Question

if you take a 1 liter bottle of water out of the refrigerator at just above 0 celsius., how much heat will it take to raise the water to 90 celsius, so you can make tea out of it.

Answer 1

Q = M*C*(T2 - T1)
= 1000 g * 1.00 cal/g C * 90 C
= 90,000 calories = 90 kilocalories

Answer 2

I am quite amazed. I appreciate your help!
