measurement-of-enthalpy-and-internal-energy-change
The enthalpy of a system is a measure of the heat content of the system. It is defined as the heat energy released or absorbed by the system when it undergoes a change in state. The internal energy of a system is a measure of the total energy of the system. It is the sum of the kinetic and potential energy of the particles in the system. The internal energy of a system can change when the system undergoes a change in state, when the temperature of the system changes, or when the number of particles in the system changes.
What is Enthalpy?
The enthalpy of a system is a measure of the system’s internal energy and the work done on the system. The enthalpy of a system is the sum of the system’s kinetic energy and the system’s potential energy.
What is Internal Energy?
Internal energy is the total energy of all the particles in a system. It includes the kinetic energy of the particles and the potential energy of the particles’ interactions.
Enthalpy Change Measurement
The enthalpy change of a reaction is a measure of the heat absorbed or released in the reaction. The enthalpy change can be measured using a calorimeter, which is a device that measures the heat flow between a system and its surroundings. The enthalpy change is equal to the heat flow multiplied by the time the reaction takes place.
Strategies:
1. If your opponent is pressuring you with a lot of small creatures, use your removal spells to clear the board.
2. If your opponent has a large creature, use your removal spells to take it down.
3. Play a lot of creatures of your own to create a board presence and overwhelm your opponent.
4. Use your card draw spells to find the right cards for the situation.
Solution:
We can solve this problem using the Quadratic Formula.
\begin{align*}x&=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ &=\frac{-1\pm\sqrt{1-4(1)(-1)}}{2(1)}\\ &=\frac{1\pm\sqrt{5}}{2}\\ &=\frac{1\pm\sqrt{5}}{2}\end{align*}
Therefore, the solutions to the equation are \begin{align*}x=\frac{1\pm\sqrt{5}}{2}\end{align*}.
