The heat change for a chemical equation is the difference in enthalpy between the reactants and the products. It can be calculated by determining the sum of the enthalpies of formation for all the products and subtracting the sum of the enthalpies of formation for all the reactants. This value indicates whether a reaction releases heat (exothermic) or absorbs heat (endothermic).

Is described by the equation H2O(l) plus heat H2O(g)?
This is the a change of phase from liquid to gas.
What is the equation for calculating how much heat energy (calories) transferred to or from a mass of water.?
The equation is q = mC∆T where q is the heat; m is the mass of water; C is the specific heat of water (1 cal/g/deg); and ∆T is the change in temperature.
What is the equation relating temperature heat and specific heat capacity to each other?
The equation relating temperature change (∆T), heat energy (Q), and specific heat capacity (c) is Q = mc∆T, where Q is the amount of heat energy transferred, m is the mass of the substance, c is the specific heat capacity, and ∆T is the temperature change.
What equation indicates an endothermic equation?
An endothermic reaction occur with heat absorption.
What is the solution to the Heat equation using fourier transform?
The solution to the Heat equation using Fourier transform is given by the convolution of the initial condition with the fundamental solution of the heat equation, which is the Gaussian function. The Fourier transform helps in solving the heat equation by transforming the problem from the spatial domain to the frequency domain, simplifying the calculations.
Where does heat appear in the equation?
Heat appears in the equation as either a reactant (if heat is added to the reaction) or as a product (if heat is released by the reaction). It is typically denoted by the symbol "ΔH" for the change in enthalpy.
What is the title of the chemical equation that includes the heat change?
Law of Thermodynamics
What s the correct equation rearranged to solve for specific heat?
The correct equation to solve for specific heat is q = mcΔT, where q represents heat energy, m is mass, c is specific heat capacity, and ΔT is the temperature change. Rearranging the equation to solve for specific heat, we get c = q / (mΔT).
What is the enthalpy equation used to calculate the change in heat energy of a system at constant pressure?
The enthalpy equation used to calculate the change in heat energy of a system at constant pressure is H q PV, where H is the change in enthalpy, q is the heat added or removed from the system, P is the pressure, and V is the change in volume.
What can specific heat be used to measure change in?
Specific heat can be used to measure changes in thermal energy by using the equation: Change in thermal energy = mass x Change in temperature x specific heat
The change in energy represented by a thermochemical equation is always?
The change in energy represented by a thermochemical equation is always given in units of energy, typically kilojoules (kJ) or kilocalories (kcal), and can be either exothermic (releasing heat) or endothermic (absorbing heat).
What equation represents the energy it takes to heat a sunstance?
The equation that represents the energy required to heat a substance is Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
What is the formula for finding the mass in specific heat?
The formula for finding mass using specific heat is: mass = (heat energy)/(specific heat x change in temperature). This formula is derived from the specific heat equation, q = mcΔT, where q represents heat energy, m is mass, c is specific heat, and ΔT is the change in temperature. By rearranging the equation to solve for mass, we can determine the mass of a substance based on the amount of heat energy supplied, the specific heat capacity of the material, and the resulting change in temperature.
What is the equation for meausuring the change in thermal energy?
The equation for measuring the change in thermal energy is: Q = mcΔT, where Q is the change in thermal energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
What equation represents the energy it takes to heat a substance?
Q=mc∆T
For the specific heat capacity equation q equals m x C x Δt does change in temperature always have to be positive?
No, the change in temperature does not always have to be positive in the specific heat capacity equation. It can be positive if the temperature increases or negative if the temperature decreases. The sign of the change in temperature (Δt) will depend on whether heat is being added or removed from the system.
Is described by the equation H2O(l) plus heat H2O(g)?
