AP EAMCET · PHYSICS · Thermal Properties of Matter
A steam at \(100^{\circ} \mathrm{C}\) is passed into \(1 \mathrm{~kg}\) of water contained in a calorimeter of water equivalent \(0.2 \mathrm{~kg}\) at \(9^{\circ} \mathrm{C}\) till the temperature of the calorimeter and water in it is increased to \(90^{\circ} \mathrm{C}\). The mass of steam condensed in \(\mathrm{kg}\) is nearly (specific heat of water \(=1 \mathrm{cal} / \mathrm{g}{ }^{\circ} \mathrm{C}\), latent heat of vaporisation \(=540 \mathrm{cal} / \mathrm{g}\) )
