Question

the tempreature of an object will surely change if it is heated. true or false​

Answer 1

Answer:

False

Explanation:

According to the first law of thermo,

Del U = Del Q - W

⇒ nCvΔT = ΔQ - W

Imagine if the process is isothermal (T=constant) , ΔT=0,

ΔQ = W

So the amount of heat supplied is equal to the work done but the temperature did not change.
