If you apply some heat energy to a substance , which of the following can take place in it ? a) expansion b)increase in temperature c) change of state d)all the above​

Answer 1

Answer:

d

Explanation:

this is the right answer

Answer 2

All of the above (ie. expansion, increase in temperature, change of state) can take place in it. (option D)

• Whenever we apply some heat energy to an object, the following things can happen -

1. Thermal expansion is very common, whenever we apply heat to an object.
2. The temperature of the object will obviously increase of that object.
3. State of the object may also change (eg. solid to liquid, liquid to gas etc.) if required amount of heat is applied.

• So, the things which are mentioned in option a,b,c , all can happen whenever we apply some heat to an object.
• That's why, the correct answer of this question will be "all of the above" (option D).
