1. When ice cubes are placed in water at a temperature of \(45^{\circ}C\), thermal energy is transferred from the water to the ice. This is because heat flows from a warmer object (the water) to a cooler one (the ice) until thermal equilibrium is reached.<br /><br />2. The symbol \(\Delta H\) stands for the change in enthalpy of a reaction. Enthalpy (\(H\)) is a measure of the total energy of a thermodynamic system, and \(\Delta H\) represents the difference in enthalpy between the products and reactants in a chemical reaction.
