Question

Quizplus · Accepted Answer

The formula to calculate the heat released by a substance is:

q = m * C * ΔT

Where:
q = heat released
m = mass of the substance (in grams)
C = specific heat of the substance
ΔT = change in temperature (in °C)

Substituting the given values:

q = 25.0 g * 1.00 cal/(g x °C) * (95.0 °C - 20.0 °C)
q = 1.88 x 103 cal

Therefore, the answer is D) 1.88 x 103 cal.
