Question 2

A laboratory researcher uses liquid nitrogen to cool a high-temperature superconducting sensor. During the process, some liquid nitrogen vaporises at its boiling point.

Calculate the thermal energy absorbed to vaporise 165 g of liquid nitrogen at its boiling point. The specific latent heat of vaporisation of nitrogen, $L$ , is 1.99 × 10⁵ J/kg.

Use the equation:

\times L
