how much heat is required when 6.00g of water is melted at its melting point
q = mass H2O x heat fusion
To calculate the amount of heat required to melt a substance, you need to use the formula:
Q = m * ΔH
where:
Q is the heat energy,
m is the mass of the substance, and
ΔH is the heat of fusion (also known as the enthalpy of fusion).
In the case of water, the heat of fusion is 334 J/g.
Let's calculate the heat energy required:
Q = m * ΔH
Q = 6.00 g * 334 J/g
First, multiply the mass of water (6.00 g) by the heat of fusion (334 J/g):
6.00 g * 334 J/g = 2004 J
Therefore, 2004 Joules of heat energy is required to melt 6.00 grams of water at its melting point.
