Answer : 3. "Specific Heat formula"
Explanation :
Answer: C) Specific Heat formula Explanation: Q = mc∆T refers to Specific Heat formula. When heat energy is added to a substance, the temperature will change by a certain amount. The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate. Q = mc∆T Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) ∆T = change in temperature (Kelvins, K)
