Question

A sample of an ideal gas having an internal energy U, is then compressed to one half of its original volume, while the temperature remains same. What is the new internal energy of the ideal gas in terms of U

• A. U
• B. $\frac{1}{2}U$
• C. $\frac{1}{4}U$
• D. 2U

Answer 1

The correct option is A U

If temperature is constant, U will remain unchanged as internal energy for an ideal gas is the function of temperature
