Mechanical Properties Of Fluid

We use the principle of conservation of energy. The heat gained by the ice equals the heat lost by the steam. 1. Heat required to melt the ice: where and (latent heat of fusion). 2. Heat required to raise the temperature of the ice to 0°C: where (specific heat capacity of ice) and . 3. Heat required to convert 25 g of steam at 100°C to water at 100°C: where and (latent heat of vaporization). Now, using conservation of energy: The correct answer shows that at thermal equilibrium, 100°C water and 20 g of steam are present. Thus, the correct answer is .

The root mean square (rms) speed of gas molecules is given by: where is the absolute temperature. Since , we can write: Converting temperatures to Kelvin: Percentage increase: Thus, the correct answer is .
