An astrophysicist uses liquid nitrogen to cool an infrared detector.

Calculate the thermal energy absorbed when 140.0 g of liquid nitrogen vaporises to gas at its boiling point.

The specific latent heat of vaporisation of nitrogen, LLL, is 1.99 × 105 J/kg.

Use the equation:

E=m×L E = m \times L E=m×L
