🌡️The formula to calculate the change in temperature of a substance when heat is added is q = msΔt.
🧪In the formula, q represents the heat energy, m is the mass of the substance, s is the specific heat, and Δt is the change in temperature.
🌡️For water, the specific heat is approximately 4.184 J/g°C.
🧪To find the change in temperature, rearrange the formula to Δt = q / (ms).
🌡️By substituting the given values into the formula, the change in temperature is calculated to be 31.7°C.
