Specific heat capacity (c) is the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius (or 1 kelvin). It measures how strongly a substance resists changes in temperature when heat is added. Water has a notably high specific heat capacity, which is why it warms and cools slowly.

比热容(c)是使 1 克物质温度升高 1 摄氏度(或 1 开尔文)所需的热量。它衡量物质在加热时抵抗温度变化的强弱。水的比热容显著偏高,这正是水升温和降温都缓慢的原因。
