Small objects vibrate quickly and produce lots of waves each second, and as the length of the bells are short the wave length become short too,so small bells have a high frequency hence high pitch.
Answer:
Internal energy increases when heat is transferred to the system
Explanation:
To answer this question you can make use of the first law of thermodynamics, which is a way to state the conservation of energy:
Where U is the internal energy of the system
Q is heat, and W is work done by the system.
This law tells us that the change in internal energy is proportional to the heat added to the system minus the work done by the system.
So for the internal energy of a system to increase, heat must be added to it.
