Answer 1

Okay, let's break this down step-by-step:

* We have 0.234 kg of ice

* Ice melts at 0 °C

* The latent heat of fusion of ice (the amount of heat needed to melt 1 kg of ice at 0 °C) is 333 kJ/kg

* So the amount of heat needed to melt 0.234 kg of ice is:

0.234 kg * 333 kJ/kg = 77.9 kJ

Therefore, it will take approximately 77.9 kJ of heat to melt a 0.234 kg ice cube at its melting point.
