A cryosurgical probe uses the vaporization of liquid nitrogen to destroy abnormal tissue. The specific latent heat of vaporization of liquid nitrogen is 1.99 × 105 J/kg.

During a brief medical procedure, 35.0 g of liquid nitrogen at its boiling point is completely vaporized.

Calculate the thermal energy absorbed by the nitrogen during this process.
