It is a type of constant-volume calorimeter used in measuring the heat of
combustion or heating value of a particular reaction
(a)
Q in the formula Q=m⋅c⋅ΔT stands for?
(a)
What does the c in the formula for heat released stand for?
(a)
A type of calorimeter that incorporates modern technology, such as a digital temperature sensor with high resolution (22 bits), replacing the traditional glass tube thermometer used in a coffee cup.
(a)
It is a type of samples used in digital bomb calorimeter that can quickly evaporate.

The SI unit of energy.
(a)
A unit of heat energy. Specifically, the amount of heat needed to raise the temperature of one gram of water by one degree Celsius.
(a)
A unit used primarily in the United States. It represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
Joule (J)
Calorie (cal)
British Thermal Unit (BTU)
Calories per mole (cal/mol)
Though more commonly used to measure power, it's sometimes involved in calorimetry when measuring the rate of heat transfer. It is equal to one joule per second.
(a)
Pierre Eugene Berthelot developed the first modern bomb calorimeter.
True
False
Antoine Lavoisier and Pierre-Simon Laplace are the two French scientists are credited with the origins of modern calorimetry for their use of an ice calorimeter in the 1780s to measure heat and disprove the phlogiston theory.
True
False
Similar to a bomb calorimeter, the digital bomb calorimeter also uses a sealed bomb vessel.
