Measuring Specific Heat Using Calorimeter

Q.

Steam at $100{}^{\circ }C$ is passed into $1.1kg$ of water contained in a calorimeter of water equivalent $0.02kg$ at $15{}^{\circ }C$ till the temperature of the calorimeter and its contents reaches $80{}^{\circ }C$. Considering the latent heat of steam $=540cal{g}^{-1}$ $\mathrm{and}{s}^{}$pecific heat capacity of water $=4183Jk{g}^{-1}{K}^{-1}$ ${\mathrm{or}}^{}$ $=1calk{g}^{-1}{K}^{-1}$,
calculate the mass of the steam condensed.

1. 0.130

2. 0.065

3. 0.260

4. 0.145
