Question

If an ideal flask containing hot coffee is shaken, the temperature of the coffee will : (A) decrease (B) increase (C) remain same (D) decrease if temperature is below 4° C and increase if temperature is equal to or more than 4° C

Tardigrade Admin · Accepted Answer

We know that there is no loss of heat in an ideal flask. Therefore mechanical energy wasted in shaking, is changed into heat energy and hence, temperature rises.

Q. If an ideal flask containing hot coffee is shaken, the temperature of the coffee will :

decrease

increase

remain same

decrease if temperature is below $4^{\circ} C$ and increase if temperature is equal to or more than $4^{\circ} C$
