Is specific heat C or Q?
Q = m•C•ΔT where Q is the quantity of heat transferred to or from the object, m is the mass of the object, C is the specific heat capacity of the material the object is composed of, and ΔT is the resulting temperature change of the object.

What is the C value in specific heat?
The nominal values used for air at 300 K are CP = 1.00 kJ/kg. K, Cv = 0.718 kJ/kg. K,, and k = 1.4.
Does aluminum heat up faster than steel?
“1kg of Aluminium requires twice as much energy to raise its temperature than 1kg of steel. However, aluminium has a larger thermal conductivity than steel. If a hot coin is placed on both an alminium slab and steel slab of same mass, which coin will cool faster.”
What is CP equal to?
Cp: In a system, Cp is the amount of heat energy released or absorbed by a unit mass of the substance with the change in temperature at a constant pressure. So, Cp represents the molar heat capacity, C when pressure is constant.
Is Q delta H?
Q is the energy transfer due to thermal reactions such as heating water, cooking, etc. anywhere where there is a heat transfer. You can say that Q (Heat) is energy in transit. Enthalpy (Delta H), on the other hand, is the state of the system, the total heat content.
What is the table of specific heat capacities?
The following table of specific heat capacities gives the volumetric heat capacity, as well as the specific heat capacity of some substances and engineering materials, and (when applicable) the molar heat capacity .
What is the specific heat of a liquid?
See also tabulated values for gases, food and foodstuff, metals and semimetals, common liquids and fluids and common solids, as well as values of molar specific heat for common organic substances and inorganic substances.
How is the specific heat of a metal expressed?
The specific heat is the amount of heat enregy per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat . Specific Heat Capacity Conversions: 1 Btu/(lb-°F) = 4186.8 J/(kg-°K)
How is specific heat used in constant pressure?
Specific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree. Isobaric specific heat (Cp) is used for air in a constant pressure (ΔP = 0) system.
