General Physics 3 Mock Exam 2

A $2.0 \text{ mg}$ droplet of liquid nitrogen is present in a $30 \text{ mL}$ tube sealed at very low temperature. What will the nitrogen pressure in the tube be when it is warmed to $20^\circ C$? Assume the nitrogen behaves as an ideal gas. The molar mass of nitrogen ($N_2$) is $28 \text{ g/mol}$. ($R = 8.314 \text{ J/(mol}\cdot\text{K)}$, $1 \text{ atm} = 1.01 \times 10^5 \text{ Pa}$)

The only elastic modulus that applies to liquids is:

If a sealed container of liquid and a sealed container of gas are both subjected to a significant increase in external pressure, analyze which substance would experience a more substantial percentage change in volume and explain why.

Calculate the work done by a system if $500 \text{ J}$ of heat is added to it and the change in internal energy of the system is $350 \text{ J}$.

Convert an average human temperature of $98.6^\circ F$ to Celsius.

Which statement accurately describes the motion of particles in a transverse wave compared to a longitudinal wave?

Determine the pressure of a constant volume of gas when it is heated from $30.0^\circ C$ to $40.0^\circ C$, if the initial pressure was $2.00 \text{ atm}$.

The temperature difference between the inside and outside of a home is $57.0^\circ F$. Express this temperature difference in Celsius.

The SI unit of temperature is:

Determine the pressure change when a constant volume of gas at $2.00 \text{ atm}$ is heated from $30.0^\circ C$ to $40.0^\circ C$.
