Why can specific heat capacity be stated in J kg K or J kg C with the same value?

The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C….Specific heat capacity.

Is kJ kg C the 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.

Is J kg K same as J KGC?

1 J/(kg*K) is 1 times smaller than a J/kg*°C.

Why does specific heat capacity change with temperature?

As the substance heats up, the average kinetic energy of the molecules increases. The collisions impart enough energy to allow rotation to occur. Rotation then contributes to the internal energy and raises the specific heat.

What is J kg C?

The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

What does J mean in specific heat capacity?

The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).

Why can temperature changes have units of either degrees Celsius or Kelvin?

You need the units because though x Kelvin is the same as x Celcius it is not the same as x Fahrenheit. You can treat ΔT as a temperature. A temperature scale has a fixed zero point (absolute zero for the Kelvin scale and the freezing point of water for the Centigrade scale) and an interval defining 1 degree.

What is the relation between specific heat and heat capacity?

The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT. Values of specific heat are dependent on the properties and phase of a given substance.

Why does the specific heat capacity of water or anything else have units of J CG?

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. The reason for this is because heat that is added or removed in a phase change does not alter the temperature.

What is the specific heat capacity of 1 kg of water?

Specific heat capacity. The SI unit of specific heat is joule per kelvin per kilogram, J/K/kg or J/ (K kg). For example, at a temperature of 25 °C, the heat required to raise the temperature of 1 kg of water by 1 K (equivalent to 1 °C) is 4 179.6 joules, meaning that the specific heat of water is 4.1796 kJ·kg−1·K−1.

What is the symbol for specific heat capacity?

The letter Q represents heat energy (with units of J or cal), the letter m represents mass (with units of g), the letter c represents specific heat capacity (with units of J/g C or cal/g C), and the symbol Δ T represents change in temperature (with units of C). What is a unit of specific heat?

What is the definition of heat capacity in physics?

In the International System of Units, heat capacity has the unit joules per kelvin (J/K). The heat capacity (symbol C) of a system is defined as the ratio of heat transferred to or from the system and the resulting change in temperature in the system, where the symbol δ designates heat as a path function.

What determines the amount of energy required to change the temperature?

The amount of energy required to change the temperature of a material depends on the specific heat capacity of the material. The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C).
