negative sign becauseΔHvalues are written for the system, and in this case, the system has lost 890 kJ of energy. The graph for this (figure 1) clearly shows that products have lower energy than the reactants hinting at the movement of this energy from the system to the surroundings. ...
(c) education (d) evolution Lewin's Equation: Kurt Lewin created the equation B = f(P, E) to explain human behavior in the form of a mathematical equation. However, the equation is more of a heuristic rather than an actual equation representing quantifiable r...
One method used to liquefy a gas lowers the temperature of the gas by causing it to expand and thereby to perform “P dV” work against its surroundings. If the expansion is adiabatic or nearly so, the work is done at the expense of the internal energy of the gas, and its temperature...
Calculate the enthalpy change of the following reaction: C(s) + 2S to CS_s (s) Using the following enthalpy value: C(s) + O_2 (g) to CO_2 (g) Delta E = -.393.5 kJ/mol S(s) + O_2 (g) to SO_2 (g) Delta E = -2958 kJ/mol CS(I)...
The MKI based shape-function possesses the Kronecker delta property. Li et al. in 2016 [110] proposed a new finite block method to investigate stress intensity factor and cracks at the interface for a 2D-fracture mechanics problem. The method employs Lagrange series interpolation in the strong-...

One of the equations you may encounter is the one for heat capacity: Q=mCΔT where Q is thermal energy in joules, m is the mass of the object being heated, C is the object's specific heat capacity and delta T is its change in te...
at heights can be dangerous if proper precautions aren’t taken. You must pay attention to your surroundings and be aware of potential hazards. The course also teaches you how to use safety equipment properly. This is important because it can help you stay safe in the event of an accident....
Delta G = Delta H-T Delta S is the equation for thermodynamics where Delta G is the free energy of the reaction. What determines if a reaction is spontaneous? A) The temperature only - reactions are only spontaneous at high temper...
