if the specifc heat of iron = 0.46J/g C,how much heat is needed to warm 50g of iron from 20C to 100C

-- I do not know how to make the celcius o above the temperature number

my anwswer

Q = Mx(delta)TxC
Q=50gx80Cx0.46J/gC
Q = 1840 Joules

Delta = the triangle I do not know how to make that on the computer
