In Chinese high school chemistry (compulsory), the pH of a neutral aqueous solution at 25°C is:
Answer: 7
At 25°C, pure water has [H⁺] = [OH⁻] = 10⁻⁷ mol/L, giving pH = -log[H⁺] = 7. This is the neutral point.
In Chinese high school physics (compulsory mechanics), if an object moves in a circle at constant speed, which of the following is true?
Answer: Its speed is constant but its velocity changes direction continuously
Uniform circular motion has constant speed but changing velocity direction. Since velocity changes (direction), there is centripetal acceleration and therefore a centripetal force.
According to the Chinese politics curriculum, the National People's Congress (全国人民代表大会) is best described as:
Answer: The highest organ of state power in China
China's Constitution designates the National People's Congress (NPC) as the highest organ of state power (最高国家权力机关). It exercises legislative power and elects major state leaders.
In Chinese compulsory history, the Long March (长征, 1934-1935) is significant primarily because:
Answer: It preserved the Red Army and CPC leadership, allowing them to reach northern base areas and continue the revolution
The Long March (about 12,500 km) saved the CPC and Red Army from KMT encirclement, allowed the Zunyi Conference to consolidate Mao's leadership, and enabled the CPC to establish a base in Yan'an.
In Chinese high school biology, the process by which a cell produces energy in the absence of oxygen is called:
Answer: Anaerobic respiration (fermentation)
Anaerobic respiration (无氧呼吸) occurs without oxygen. In animals and some microbes, glucose is converted to lactic acid or ethanol/CO₂, yielding a small amount of ATP.
China's geographic characteristic of '东西差异' (east-west differences) in the compulsory geography curriculum refers primarily to:
Answer: Differences in precipitation, economic development, and terrain moving from the humid eastern coast to the arid western interior
The east-west gradient in China involves increasing aridity and elevation moving westward, with the monsoon-influenced eastern regions being wetter and more economically developed, while the west is characterized by arid climate, high plateaus, and deserts.
