J (0) A copper can together with a stirrer of total heat capacity 60JK contains
200g of water at 10 °C. Dry steam at 100 °C is passed in while the water is
stirred until the whole reaches a temperature of 30 °C. Calculate the mass of
steam condensed. Specific heat capacity of water is 4,2001kg K and Specific
latent heat of vaporisation of water is 2,260,000 Jkg ​
