need help with question 6 please

UNKNOWN SAMPLE Number: (same as Experiment 3, density determination of a metal) TRIAL 1 TRIAL 2 1) Mass of Styrofoam Cups (nearest 0.01 g) 4.28% 4to 2) Mass of Styrofoam Cups +Water (100 mL) lole t Jou (nearest 0.01 g) 3)Initial Water Temperature, Tto (nearest 0.1°C) 22.0% 4) Initial Temperature of the heated metal, Tm ) (nearest 0.1°C) 5) Highest Temperature reached by metal + Water da.oc (T), (nearest 0.1°C) 6) Mass of Styrofoam Cups + Water + Metal 935.5 (nearest 0.01 g)

Explanation / Answer

Specific heat of the metal = m * C * T

Where Can is the specific heat of the metal .

Here energy gained by water = 2861 Joule ( you calculated in the question 3 )

This heat will be equal to heat lost by metal

m * C * T = 2861

133.62 * C * 59 = 2861

C = 0.363 j / g °C

If you satisfied with the solution please like it thankxx
