AP EAMCET Engineering 2014 Code A Solved Paper

A steam at 100°C is passed into 1 kg of water contained in a calorimeter of water equivalent 0.2 kg at 9°C, till the temperature of the calorimeter and water in it is increased to 90°C. The mass of steam condensed in kg is nearly (sp. heat of water = 1 cal/g-°C, Latent heat of vaporisation = 540 cal/g)
