How much heat is required to raise the temperature of 50g of water from 20ᵒC to 150ᵒC? The specific heat of water is 4.184 J/gᵒC.

Answer 1

Use the equation: q = mC∆T

q = heat = ?

m = mass = 50 g

C = specific heat = 4.184 J/gº

∆T = change in temperature =150º - 20º = 130º

q = (50 g)(4.184 J/gº)(130º) = 27,196 J
