2. (16%) (a) How much 0°C ice are required to add to 500g of 90°C water such that the final temperature of all water is 30°C? (Specific heat capacity of water = 4200Jkg ¹C¹, specific latent heat of fusion of ice = 3.34×10 Jkg¹, specific heat capacity of ice = 2108 Jkg-¹°C+¹) (b) The volume of an ideal gas is decreased from 1.1 m² to 0.84 m³ while maintaining a constant pressure of 990 Pa (1 Pa = 1 N/m²). How much work is done on the gas to compress it? (c) An insulated cylinder contains an ideal gas B... The volume of gas B is 1050 cm³. Its pressure is 0.8 x 10³ Pa... The number of molecules of gas B in the cylinder is 2.4X10 Find the temperature of the gas B in degree Celsius. (d) State and explain whether it is possible to move heat from cooler environment to hotter environment.
