Delta, or the “Δ” symbol, represents the change in a variable. For example, if your first temperature (T1) is 150ºC, and your second temperature (T2) is 20ºC, then ΔT, or the change in temperature, represents 150ºC - 20ºC, or 130ºC. The mass of the sample is represented by “m”. The amount of heat is represented by “Q”. The amount of heat is represented by “J”, or Joules. “T” is the temperature of the substance. Specific heat is represented by “Cp”.
You can manipulate this formula if you want to find the change in the amount of heat instead of the specific heat. Here’s what it would look like: ΔQ = mCpΔT
You can manipulate this formula if you want to find the change in the amount of heat instead of the specific heat. Here’s what it would look like: ΔQ = mCpΔT
m = 350 g Q = 34,700 Joules ΔT = 173ºC - 22ºC = 151ºC Cp = unknown
Original equation: Cp = Q/mΔT c = 34,700 J/(350 g x 151ºC)
Cp = 34,700 J/(350 g x 151ºC) Cp = 34,700 J/(52850 g x ºC) Cp = 0. 65657521286 J/(g x ºC)
