The answer that the homework assigned wanted was (580 cal/g)(400g) = 232,000 cal = 971,105.60 J Heat Transfer equation: q=mc(dT) Energy = (mass) x (specific heat) x (change in temp) m = 400 grams c (of H20) = 4.186 Joules/gram (you just look up this value) dT = 100°C-25°C (assume water evaporates at 100°C, so change in temp is T(final) - T(initial) q = 400g x 4.186J/g x 75°C q= 125,580 J = 125.6 KJ

Temperature at which water changed from solid to liquid?
Water changes state from liquid to solid when it reaches a temperature of 0 degrees Celsius, or 32 degrees Fahrenheit. This is a simple example of changing from liquid to solid, or freezing.
What is 76 degrees in Celsius?
76 degrees Fahrenheit = 24.44 degrees Celsius
Calculate 98.6 degrees Fahrenheit into Celsius?
98.6 degrees Fahrenheit = 37 degrees Celsius.
What temperature does water evaporate and what temperature does water freeze?
in atmospheric pressure water evaporates at 100 degrees Celsius and freeze at 0 degrees Celsius. This may vary based on pressure
What are the stages in Celsius from freezing to evaporation?
Pure water at standard sea-level pressure freezes at zero (0) degrees Celsius and boils at 100 degrees Celsius. Between 0 and 100, water will evaporate but not boil.
Calculate 5 degrees Fahrenheit to Celsius?
-15 C
What happened to the temperature of the water as the water boiled?
It rose to 100 degrees Celsius. The water starts to evaporate?

80cal/g
How do you calculate 3 K to celsius?
3 K is equivalent to -270,15 Celsius degrees.
The temperature required to boil water at?
100 degrees Celsius
Water evaporate at?
Depends on the pressure. The normal boiling point (at 1 ATM of pressure) is 100 degrees Celsius.
