Brett Foley · Answer 1

Answer:a. 0.723 J / (g. °C)

Explanation:

Q = mCΔT

where,

Q - Quantity of heat supplied- = 253.0j

m - mass of substance=10g

C - specific heat capacity=?

ΔT - change in temperature = 60 - 25 = 35°C

Imputing values, we have,

Q = mCΔT

C = Q / (mΔT) = 253.0 / (10 x 35) = 0.7228 rounded to - --> 0.723 J / (g. °C)
