun · Shift 2 · Q67

JEE MainPhysicsHeat and ThermodynamicsNumerical+4 / −1
A geyser heats water flowing at a rate of 2.0 kg per minute from 30 ∘^\circ∘ C to 70 ∘^\circ∘ C. If geyser operates on a gas burner, the rate of combustion of fuel will be ‾\underline{\hspace{2cm}}​ g min −-− 1. [Heat of combustion = 8 ×\times× 103 Jg −-− 1, Specific heat of water = 4.2 Jg −-− 1 ∘^\circ∘ C −-− 1]
