Is kJ kg C same as kJ kg K?
Assuming you mean kJ/(kg K) and kJ/(kg C), where K stands for a unit on the Kelvin temperature scale and the C for a unit on the Celsius temperature scale, the answer is yes because the Celcius and Kelvin scale have the same unit but different zero points. Normally we use K.
What is the specific heat of water in kJ kg C?
4.187 kJ/kgK
Specific heat (Cp) water (at 15°C/60°F): 4.187 kJ/kgK = 1.001 Btu(IT)/(lbm °F) or kcal/(kg K)
Is specific heat same in C and K?
The specific heat capacity is the heat needed to raise the temperature of 1g of substance by 1 degree Celsius. 1 degree Celsius=1 degree Kelvin. When solving specific heat capacity in Kelvin, Kelvin=Celsius because the distance from one degree to the next degree in both Celsius and Kelvin is the same.
What is the heat capacity of water in kilojoules per kilogram per degree Kelvin kJ kg K )?
4.184 KJ/Kg
The specific heat of liquid water is 4.184 J/g, which is also 4.184 KJ/Kg.
How do you convert kJ to kW?
To convert a kilojoule measurement to a kilowatt-hour measurement, divide the energy by the conversion ratio. The energy in kilowatt-hours is equal to the kilojoules divided by 3,600.
How do you calculate the heat capacity of water?
The specific heat capacity of water is 4.18 J/g/°C. We wish to determine the value of Q – the quantity of heat. To do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from the initial and final temperature.
What is K in heat capacity?
Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 kelvin (SI unit of specific heat capacity J kg−1 K−1).
What is C in heat capacity?
An object’s heat capacity (symbol C) is defined as the ratio of the amount of heat energy transferred to an object to the resulting increase in temperature of the object. C=QΔT. C = Q Δ T .
How do you calculate joules to heat water?
Answer: The specific heat capacity of water is (roughly) 4.184 kilojoules / kg K. (10 kg) × (40 degrees Celsius temperature change) × (4.184 kJ / kg K) = 1673.6 kilojoules.
What is a kJ kg?
kJ/kg means kilojoules per kilogram, a metric unit of measure used to describe the amount of heat released on combustion of one kilogram of combustible material, such as coal, under specific conditions.
How do you calculate heat capacity?
Finding the heat capacity of something comes down to a simple formula — just divide the Amount of Heat Energy Supplied by the Change in Temperature to determine how much energy was needed per degree. Every material in the world has a different heat capacity.
What is the formula for specific heat capacity?
Heat capacity formula. The formula for specific heat looks like this: c = Q / (m * ΔT) Q is the amount of supplied or subtracted heat (in joules), m is the mass of the sample and ΔT is the difference between the initial and final temperature of the sample.
Which units express specific heat capacity?
The SI unit of heat capacity is joule per kelvin (J/K). Heat capacity is an extensive property. The corresponding intensive property is the specific heat capacity.
What are the units of specific heat capacity?
In SI units, specific heat capacity (symbol: c) is the amount of heat in joules required to raise 1 gram of a substance 1 Kelvin. It may also be expressed as J/kg·K. Specific heat capacity may be reported in the units of calories per gram degree Celsius, too.
