Temperature in K 200 10 15 20 25 Time in minutes The graph shows the temperature vs time for 1kg of a material being heated with a constant power P, starting in its solid phase. If he latent heat of fusion for this material is 300 kJ/kg, which of the following is closest to the power P? O 0.5kW O 10KW O 4KW O 2KW O 1KWThree cylinders of gas are compressed, one isobarically, one isothermally, and one adiabatically. If W is the same in all cases, for which case is AU largest? (Note: here, negative values of AU should be considered to be smaller than positive values, regardless of their magnitude) O In the isobaric (constant pressure) case O AU is the same in all cases O In the adiabatic case O In the isothermal case
