比熱容（英語： specific heat capacity，符號c），簡稱比熱，亦稱比熱容量，是熱力學中常用的一個物理量，表示物體吸熱或散熱能力。 它指單位 質量的某種物質升高或下降單位溫度所吸收或放出的熱量。其國際單位制中的單位是焦耳每千克 開爾文[J/( kg · K )]，即令1公斤的物質的溫度上升1開爾文所需 ...
Q = mcΔT, (14.2.1) (14.2.1) Q = m c Δ T, where Q Q is the symbol for heat transfer, m m is the mass of the substance, and ΔT Δ T is the change in temperature. The symbol c c stands for specific heat and depends on the material and phase.
熱容量和比熱容量的定義(Definitions of Heat Capacity and Specific Heat Capacity) 將一個物體嘅溫度升高1 °C所需嘅能量。. 將1kg 嘅物質嘅溫度升高1 °C所需嘅能量。. 留意“熱容量”同“比熱容量”只係相差一個“比”字。. 仲記唔記得數學學過“率同比”? “比”喺係有 ...
\[Q = mc\Delta T,\] where \(Q\) is the symbol for heat transfer (“quantity of heat”), m is the mass of the substance, and \(\Delta T\) is the change in temperature. The symbol c stands for the specific heat (also called “ specific heat capacity ”) and depends on the material and phase.
Specific Heat Capacity of a Substance) 測定物質嘅比熱容量嘅方法係根據公式“ ”嚟做一個實驗。. E = mc∆T. 個實驗通常係用“加熱器”嚟將一個物體加熱。. 我哋只要將實驗數值代入公式中就可以計到個物質嘅比熱容量。. 一般嚟講,喺做實驗嘅時候, 加熱器所輸出嘅能量 ...
Q = mcΔT, where Q is the symbol for heat transfer (“quantity of heat”), m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for the specific heat (also called “ specific heat capacity ”) and depends on the material and phase.
q = mc\(\Delta T,\: \: \: c=\frac{q(J)}{m(g)\Delta T(K)}\) Note: Capital "C" is the Heat Capacity of an object, lower case "c" is the specific heat capacity of a substance. The heat capacity of an object made of a pure substance is, C=mc.
