Question

How many kJ to hear 0.700 pint of room temp water to boiling

Answer 1

Use the equation Q = mCT.

Q is the amount of energy in joules.

m is the mass in grams.

C is the specific heat of water (4.184 J/g °C).

T is the change in temperature.

0.700 pints = 331.224 g of water

Q = (331.224 g)(4.184 J/g °C)(100° C - 30° C)

Q = 97,008.885 J

Divide by 1,000 to convert to kilojoules:

97.009 kJ
