想詢問一下這三題的算式及原理 謝謝

3. 一質量為 1 kg 的小球由靜止沿著斜坡從高度5m處 m/s。請問下滑過程中,摩擦力產 (A) 18 (B) 32 (C) 50 (D) 68 (E) 82 。 滑下,滑到底部時,速 率 為8 生多少J的熱能?(設重力加速度為10m/s)

（7）怎麼寫😅

(4) Please describe the differences between ideal gas and real gas (2%) (5) In Van der Waals equation of state, please describe the meaning of parameter "a" and "b" briefly.(4%) (6) Please define Gibbs free energy (G), state the limiting factors and the meaning of Gibbs free energy [3%] (7) According to (4). Please provide two possible forms of energy that might affect the Gibbs free energy of a system. [2%]

第四小題，旁邊一張是別人的答案，但理想氣體的壓力不是比真實氣體的壓力低嗎？他是不是寫錯了

species A in the mixture at its final state. (2%) (3) Please describe Carnot's Theorem and the Third law of Thermodynar (4) Please describe the differences between ideal gas and real gas (2%) (5) In Van der Waals equation of state, please describe the meaning c briefly.(4%) (6) Please define Gibbs free energy (G), state the limiting factors and energy [3%]
