How does physical fitness use calorimetry to measure calories burned during exercise?
Using heat production, or uptake of oxygen!
100.0 g of 4.0°C water is heated until its temperature is 37°C. Calculate the amount of heat energy needed to cause this rise in temperature.
14000 J
Who uses calorimetric data to measure calories burned?
Professional athletes
Which calorimeter is more difficult, constant pressure or constant volume?
A constant volume calorimeter is more difficult because it requires a well-built reaction container!
What mass of water will change its temperature by 3°C when 525 J of heat is added to it?
40 g
What is the most common field that uses calorimetric data?
