You are designing a carnot engine that has 2 mol of co2 as its working substance; the gas may be treated as ideal. the gas is to have a maximum temperature of 516° and a maximum pressure of 5.00 atm . with a heat input of 405 j per cycle, you want 325 j of useful work. part a)
find the temperature of the cold reservoir.
express your answer using two significant figures.
part b)
for how many cycles must this engine run to melt completely a 9.00-kg block of ice originally at 0.0°c, using only the heat rejected by the engine?

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
