How much energy is required to raise the temperature of 175g of water from -11C to 140C

Answer 1

The specific heat of water is 4.184 J/g/deg, meaning that it takes 4.184 joules of energy to raise the temperature of 1 g of water by 1 degree. So, you can use the formula/equation that q = mC∆T where

q = heat = ?

m = mass = 175 g

C = specific heat = 4.184 J/g/deg

∆T = change in temperature = 140º - (-11º) = 151º

q = (175 g)(4.184 J/g/deg)(151 deg)

q = 110,562 joules = 110.6 kilojoules = 110.6 kJ
