Reciprocating steam engine: conversion of steam's thermal energy into mechanical work Confirm the basic working principle — heat in steam is converted into piston reciprocation and then shaft work. State whether the statement is true or false.

Difficulty: Easy

• True — heat energy in steam → piston to-and-fro motion → work
• False — all energy conversion happens only in the condenser
• False — conversion occurs only in the boiler
• False — steam energy cannot be converted to mechanical work
