Specific Heat of Water When one boils water in a metal vessel, one notices that while the metal vessel is too hot to touch within seconds, the same is not true for the water. Instead, the water might be lukewarm or even colder in the initial 30 seconds. This contrast in observation is...
Heat Capacity:Heat capacity is stated as the proportion of heat needed to increases the temperature to the unit degree of temperature including its unit mass of the material. The unit of heat capacity is joule /Kelvin.Answer and Explanation: The heat capacity and temperature are...

Therefore, the calculated value of specific heat has a tolerance of about 5.4% yielding a final result of 4.4 +/- 0.2 J/g/degreeC. Step 5: Conclusion In this experiment, the specific heat of water was measured by heating a small quantity of water with a known power input, and measuring...
Specific heat capacity is the amount of heat required to raise the temperature of a particular substance of mass (kilogram, gram, pound) by 1 degree (celsius, fahrenheit, kelvin). For example, the heat capacity of water is 4186 joules/kilogram celsius. It means that the heat energy required...

也就是说不同的物质,其 specific heat capacity 不一样。 水(water)的specific heat capacity (单位热容 c )为 4.2 x 103J/(kg・oC). 铜(copper)的单位热容是 0.39 J/(kg・oC). 下表是常见物质的单位热容: Table of common specific heat capacity(常见物质单位热容)...
Specific Heat – the amount of heat it takes to raise the temperature of 1g of the substance 1○ C. Each substance has its own specific heat (Cp), including water, ice, steam. Cp = q heat (joules or calories) m X ΔT mass (g) X change in temp (C) ...
SI unit of specific latent heat of vapourization,, of a substance isjoule per kilogram () Latent Heat In Terms Of Molecular Behaviour Latent heat energy is absorbed or given out while a substance undergoes state change. The average kinetic energy of the molecules does not change so that the...
Understanding Specific Heat: Specific heat is a fundamental property of matter that quantifies the amount of heat energy required to raise the temperature of a given substance by a certain amount. Different materials have different specific heat capacities, and these are expressed in various units,...
