### H and q

Is heat denoted with q or H? Or is H for heat and q is for enthalpy specifically?

### Re: H and q

I believe q denotes heat, which is basically a transfer of energy in chemical reactions. On the other hand, H is enthalpy, which is a state property.

### Re: H and q

q is the measurement for heat (in joules) and H is for enthalpy. While enthalpy is a state property (not dependent on the path taken to obtain that state), heat is not.

### Re: H and q

I think q typically denotes a change in heat energy while H denotes a change in enthalpy.

### Re: H and q

q is the denotation for heat (in joules), which is not a state property, and H is the denotation for enthalpy, which is a state property.

### Re: H and q

q is energy transfer while h(enthalpy) is total heat content or state of the system

### Re: H and q

q refers to heat whereas H refers to enthalpy. Enthalpy is known as a state function, meaning that if you knew the state of a reaction (how the reaction was before and after it occurred), the enthalpy can be calculated. On the other hand, heat is not a state function and cannot be calculated from the starting and ending states of a reaction.

### Re: H and q

H is for enthalpy and is a state property and q is not so it's for heat! Hope this helps :D

### Re: H and q

ΔH is for enthalpy, which is specifically the energy absorbed/released as heat by a system under constant pressure. It's a state function. Heat, q, is not a state function.

### Re: H and q

The symbol q is intended to express heat and H is to represent enthalpy is a state function while heat is not.

### Re: H and q

q represents the amount of heat released or absorbed in a system in J. Delta H represents the amount of heat released or absorbed AT CONSTANT PRESSURE. So you can think of it like q sub p = deltaH.

### Re: H and q

q is heat, while H is used to describe a change in enthalpy. As we discussed in class, enthalpy is a state function, while heat is focused more on heat released/absorbed from a system.

### Re: H and q

q is the heat that is transferred to or from a system, and it is not a state function. However, H is the total heat of the system at constant pressure and it is a state function.

### Re: H and q

I think q represents heat, but its not a state function. H is a state function that represents the net heat of a system at a specific pressure.

### Re: H and q

"q" denoted heat, while H represents enthalpy. If I am not mistaken, heat (q) of a gas under constant pressure equals the change in Enthalpy (H). Hope this helps!

### Re: H and q

Heat, which is not a state function, is denoted by q, while enthalpy, which is a change in heat at constant pressure, is a state function, and thus, it is denoted by delta H.

I believe q can also be used for enthalpy if it is qp or heat absorbed/released at constant pressure.

### Re: H and q

H is for enthalpy and q is for heat but when q is under constant pressure, q=h. This is because enthalpy relates to heat under the terms of constant pressure.

### Re: H and q

q is the measurement of heat (transfer of heat energy) and H is the measurement of enthalpy! Enthalpy is a state function but heat is not. If the system in question is at constant pressure, then I believe delta H is equal to q.
