The relationship between the change in enthalpy (H), specific heat capacity (Cp), and temperature change (T) in a system is described by the equation H Cp T. This equation shows that the change in enthalpy is directly proportional to the specific heat capacity and the temperature change in the system.

The relationship between heat transfer (h), specific heat capacity (c), and temperature change (T) is described by the equation: h c T. This equation shows that the amount of heat transferred is directly proportional to the specific heat capacity of the material and the temperature change.
The enthalpy of air at 700 kPa and 450 K can be determined using specific enthalpy values for these conditions from thermodynamic tables or equations. Without specific values, it is not possible to provide an exact answer.
When heat is transferred in a space the average energy of the particles - the temperature of the substance - is affected, by increasing or decreasing. The change in temperature depends on the number of particles affected.
In the equation qcvt, q represents the amount of heat transferred, c is the specific heat capacity of the material, m is the mass of the material, T is the change in temperature, and t is the time taken for the heat transfer to occur. These variables are related in the equation that shows how heat transfer is influenced by the specific heat capacity, mass, change in temperature, and time.

The enthalpy of 17-4 PH stainless steel, like other materials, is not a fixed value and can vary depending on the temperature and phase of the material. Typically, the specific heat capacity for stainless steels is around 500 J/kg·K, which can be used in conjunction with temperature change to estimate enthalpy changes. For precise enthalpy values, reference to material property databases or specific experimental data is necessary.

the standard enthalpy change of vaporization DHov is the enthalpy change when one mole of a substance is transformed into a gas enthalpy change is the term we use to describe the energy exchange that occurs with the surroundings at a constant temperature and pressure so to work it out, use the formula DH = cmDT DH - the enthalpy change c - the specific heat capacity of butanol (kJ kg-1 °C-1) m - the mass of butanol heated (kg) DT - the change in temperature of the butanol (°C) so there is no general enthalpy change of butanol, it depends on the factors above. the specific heat capacity of butanol, the mass of butanol heated, and the change in temperature of the butanol should be given to you in order to work the enthalpy change of vaporization of butanol if there is a rise in temperature, the reaction is exothermic and if there is a drop in temperature the reaction is endothermic. exothermic reactions have a negative enthalpy change, and therefore endothermic reactions have a positive enthalpy change. hope it helped (:

The enthalpy change can be calculated using the formula q = mcΔT, where q is the heat absorbed by the water, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the temperature change. Once you calculate q, you can use the relationship ΔH = q/moles of compound to find the enthalpy change.
To determine the molar enthalpy of a reaction, one can measure the heat released or absorbed during the reaction using a calorimeter. By knowing the amount of reactants used and the temperature change, the molar enthalpy can be calculated using the formula q mCT, where q is the heat exchanged, m is the mass of the substance, C is the specific heat capacity, and T is the temperature change.
The molar enthalpy change for heating a substance can be calculated using the formula: ΔH = nCΔT, where n is the number of moles, C is the molar heat capacity, and ΔT is the temperature change. Without specific values for n and C, the molar enthalpy change cannot be determined.
Enthalpy is the amount of energy in a system and when this changes (when a reaction happens), the energy is either released (exothermic) or absorbed (endothermic) and this energy is usually released or absorbed as heat. Therefore when the enthalpy decreases, heat is released from the system making it exothermic. In contrast, when the enthalpy increases, heat is absorbed making it endothermic.
specific heat capacity
All quantitative variables will be reduced including: Internal energy Enthalpy Gibbs energy Volume Mass Moles All intensive properties will remain unchanged including: Specific internal energy Specific enthalpy Specific Gibbs energy Specific volume (and its reciprocal density) Temperature Pressure Heat capacity Elasticity Conductivity etc.
This formula relates heat (Q) with mass, specific heat, and temperature change. It is typically used to calculate the amount of heat energy gained or lost during a temperature change in a system. The formula shows that the heat exchanged is directly proportional to the mass of the substance, its specific heat capacity, and the temperature change.
