2013年4月17日 · 一定质量的物质,在温度升高时,所吸收的热量与该物质的质量和升高的温度乘积之比,称做这种物质的比热容 (比热),用符号c表示。 其 国际单位制 中的单位是焦耳每千克 开尔文 [J / (kg·K) ]或焦耳每千克每摄氏度 [J / (kg·℃)]。 J是指焦耳,K是指 热力学温标,即令1千克的物质的温度上升(或下降)1开尔文所需的能量。 根据此定理,便可得出以下公式: 扩展资料: 比热容的单位是复合单位。 在国际单位制中,能量、功、热量的主单位统一为焦耳,温度的 …

3.12: Energy and Heat Capacity Calculations - Chemistry LibreTexts
The equation that relates heat (q) (q) to specific heat (cp) (c p), mass (m) (m), and temperature change (ΔT) (Δ T) is shown below. q = cp × m × ΔT q = c p × m × Δ T. The heat that is either absorbed or released is measured in joules. The mass is measured in grams.
Medium-chain triglyceride - Wikipedia
A medium-chain triglyceride (MCT) is a triglyceride with two or three fatty acids having an aliphatic tail of 6–12 carbon atoms, i.e. a medium-chain fatty acid (MCFA). Rich food sources for commercial extraction of MCTs include palm kernel oil and coconut oil.
Specific Heat Formula - Softschools.com
When heat energy is added to a substance, the temperature will change by a certain amount. The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate. heat energy = (mass of substance) (specific heat) (change in temperature) Q = heat energy (Joules, J)
為方便計數,我哋通常將Q 變成公式嘅Q = mc(T主項。 l 做有關熱容量嘅題目嘅方法基本上只係得一個:使用“能量守恆定律”, 然後解方程。 睇吓邊個物體會吸能量(即係睇吓邊件物體嘅溫度會升高)。 每個物體所吸收嘅能量 = = 當中ma = 物體嘅質量;ca = 物體嘅比熱容量m;Ta,Tfinal c (T = −物體最初同最終嘅溫度。 睇吓邊個物體會放能量(即係睇吓邊件物體嘅溫度會下降)。 c熱(T 其他物體 ))。 水嘅比熱容量係 4200JKg-1°C-1。 (唔 駛背!) 相比其他物質,水嘅比熱容量算係好高。 參考:鐵 …
Thermal Energy and Heat Transfer - Physics Forums
2006年5月28日 · I know the p= W/T and e=mct formulas but I'm having trouble with applying the 1000W to the heat transfer formulas. The other questions I've done,only required me to do mcΔt = -mcΔt with some latent fusion/vapourization in there. Confused where to start...
Does Unit Consistency Affect Calculations in the E = mcΔT Formula?
2011年4月4日 · Solving E=mc^2: What Units to Use? A Exact meaning of the mass M in the Kerr metric event horizon formula? Finding slip-off angle for mass off of sphere? This is probably a dumb question but, when calculating E = mct, if mass is in g, then c should be in J/g·°C right? Similarly, if mass is in kg, then c...
