Question

A silver ring has a mass of 138.45 g. How many joules of heat are required to increase the temperature from 11.8 ∞C to 162.5 ∞C?

[5007 J]<==== Answer

Answer 1

q = mC∆T

q = heat = ?

m = mass = 138.45 g

C = specific heat = 0.235 J/gº (I looked this up so you may have a slightly different value)*

∆T = change in temperature = 162.5º - 11.8º = 150.7º

q = (138.45 g)(0.235 J/gº)(150.7º)

q = 4903 J

1. This differs from the given answer because whoever solved the problem before must have used a different value for C
