To calculate the amount of energy required to raise the temperature of a substance, you can use the formula:
q = m * C * ΔT
Where:
q = amount of energy (in joules)
m = mass of the substance (in grams)
C = specific heat capacity of the substance (in J/g°C)
ΔT = change in temperature (in °C)
For gaseous nitrogen, the specific heat capacity (C) is approximately 0.248 J/g°C.
Plugging in the values for this problem:
m = 11.0 g
C = 0.248 J/g°C
ΔT = (39.6 °C - 20.9 °C) = 18.7 °C
q = 11.0 g * 0.248 J/g°C * 18.7 °C
Calculating the result:
q = 46.1064 Joules
Therefore, the amount of energy required to raise the temperature of 11.0 grams of gaseous nitrogen from 20.9 °C to 39.6 °C is 46.1064 Joules.
