Write a note about the sign convention of heat.

1.	Write a note about the sign convention of heat.
Answer» The symbol of heat is q. if the heat flows into the system from the surroundings, the energy of a system increases. Hence it is taken to be positive (+ q). if heat flows out of the system into the surroundings. energy of the system decreases. Hence it is taken to be negative (- q).
