Thermal energy flow from one system to other due to temperature gradient
When temperature gradient occurs it will have flow of energy from one to other
so here we can say
A calorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same TEMPERATURE.
A calorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same temperature.
Explanation:
In calorimeter, thermal energy flows from a material with higher or hotter temperature to a material with lower or colder temperature because it is based on the principle of temperature gradient due to change in temperature. When the materials possess the same temperature there will be no flow.
