Please show work Problem-5. Warming 1 kg of water requires 4.186 kJ of energy per degree Celsius. About how many hours would it take to warm 1 L of water from 20° C to 40° C if you immerse in the water a 100 12 resistor connected across two 9.0-V batteries aligned in series?
How much energy is dissipated as heat during a two-minute time interval by a 1 .5-k ohm resistor which has a constant 20-V potential difference across its leads? a) 58 J b) 46 J c) 32 J d) 72 J e) 17 J When a voltage VI is placed across a series combination of an unknown resistor R and a 65-ohm resistor, the power delivered to the resistors is Pl. When the 65-ohm resistor is replaced by a 20-ohm resistor...
Chose the correct answer(s) from the multiple choice lists below 1. Exergy of a system is a) b) always increasing e) guided by the first and second laws of thermodynamics for reversible processes only Un d) limited by the second law of thermodynamics for all processes. processes, it is destroyed partly or completely). e) equal to the Gibs free energy of the system. 211two electrodes, one made of u (E.-3.06 V) and another made of Cu ΟΕ.+034V placed in an...
