Final answer:
To melt 26 grams of ice, the heat required is calculated by multiplying the mass of the ice by the heat of fusion of water (334 J/g). The resulting calculation is 26 g multiplied by 334 J/g, which equals 8684 J.
Step-by-step explanation:
To calculate the heat in joules required to melt 26 grams of ice, we can use the heat of fusion of ice which is given as 334 J/g. The heat of fusion is the amount of energy required to change a solid into a liquid at its melting point without changing its temperature.
The formula used to calculate the energy required to melt the ice is:
Q = m × Lf
where:
Q = heat required (in joules),
m = mass of ice (in grams),
Lf = heat of fusion (in joules per gram).
We can substitute the given values into the equation:
Q = 26 g × 334 J/g
Q = 8684 J
Therefore, the heat required to melt 26 grams of ice is 8684 J.
