10
Q
```SPECIFIC HEAT (SH)
* definition```
• how it is written
• how to write calculations using SH
A

Specific Heat (SH) is the amount of heat needed to raise the temperature of exactly 1g of a substance by exactly 1 degree C.

This temperature change is written as ∆T, where the delta symbol means “a change in”.
SH= heat/grams x ∆T = J (or cal)/ 1g x 1 ^oC

How to write calculations:
Heat = mass x ∆T x SH
