To find the change in temperature, we can use the formula:
Q = m * c * ΔT
Where:
Q = heat absorbed or released (in joules)
m = mass of the substance (in grams)
c = specific heat capacity (in J/g•C)
ΔT = change in temperature (in Celsius)
Rearranging the formula to solve for ΔT, we have:
ΔT = Q / (m * c)
Substituting the given values:
m = 2.51 g
c = 0.382 J/g•C
Q = 2.75 J
ΔT = 2.75 J / (2.51 g * 0.382 J/g•C)
ΔT = 2.75 J / 0.95782 J/°g
ΔT = 2.867180624 °C
Therefore, the change in temperature is approximately 2.87 °C.
