What amount of heat is required to raise the temperature of 85.9 g of water by 7°c? the specific heat of water is 4.184 j/gºc.

2516 J.

Explanation:

Q = m.c.ΔT.

where, Q is the amount of heat required to raise the T of water,

m is the mass of water (m = 85.9 g),

c is the specific heat of ethanol in the gas phase (c = 4.184 J/g °C),

ΔT is the temperature difference (final T - initial T) (ΔT = 7.0 °C).

∴ Q = m.c.ΔT = (85.9 g)(4.184 J/g °C)(7.0 °C) = 2516 J.
