Question

Duncan knows that it takes 36400 cal of energy to heat a pint of water from room temperature to boiling. However, Duncan has prepared ramen noodles so many times he does not need to measure the water carefully. If he happens to heat 0.600 pint of room-temperature water, how many kilojoules of heat energy will have been absorbed by the water at the moment it begins to boil?

Answer 1

I think you can just multiply here.

Answer 2

And just remember that you have 3 significant figures to round your answer to.

Answer 3

Do you have the conversion factor for calories to kilojoules?

Answer 4

Your right. I converted kg to grams and multiplied. Thank You!
