Answer:
The correct option is: a. The internal energy depends upon its temperature.
Explanation:
Ideal gas is a hypothetical gas that obeys the ideal gas law. The equation for the ideal gas law:
P·V=n·R·T
Here, V- volume of gas, P - total pressure of gas, n- total mass or number of moles of gas, T - absolute temperature of gas and R- the gas constant
Also, according to the Joule's second law, the <em><u>internal energy (U) of the given amount of ideal gas depends on the absolute temperature (T) of the gas only,</u></em> by the equation:
Here, 
<em>is the specific heat capacity at constant volume</em>
Semi-conductor,brittle not malleable or ductile.
