Calculate the energy required to heat of ethanol from to . Assume the specific heat capacity of ethanol under these conditions is . Be sure your answer has the correct number of significant digits.

17 kJ

Explanation:

Calculation for the Calculate the energy required to heat 0.60kg of ethanol from 2.2°C to 13.7°C.

Using this formula

q = mC∆T

Where,

q represent Energy

m represent Mass of substance=0.60kg=600g

C represent Specific heat capacity=2.44J·g−1K−1.

∆T represent change in Temperature=2.2°C to 13.7°C.

Let plug in the formula

q=(0.60 kg x 1000 g/kg)(2.44 J/gº)(13.7°C-2.2°C)

q = (600g)(2.44 J/gº)(11.5º)

q=16.836 kJ

q= 17 kJ (Approximately)

Therefore the energy required to heat 0.60kg of ethanol from 2.2°C to 13.7°C will be 17 kJ

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
