Carnot engine takes $1000 \mathrm{~K}$ cal of heat from a reservoir at $827^{\circ} \mathrm{C}$ and exhausts it to a sink at $27^{\circ} \mathrm{C}$. How much heat is rejected to the sink? What is the efficiency of the engine?

Key Concepts

Heat Transfer Ratios

In a Carnot engine, there is a direct proportionality between the heat rejected to the cold reservoir and the heat absorbed from the hot reservoir, which is determined by the ratio of their absolute temperatures. This relationship underlies the calculation of the rejected heat in ideal heat engines.

Temperature Conversion

Thermodynamic calculations require the use of absolute temperatures, typically measured in Kelvin. Converting from Celsius to Kelvin (by adding 273.15) is crucial for accurately applying formulas like those for Carnot efficiency.

Carnot Cycle

The Carnot cycle is an idealized thermodynamic cycle that consists of two isothermal and two adiabatic processes. It represents the most efficient possible engine operating between two reservoirs and forms the basis for understanding real engine limitations.

Carnot Efficiency

Carnot efficiency is defined as 1 minus the ratio of the absolute temperature of the cold reservoir to that of the hot reservoir, expressed as ? = 1 - (T_cold/T_hot). This concept establishes the maximum efficiency that any heat engine can achieve when operating between given temperature limits.
