Specific Heat Calculator
🔥 Thermochemistry & Bonding. Use the Specific heat formula to find heat, mass, specific heat c, temperature change: pick the value you want, type the others, and the answer updates as you go.
Water: c = 4.18 J/(g·°C). From the lab: the liquid mass and its rise above 20 °C.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Heat | J |
| Mass | g |
| Specific heat c | J/(g·°C) |
| Temperature change | °C |
Worked example
Find the heat when Mass = 100 g, Specific heat c = 4.18 J/(g·°C), Temperature change = 50 °C.
Using q = mcΔ T: Heat = 20900 J.
Frequently asked questions
What is the formula for Specific heat?
q = mcΔ T. Water: c = 4.18 J/(g·°C). From the lab: the liquid mass and its rise above 20 °C.
What do the letters stand for, and what units are used?
Heat in J, Mass in g, Specific heat c in J/(g·°C), Temperature change in °C.
How do you calculate heat?
Put the values into q = mcΔ T. For example, with Mass = 100 g, Specific heat c = 4.18 J/(g·°C), Temperature change = 50 °C, heat = 20900 J.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (heat, mass, specific heat c, temperature change) and fill in the others: it rearranges the formula for you.
