Question
As heat is applied to a solid substance, the temperature _________ and remains constant until the solid state converts to liquid.
- Increases
- Decrease
- Remains same
- None of these
Hint:
The application of heat means an increase in temperature.
The correct answer is: Increases
- When heat is applied to a solid temperature increases, and the internal energy of the solid increases.
- Molecules start to vibrate.
- A stage is reached when with the addition of heat temperature remains constant until the solid state gets converted to liquid.
- So, initially on applying heat temperature increases and remains constant until the solid changes to a liquid.
