When water at 0°C freezes to form ice at the same temperature of 0°C, then it:

The boiling point of ethane is, -88°C. This temperature will be equivalent to:

When heat is constantly supplied by a gas burner with small flame to melt ice, then the temperature of ice during melting:

When heat is constantly supplied by a burner to boiling water, then the temperature of water during vaporisation:

The latent heat of fusion of ice is:
