What explains the key difference between a bomb calorimeter and a coffee cup calorimeter?.
Virty [35]

The key difference between a bomb calorimeter and a coffee cup calorimeter is high temperature.

<h3>What is bomb calorimeter?</h3>

A bomb calorimeter is an apparatus that can measure heats of combustion, used in various applications such as calculating the calorific value of foods and fuels.

<h3>What is coffee cup calorimeter?</h3>

A coffee cup calorimeter is a cup used to provide insulation when materials are mixed inside of it.

<h3>Difference between the two calorimeter</h3>
  • The coffee cup calorimeter can't be used for high-temperature reactions, either, because they would melt the cup.
  • A bomb calorimeter is used to measure heat flows for gases and ​high-temperature reactions
