There was a block of ice in an isolated container at temperature 0 ْC. We wanted to determine its mass, therefore we led some steam of temperature 100 ْC into the container, but we could not determine the exact amount of the steam. After re-closing the container all the ice melted, and the new equilibrium temperature became 10 ◦C. Then, once more we led some steam of temperature 100 ◦C into the container, but again, we could not determine its exact amount. The temperature in the container became 15ْC. Finally, we led again some steam into the container, and this time we could determine its mass, which was 0.3 kg. The new equilibrium temperature in the container became 23 ْC. Determine the mass of the ice block!
