(b) A certain mass of steam, initially at 130 °C is used to warm 200g of water in a 100g glass container from 20.0 °C to 50.0 °C. Assume that the steam condenses and ends up in thermal equilibrium with the glass and water (i.e. at 50°C). Data: (i) (ii) Csteam=2010 J/kg.°C Cwater=4186 J/kg.°C Class = 837 J/kg.°C Latent heat of vaporisation L, = 2.26 x 10° J/kg How much heat does the glass require in this process? What mass of steam is required for this process? Show your reasoning.
