How to Use This Calculator
- Select the mass of the substance using the dropdown menu.
- Choose the initial temperature of the substance.
- Select the desired final temperature.
- Click the “Calculate” button to see the results.
Formula & Methodology
The heat required (Q) to raise the temperature (ΔT) of a substance can be calculated using the formula:
Q = m * c * ΔT
where:
- m is the mass of the substance (in kilograms),
- c is the specific heat capacity of the substance (in joules per kilogram per kelvin), and
- ΔT is the change in temperature (in kelvin).
