- Heat is a kind of heat energy
- Heat energy can change the state of matter
- So, heat can change the state of matter

- Heat can change the state of matter
- Liquid is a kind of state of matter
- Solid is a kind of state of matter
- So, heat can change a substance from a solid to liquid

- Heat can change a substance from a solid to liquid
- Melting means a substance changes from a solid into a liquid by increasing heat energy
- So, heat can cause a solid substance to melt

- Heat can cause a solid substance to melt
- Ice is a kind of solid
- Therefore, heat can cause ice to melt

- Heat can cause ice to melt
- A car engine is a source of heat
- Hence, the heat from a car engine can cause ice to melt

Hence, the heat from a car engine can cause ice to melt
Question: During winter months, Amina sometimes notices ice covering the hoods of parked cars. Once the engine of the car runs for a while, the ice on the hood begins to melt. What form of energy is released from the car engine to melt the ice?
