Question

The Watt engine is over three times more efficient than the Newcomen engine. Which of the following explains why this is? it was smaller and so would create less steam it used a separate condenser to cool steam so that the boiler cylinder always remained hot it used steam to pull the piston down causing it to have constant motion it used more contained explosions thus losing more energy to the surroundings

Answer 1

The Watt engine was more efficient than the Newcomen engine due to its use of a separate condenser, steam-powered motion, and reduced fuel consumption.

Step-by-step explanation:

James Watt's steam engine was more efficient than the Newcomen engine for several reasons:

1. It used a separate condenser to cool steam. By cooling the steam separately from the boiler cylinder, the cylinder always remained hot. This allowed for greater efficiency in converting heat energy into mechanical work. In contrast, the Newcomen engine relied on the hot cylinder to cool the steam, resulting in energy loss.
2. It used steam to pull the piston down, causing constant motion. By utilizing steam power to drive the piston, Watt's engine achieved continuous and smooth motion, whereas the Newcomen engine had a rocking motion.
3. It required less fuel. Watt's engine was smaller and required only a quarter as much fuel as the Newcomen engine to produce the same amount of power.
