## How do I calculate specific heat?

The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m) .

**What formula uses specific heat?**

Specific heat is the amount of heat required to raise one gram of any substance one degree Celsius or Kelvin. The formula for specific heat is the amount of heat absorbed or released = mass x specific heat x change in temperature.

**How is ΔT calculated?**

To do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from the initial and final temperature.

### What is Q Q MC?

Q = mc∆T. Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) ∆ is a symbol meaning “the change in”

**What is the formula for calculating specific heat?**

Specific heat refers to the amount of heat required to raise unit mass of a substance’s temperature by 1 degree. The Specific Heat formula is: c = ΔQ / (m × ΔT)

**What are the correct units to use for specific heat?**

The SI unit of specific heat is joule per kelvin and kilogram, J/ (K kg). For example, at a temperature of 25 °C the heat required to raise the temperature of 1 kg of water by 1 K is 4 179.6 joules so the specific heat capacity of water is 4 179.6 J·kg−1·K−1.

#### What must equations be used to calculate heat?

To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change in temperature of the liquid (degrees Celsius).

**What are units for measuring specific heat?**

One of the units of measurement for heat is the joule. Heat is usually measured with a calorimeter, where the energy in a material is allowed to flow into nearby water, which has a known specific heat capacity.
