Family Traits, Thermal and Heat Energy, and Chemicals

Family Traits 👫

1. Inherited Traits: Traits passed from parents to children, like eye color or height.
   • Example: If both parents have brown eyes, their child might also have brown eyes.
2. Acquired Traits: Traits developed due to the environment or experiences.
   • Example: Learning to ride a bicycle or getting a scar from a cut.

Thermal Energy 🌡️

1. Definition: Energy that comes from heat.
   • Example: When you heat water, it gets warmer because of thermal energy.
2. Sources: Sun, fire, and even your body.
   • Example: The sun warms the earth with thermal energy.

Heat Energy 🔥

1. Definition: A form of energy that makes things warm or hot.
   • Example: Cooking food on a stove uses heat energy.
2. Transfer Methods:
   • Conduction: Heat moves through solid objects.
     • Example: A metal spoon getting hot from a boiling pot.
   • Convection: Heat moves through liquids and gases.
     • Example: Warm air rising and cool air sinking in a room.
   • Radiation: Heat moves through space without touching anything.
     • Example: Feeling the warmth from the sun on your skin.

Chemicals 🧪

1. Definition: Substances with specific properties used in reactions.
   • Example: Water (H₂O) is a chemical made of hydrogen and oxygen.
2. Uses: Cleaning, cooking, medicine, and more.
   • Example: Using vinegar (a chemical) to clean surfaces.
3. Safety: Handle with care, some can be dangerous.
   • Example: Always wear gloves and goggles when using strong chemicals.
