Answer:

Q = 8.68 × 10⁴ J

Explanation:

We can calculate the heat required to melt a mass of ice, that is, to change it from the solid phase to the liquid phase, at a constant temperature of 0 °C, using the following expression.

Q = ΔH°f × m

where,

  • Q is the heat absorbed
  • ΔH°f is the standard enthalpy of fusion (ΔH°f for water: 334 J/g)
  • m is the mass of ice

Q = ΔH°f × m

Q = 334 J/g × 260 g

Q = 8.68 × 10⁴ J

Dylan changed a formless pile of sand into a sand castle. What other natural materials can be changed into art
amm1812

Other natural material such as clay, wood, and stones can be changed into art.

Clay is pliable and is very easy to be molded into different shapes and sizes.

Wood can easily carved into different shapes, also different patterns can be easily etched on wood.

Stones of different variety and from different geological sources are painstakingly converted into statues or portraits of different life forms and scenery.
