Question

1. in which thermodynamic process would you expect the greatest temperature change for a given amount of energy input? mark only one oval. the temperature change is the same in all processes isochoric process isothermal process isobaric process 29. a pendulum swings back and forth. at the highest point of its swing, what type of energy is maximized? mark only one oval. potential energy only neither kinetic nor potential energy kinetic energy only both kinetic and potential energy equally

Explanation:

Question 28

• Isothermal process: Temperature remains constant ($\Delta T = 0$), so no temperature change for energy input.
• Isobaric process: $Q = nC_p\Delta T$, where $C_p$ (molar specific heat at constant pressure) is greater than $C_v$ (molar specific heat at constant volume).
• Isochoric process: $Q = nC_v\Delta T$. Since $C_v

Question 29

• At the highest point of a pendulum's swing:
• Velocity $v = 0$. Kinetic energy $K=\frac{1}{2}mv^{2}=0$ (so kinetic energy is not maximized or present).
• Height $h$ is maximum. Potential energy $U = mgh$ (where $m$ is mass, $g$ is acceleration due to gravity, $h$ is height). So potential energy is maximized.

Answer:

1. Isochoric process
2. Potential energy only
