What do these two changes have in common? boiling sugar to make caramel an engine using gasoline to power a car Select all that apply. Both conserve mass. Both are chemical changes. Both are caused by heating.

All three statements apply to both processes: 1. **Both conserve mass.** - In **caramelizing sugar**, the mass of the sugar is transformed into caramel, but the total mass remains constant. - In an **engine using gasoline**, the mass of the gasoline and oxygen is converted into exhaust gases and energy, conserving mass overall. 2. **Both are chemical changes.** - **Caramelization** involves the chemical transformation of sugar molecules into new compounds, changing its structure and properties. - **Combustion of gasoline** in an engine is a chemical reaction where gasoline reacts with oxygen to produce carbon dioxide, water, and energy. 3. **Both are caused by heating.** - **Boiling sugar** to make caramel requires heating to initiate the chemical reactions. - In an **engine**, the combustion process is initiated by the heat generated from igniting the gasoline-air mixture, often facilitated by spark plugs. **Therefore, all of the following apply:** - Both conserve mass. - Both are chemical changes. - Both are caused by heating.
