An 80-kg patient has the flu and his temperature increases from 37°C to 39°C: c = 3 470 J/(kgK). How much extra heat do the chemical reactions in his cells have to generate to cause this temperature change? (6 x 105 J)

Q = 555200 J

Explanation:

∴ mass (m) = 80 kg

∴ c = 3470 J/Kg.K

∴ T1 = 37°C ≅ 310 K

∴ T2 = 39°C ≅ 312 K

⇒ ΔT = T2 - T1 = 312 K - 310 K = 2 K

⇒ Q = (80 Kg)*(3470 J/Kg.K)*(2 K)

⇒ Q = 555200 J ≅ 600000 J ≅ 6 E5 J

the answer would be a
