WebAug 2, 2024 · Solution. We can use heat = mc Δ T to determine the amount of heat, but first we need to determine Δ T. Because the final temperature of the iron is 73.3°C and the initial temperature is 25.0°C, Δ T is as follows: ΔT = Tfinal − Tinitial = 73.3°C − 25.0°C = 48.3°C. The mass is given as 150.0 g, and Table 7.3 gives the specific heat ... WebStep 2: Plug in these values into the heat equation. Q = m x C x Δt. Q = 53 g x 4.184 J/g°C x 33°C. Q = 7300 J. How much heat is released when 21 g of Al cools from 31.0°C to 27.0°C? Step 1: Identify what is given in the problem. m = 21 g. If the substance is known, the value of C can be found on a chart like the one above. C = 0.89 J/g°C.
WebOct 4, 2024 · Specific Heat Equation and Definition . First, let's review what specific heat is and the equation you'll use to find it. Specific heat is defined as the amount of heat per unit mass needed to increase the temperature by one degree Celsius (or by 1 Kelvin). Usually, the lowercase letter "c" is used to denote specific heat. The equation is written:
