Question

Steam at $$1000C$$ is passed into $$1.1$$ kg of water contained in a calorimeter of water equivalent $$0.02$$ kg at $$150C$$ till the temperature of the calorimeter and its contents rises to $$800C$$. The mass of the steam condensed in kg is

Infinity Learn · Accepted Answer

Heat is lost by steam in two stages (i) for change of state from steam at $$1000C$$ to water, (ii) to water at $$800C$$ is m×$$1$$×(100-80), where m is the mass of steam condensed.Total heat lost by steam $$=$$ m × $$540$$ $$+$$ m×$$20$$ $$=$$ $$560m$$ cal Heat gained by calorimeter and its contents $$=$$ (1.1$$ $$+$$ $$0.02) ×(80-15) $$=$$ $$1.12$$ ×$$65$$ calUsing principle of calorimetryHeat gained $$=$$ heat $$lost560$$ m $$=$$ $$1.12$$ × $$65m$$ $$=$$ $$0.130$$ gm

Steam at $100^{0} C$ is passed into 1.1 kg of water contained in a calorimeter of water equivalent 0.02 kg at $15^{0} C$ till the temperature of the calorimeter and its contents rises to $80^{0} C$ . The mass of the steam condensed in kg is
