To find the temperature increase of nitrogen, we can use the formula:
ΔT = Q / (m * Cv)
where:
ΔT = temperature increase
Q = amount of heat energy supplied
m = mass of the substance
Cv = specific heat capacity at constant volume
In this case, we have:
Q = 600 J (amount of heat energy supplied)
m = 280 g (mass of nitrogen) = 0.28 kg (since 1 kg = 1000 g)
Cv = 750 J/(kg.K) (specific heat capacity at constant volume)
Now we can substitute the values into the formula to calculate the temperature increase:
ΔT = 600 J / (0.28 kg * 750 J/(kg.K))
First, we simplify the units:
ΔT = 600 J / (0.21 J/K)
Now we can calculate the temperature increase:
ΔT = 2857.14 K
Therefore, the temperature of nitrogen increased by approximately 2857.14 K.
