理想气体定律 / Ideal Gas Law
Temperature (温度 T)
Volume (体积 V)
Pressure (压强 P)
Moles (物质的量 n)
Temperature (温度)
Volume (体积)
Moles (物质的量)
演示要点 / Key points
T
温度决定分子速度
Higher T = faster molecules = more collisions
V
体积改变活塞位置
Larger V = piston rises = lower pressure
P
压强来自分子碰撞
P = nRT/V — pressure from wall collisions
n
物质的量决定分子数
More moles = more particles = higher pressure
