An Ideal Carnot Heat Engine Operates Between Reservoirs at 1740 $150 \mathrm {~K}$

question 57

Short Answer

An ideal Carnot heat engine operates between reservoirs at 1740 K and $150 \mathrm {~K}$ In each cycle, 260 J of heat energy is rejected to the low temperature reservoir. In each cycle, how much mechanical work W is performed by the engine?

Presynaptic Cell

A presynaptic cell refers to the neuron that sends a message across the synaptic cleft, releasing neurotransmitters from its axon terminal.

Synaptic Cleft

The small gap between the presynaptic and postsynaptic neurons across which neurotransmitters are released to transmit signals.

Postsynaptic Cell

The neuron or cell that receives a signal (neurotransmitters) from another neuron at a synapse.

Neurotransmitter

Chemicals released by neurons at synapses, which transmit signals across a chemical synapse from one neuron to another neuron, muscle cell, or gland cell.
