Final answer:

The amount of heat required to raise the temperature of one mole of oxygen from 300K to 1300K at constant pressure is 29400 Joules.

Step-by-step explanation:

To calculate the amount of heat required to raise the temperature of one mole of oxygen from 300K to 1300K at constant pressure, we can use the equation:

q = nCpΔT

Where:

  • q is the heat
  • n is the number of moles of oxygen
  • Cp is the molar heat capacity
  • ΔT is the change in temperature

For oxygen gas, the molar heat capacity at constant pressure is approximately 29.4 J/(mol·K). Plugging in the values:

n = 1 mole

Cp = 29.4 J/(mol·K)

ΔT = (1300K - 300K) = 1000K

Substituting these values into the equation:

q = (1 mole)(29.4 J/(mol·K))(1000K) = 29400 J

Therefore, the amount of heat required is 29400 Joules.
