This equation simply states that the change in heat Q of a closed system (a liquid, gas or solid material) is equal to the mass m of the sample times the temperature change ΔT times a parameter C calledspecific
You can use the information in the last two sections along with one simple formula to calculate the heat absorption in a specific situation. All you need to know is the substance being heated, the change in temperature and the mass of the substance. The equation is: _Q_=mc∆_T_ Here,...

How to calculate the rate of reaction in chemistry? The half-life of a reaction of compound A to give compounds D and E is 7.20 min when the initial concentration of A is 0.200 mol/L.How long will it take for the concentration to drop to 0.0400 mol/L if the reaction is a first or...
Steps to Find Specific Heat Capacity Step 1: Identify the given values. Step 2: Calculate the specific heat capacity from the expression, c=ΔEmΔT, where m is the mass in Kg, ΔE is the energy required in J, and ΔT is the change in temperature in ∘C Equation and Definitio...
and theoretical modeling. Therefore, selecting a topic that is manageable in scope and supported by available resources is essential. Additionally, a good chemistry research topic should offer the potential for discovery and provide new insights into how substances interact, change, or behave under spe...
How to calculate enthalpy of vaporization?Heat of Vaporization:The heat of vaporization is the amount of energy associated with the phase change of 1 mol substance from liquid to gas at its boiling point. The unit of heat vaporization is kJmol....
How do you calculate free energy? Gibbs free energy, denoted G, combines enthalpy and entropy into a single value. The change in free energy, ΔG, isequal to the sum of the enthalpy plus the product of the temperature and entropy of the system. ...
This year, Cooper Tires is encouraging drivers to mark Labor Day weekend (and the first of every month) as a tire check safety moment, to make a habit of checking tires, especially as seasons change. "Just as we regularly take a moment to check our smoke detector batteries when we change...
Step 3: Substitute known quantities into the equation and calculate the unknown specific heat. We need to substitute known values into this equation, but first, we must calculate the change in temperature of both the water and the iron by subtracting the initial temperature of each from...
