The statement that heat and work are equivalent implies that
The statement that heat and work are equivalent implies that
Options
- Aa body initially at rest can be set into linear motion by providing heat to it
- Bwhen heat is provided to a body, we perform work on it
- Cwhen work is performed on a body, we provide heat to it
- Dthe temperature of a body can be raised by performing work on it
Correct answer
D. the temperature of a body can be raised by performing work on it
Step-by-step solution
The equivalence of heat and work implies that both are forms of energy transfer that can produce the same effect on a system.
According to Joule's principle of the mechanical equivalent of heat, mechanical work done on a system can increase its internal energy, which manifests as a rise in its temperature.
This produces the exact same effect as supplying heat to the system. Therefore, the temperature of a body can be raised by performing work on it.
