What is the formula for calculating heat energy when there is a change in temperature.

Q = m.c. ΔT

Explanation:

When temperature is changed the heat evolved or absorbed are calculating by following formula.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

When temperature is decreased heat is evolved and negative sign is added into Q value.

When temperature is increased heat is absorbed by system and positive sign is added with Q value.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
