The initial temperature of 150 g of ice is -20°C. The spe-cific heat capacity of ice is 0.5 cal/g.C° and water's is1 cal/g•C°. The latent heat of fusion of water is 80 cal/g.a.How much heat is required to raisethe ice to 0°C andcompletely melt the ice?b. How much additional heat is required to heat the water(obtained by melting the ice) to 25°C?C.What is the total heat that must be added to convert the80 g of ice at-20°C to water at +25°C?d. Can we find this total heat simply by computing howmuch heat is required to melt the ice and adding theamount of heat required to raise the temperature of 80 gof water by 45°C? Explain

4. Ideal Gas Type Question: A piston comprises two nested cylinders which are 3 cm and 2.8 cm in diameter with 0.1 cm thick walls and are each 1 m long. Initially, the smaller cylinder sits completely inside the larger cylinder and is filled with N2 at 20 °C and atmospheric pressure. a. C. The gas is slowly heated, while the cylinder is allowed to freely expand. What kind of process is this? banc b. The smaller cylinder has a total mass of 1.5 kg. What temperature does the gas need to be for the cylinder to become fully extended? The cylinder can withstand an internal pressure of 20 atm. What's the maximum weight it can lift? e. d. A 100 kg weight is dropped on the cylinder while it is fully extended, causing it to rapidly compress. What kind of process is this? If the cylinder is fully depressed by this event, what is the peak pressure? The adiabatic constant for N2 is 7/5. f. If the weight is dropped from 2 m, assuming 1% of its energy is converted into thermal energy in the gas,…
