Worksheet: Heat and Heat Calculations Name 1. What is the difference in temperature and heat? i s of- how are el ìs an 2. energy is stored is energy in motion. energy and C be measured. can be measured. 3. When you heat a substance and the temperature rises, how much it rises depends upon its mass/ C 0m PO J 4.

Now, add the amount of heat (q) from each part of the answer. Total heat (q. T) = 12.54 kJ + 40.08 kJ + 6.15 kJ = 58.77 kJ. 6) How many joules are required to heat 75 grams of water from -85 ˚C to 185˚C? 251.845 kJ Start with Specific Heat because the water is frozen and must heat up from -85˚C to O˚C before it can go through a phase change ...

HEAT CALCULATIONS PRACTICE ANSWERS 1) How much heat is required to completely melt 75.0 g of ice at 273 K? Q = mH f x = (75.0 g)(334 J/g) X = 25050 J Æ 25100 J 2) How much heat is required to completely vaporize a 65.4 g sample of liquid water is

Worksheet- Calculations involving Specific Heat 1. For q= m c Δ T : identify each variables by name & the units associated with it. q = amount of heat (J) m = mass (grams) c = specific heat (J/g°C) ΔT = change in temperature (°C) 2. Heat is not the same as temperature, yet they are related. Explain how they differ from each other.

Q = 52.0 g x 4.184 J/goC x 67°C = 14577 J (Don’t round until end) Q = m x ΔH vap Q = 52.0 g x 2260 J/g = 117520 J Q = m x C x Δt Q = 52.0 g x 2.02 J/goC x 10°C = 1050.4 J (Note – a different C is used here because the chemical is steam, not liquid water.) add Q = 14577 J + 117520 J + 1050.4 J = 133,000 J

Worksheet heat and heat calculations answer key.

The heat evolved when 0.305 g of citric acid is combusted in the bomb calorimeter can be determined from the heat change and the heat capacity: q = C x T q = (1.71 kJ/°C)(1.83 °C) q = 3.13 kJ The molar mass of citric acid is 192.14 g/mol. The sample, 0.305 g, is equivalent to 1.59 x 10-3 mol. H combustion = q/moles H combustion
