Calculate the amount of heat required to raise the temperature of 3 moles of
oxygen gas from 298 to 400K. Given that C, of O2 is 29.36 Jmole-'K-'.
Please show how to do it.
To calculate the amount of heat (q) required to raise the temperature of a substance, we can use the formula:
q = n * C * ΔT
where:
q = amount of heat (in Joules)
n = number of moles of the substance
C = molar heat capacity (in J/mol*K)
ΔT = change in temperature (in Kelvin)
In this case, you are given that the number of moles of oxygen gas (O2) is 3, the molar heat capacity (C) is 29.36 J/mol*K, and the change in temperature (ΔT) is 400K - 298K = 102K.
Now, we can substitute these values into the formula:
q = 3 moles * 29.36 J/mol*K * 102K
Calculating this expression will give us the amount of heat required to raise the temperature of 3 moles of oxygen gas from 298K to 400K.
