The amount of work done by a heat engine equals the amount of thermal energy?
The amount of work done by a heat engine is not equal to the amount of thermal energy it absorbs. In a heat engine, only a fraction of the thermal energy absorbed is converted into work, with the remaining energy typically being expelled as waste heat. The efficiency of a heat engine is a measure of how effectively it converts thermal energy into work.
The amount of work done by a heat engine equals the amount of thermal energy .?
The amount of work done by a heat engine is equal to the difference between the heat input and the heat output. This is based on the first law of thermodynamics, which states that energy cannot be created or destroyed, only transformed. In a heat engine, this transformation occurs from thermal energy to mechanical work.
How much work is done by the heat engine if it takes in 2000J of heat and rejects 1500J of heat?
Work done=Heat in-Heat out 2000-1500=500J
How to calculate the efficiency of a heat engine?
To calculate the efficiency of a heat engine, you can use the formula: Efficiency (Work output / Heat input) x 100. This formula compares the amount of useful work produced by the engine to the amount of heat energy it takes in. The efficiency is expressed as a percentage, with higher percentages indicating a more efficient engine.
Which describes the work done by the heat engine?
A heat engine converts heat energy into mechanical work. It operates by taking in heat from a high-temperature source, using it to do work, and then releasing the remaining heat to a low-temperature sink. The efficiency of a heat engine is the ratio of the useful work output to the heat input.

What is the definition of thermal efficiency?
the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.

How does the amount of work done on an automobile by its engine relate to the energy content of the gasoline?
The amount of work done on an automobile by its engine is directly related to the energy content of the gasoline used as fuel. Gasoline contains potential energy stored in its chemical bonds, which is released during combustion in the engine to produce work that moves the vehicle. The higher the energy content of the gasoline, the more work can be done by the engine.
A measure of heat energy?
A measure of heat energy can be done easily using a thermometer. This will measure the amount of thermal energy transferred.
How does the amount of working gas affect the efficiency of a heat engine?
The efficiency of a heat engine is affected by the amount of working gas it contains. A larger amount of working gas can lead to higher efficiency because it allows for more energy to be converted into useful work. Conversely, a smaller amount of working gas may result in lower efficiency as there is less gas available to transfer heat and produce work.
In carnot's heat engine why is the heating done at extremely slow rate?
Yes , its a quasi equilibrium process so heat is added slowly
