Answer the following problems showing all work
Equation: ΔH = (m)(ΔT)(c) Other equations m = c = ΔT =
ΔT = TF - TI
where ΔH = energy flow/change of system
m = mass of system
c = specific heat of system _____________
TF = final temp
TI = initial temp
1. What is the specific heat (c) of a substance if the 84.1g of substance released 1984cal of energy while the temperature went from 76.3°C to 21.0°C? (6.28E3cal/(g-°C)) or 6280cal/(g-°C)) system __________
2. A container of water gains 532cal of energy and the temperature went from 28.2°C to 39.1°C. How many grams of water is there? (g or g ) system: __________
3. What is the temperature change (ΔT) of water if the water released 302J of energy for a mass of 211g of water. (2.36E3°C or 2360°C) system: __________
