Heat (q) vs Mass of Solution/Substance

सूत्र

q = m × c × ΔT

Where:

q = heat absorbed or released (J)

m = mass (g)

c = specific heat capacity (J/(g·K))

ΔT = temperature change (K or °C)

Positive q means heat absorbed (endothermic). Negative q means heat released (exothermic).

100 g of water (c = 4.184 J/(g·K)) rises by 5 K.

What is calorimetry?

Calorimetry is the measurement of heat changes during chemical or physical processes using a device called a calorimeter.

Why use water in a calorimeter?

Water has a high specific heat (4.184 J/(g·K)), making it good at absorbing heat. Its properties are also well characterized.

What is the difference between q and ΔH?

At constant pressure, q = ΔH. In a bomb calorimeter (constant volume), q = ΔU (internal energy change), which differs slightly from ΔH.
