Energy, E.
There are two types of chemical reactions. Reactions which produce energy are called exothermic reactions, while reactions which consume energy are called endothermicreactions. Generally, an exothermic reaction can be written such as Reactants → Products + Energy An endothermic reaction can be written such as: Reactants + Energy → Products

What symbol indicates a low pressure system?
A L is used to indicate a low pressure system
Are anticyclones low pressure system?
No, an anticyclone is a high pressure system. A cyclone is a low pressure system.
Why is a low-pressure system called a low-pressure system?
In a low pressure system, the air pressure, which is the force with which the air presses down, is lower than what it normally is. Hence, it is called a low-pressure system.
What type of pressure system is a tornado?
A tornado produces low pressure, but it is not a pressure system in and of itself.
What weather system causes pressure to drop?
A Low Pressure System
Choose the name and symbol for internal heat of a system at constant pressure?
enthalpy, H
Is the heat content of a system at a constant pressure?
Yes it is possible, for example when water freezes there is a point when the temperature remains constant however energy is released as the water condenses.
What symbol indicates a low pressure system?
A L is used to indicate a low pressure system
How is the pressure and absolute temperature of a gas at constant volume related?
It is change in internal energy. If the volume of the system remains unchanged (isochoric process)then the heat given to the system is entirely utilized to increase the internal energy of that system. It is to be noted that no pressure-voulme work is done in such processes.
The heat content of a system at constant pressure?
Enthalpy
What color is the symbol for the high pressure system?
red and low pressure is blue
Why pressure vessel required for booster pump?
To maintain constant pressure in the plumbing system
What happens to a gas temperature at a given pressure?
In a closed system with constant pressure and no input or output of heat, the gas temperature will remain constant. In that same system, if the pressure is increased, then the gas temperature will also increase. If pressure is decreased, then the gas temperature will decrease.
Does internal energy of system depends upon volume?
Internal energy is an extensive state function. That means it depends on how much of a substance you have but if you fix the composition, pressure, temperature, volume, and (in the case of a system at a phase equlibrium point, like water at the freezing point) the phase of a system, the specific internal energy will be constant. If you take a closed system and change the volume of it, you will be doing work (or allowing the system to do work) and the internal energy can change - so - yes - internal energy of a system depends upon volume. Also, if you fix the composition, temperature, pressure, and phase of a homogeneous mass but change the volume, you will increase the amount of mass you included in the system, thus changing the total internal energy (because it is, after all, an extensive function).
What is heat of enthalphy?
Enthalpy H is a thermodynamic state function, that is defined for homogeneous systems as H = U + P V where U is the internal energy of the system, P the pressure and V the volume. If we perform a transformation of the system between the states 0 and 1 maintaining the pressure constant, for the first thermodynamic principle, we have U1 - U0 = Q - P (V1 - V0) where Q is the heat the system absorbs during the transformation. From the definition of enthalpy we also have H1 - H0 = U1 - U0 + P (V1 - V0) Putting together the last two equations we get that, if pressure is maintained constant, H1 - H0 = Q that is the variation of enthalpy is equal too the heat absorbed during the transformation. Naturally this is not true if the pressure is not constant, but the case of constant pressure is particularly important since almost all chemical equations happen at constant pressure.
What is the symbol for a flat tire on the dashboard?
Low tire pressure or tire pressure system malfunction
