2. a. Take B °C, then convert it to Fahrenheit and Kelvin. b. Find the amount of heat needed to change the temperature of B g of ice from -D °C to B °C. The specific heat of water is 4186 J/kg °C, Latent heat of fusion is 3.33 x105 J/kg, laten heat of vaporization 2.25 x 106 J/ kg. c. A patient of mass B kg is spiking a fever of 105 Fahrenheit. The patient is immersed in ice bath 0°C ice to reduce the fever immediately back down to 98.6 Fahrenheit. How much ice must melt (bath stays at 0°C water) for this temperature reduction to be achieved? Latent heat of fusion is 3.33 x105 J/kg. and Specific heat of body is 3500 J/kg °C. d. A Styrofoam ice box has a total area of C/100 m² and walls with an average thickness of 2.50 cm. The box contains beverages at 0°C. The inside of the box is kept cold by melting ice.

2. What is the work done by a system when it absorbs 47 J of heat and gain 12 J of energy? 3. How much heat is released by a system when 45 J of work is done on it to decrease its energy to 23 J? 4. Suppose a woman does 500 J of work and 9500 J of heat transfer occurs into the environment in the process. What is the decrease in her internal energy, assuming no consumption of food? 5. A thermodynamic system undergoes a process in which its internal energy decreases by 500 J. If at the same time 220 J of work is done on the system, find the thermal energy transferred to or from it.
2. I just need the graph of this. A certain ideal gas (unknown) inside a close piston-cylinder assembly undergoes a set of processes that composed of Isothermal expansion from State point 1 to state point 2, Isometric heat rejection from state point 2 to state point 3, and Isentropic compression from state point 3 back to the initial condition. If the maximum pressure is 3000kPa and maximum and minimum volume is 200cm3 and 50cm3
