We’re being asked to determine the substance with the greatest temperature change when the same mass of each substance absorbs the same quantity of heat.
Recall that heat can be calculated using the following equation:
q = heat, J
• +q → absorbs heat
• –q → loses heat
m = mass (g)
c = specific heat capacity = J/(g·°C)
ΔT = Tf – Ti = (°C)
Since we are being asked for temperature change, we will first derive an equation for ΔT then determine the substance with the greatest temperature.
|Substance||Specific Heat (J/g-K)||Substance||Specific Heat (J/g-K)|
Table Specific Heats of Some Substances at 298 K
Which substance in the table undergoes the greatest temperature change when the same mass of each substance absorbs the same quantity of heat?
