Calorimetry - Grade 10 ICSE — 7-topic bundle

You often hear "heat" and "temperature" used interchangeably, but in physics, they have very specific meanings. It's really important to distinguish between them.

Specific Heat Capacity (c) is the amount of heat energy required to raise the temperature of 1 unit mass of a substance by 1 degree Celsius (or 1 Kelvin).

Think about it this way:
* High specific heat capacity: The substance needs a lot of heat energy to change its temperature even a little. Water is a great example; it heats up and cools down slowly.
* Low specific heat capacity: The substance needs less heat energy to change its temperature significantly. Metals like copper heat up and cool down quickly.

When we talk about measuring heat changes, we need a special container that minimizes heat loss to or gain from the surroundings. That's where a calorimeter comes in.

A calorimeter is essentially an insulated container, often made of a good heat conductor like copper, placed inside another insulating jacket. Copper is chosen because it has a low specific heat capacity, meaning it absorbs less heat itself, making your measurements more accurate.
