To solve the problem of calculating the mass of steam needed to just melt the ice in the thermos flask, we can follow these steps: ### Step-by-Step Solution: 1. **Identify Given Data:** - Mass of ice (m_ice) = 100 g - Mass of water (m_water) = 30 g - Latent heat of fusion of ice (L_f) = 336 J/g ...

In a container of negligible heat capacity, 200 gm ice at 0^(@)C and 100gm steam at 100^(@)C are added to 200 gm of water that has temperature 55^(@)C . Assume no heat is lost to the surrpundings and the pressure in the container is constant 1.0 atm . (Latent heat of fusion of ice =80 cal//gm , Latent heat of vaporization of water = 540 cal//gm , Specific heat capacity of ice = 0.5 cal//gm-K , Specific heat capacity of water =1 cal//gm-K) Amount of the steam left in the system, is equal to

Heat required to convert 1 g of ice at 0^(@)C into steam at 100 ^(@)C is

A mass m of steam at 100^(@)C is to passed into a vessel containing 10g of ice and 100g of water at 0^(@)C so that all the ice is melted and the temperature is raised to 5^(@)C neglecting heat absorbed by the vessel, we get

A tube leads from a flask in which water is boiling under atmospheric pressure to a calorimeter. The mass of the calorimeter is 150 g, its specific heat capacity is 0.1 cal//g//^@C , and it contains originally 340g of water at 15^@C . Steam is allowed to condense in the colorimeter until its temperature increases to 71^@C , after which total mass of calorimeter and contents are found to be 525g. Compute the heat of condensation of steam.

Steam at 100^@C is allowed to pass into a vessel containing 10g of ice and 100 g of water at 0^@C until all the ice is melted and the temperature is raised to 50^@C . Neglecting water equivalent of the vessel and the loss due to radiation etc. Calculate how much steam is condensed.
