quantity of heat.

Yes, in this simple but extremely useful equation, Q stands for the amount of heat that is necessary to supply to a body or system to change its temperature from T2 to T1.
Note: T1 can be lower than T2. In this case the negative heat means heat to be "extracted" from the body.
Very, very common and useful equation used in engineering all the time.

Q is the amount of heat energy taken in or given off based on the temperature difference (T1 & T2), quantity of material (mass) and specific heat of that material (c).

Q stands for heat and is measured in Joules. m is for mass , c the specific heat capacity of the body. T1 will always be higher than T2

Q is the "heat" required to change temperature of mass (m)

this is a very common thermodynamic equation:
q=mct
where q: work done or energy
m: mass
c: specific heat
t: temperature

Q or E can also be used
it stands for energy
