You take an ice cube (mass = 18g) from the freezer (t=-10°c) and place it on the table. later that day, you notice a puddle of water on the table that has reached ambient room temperature (20°c). how much heat must have been absorbed to make this happen? a) 1867.0 j b) 2260.4 j c) 7897.0 j d) 42657.0 j

The amount of heat absorbed or released by the system can be determined by the equation:

U = mCpΔT
where:
m = mass of material
Cp = specific heat capacity of material; in this case, Cpwater = 4.186 J/(g-°C)
ΔT = change in temperature of material

U = 18(4.186)(20-(-10)) = 2260.44 Joules or B.
A positive term means energy was absorbed.
