Explanation

The properties used to describe heat are:

• Hot (high temperature)
• Energy (thermal energy)
• Cold (low temperature)

Explanation

• The trachea (windpipe) is a hollow tube in the chest.
• It connects the throat (pharynx) to the lungs, allowing air to pass through during breathing.

Explanation

When the half of the Earth is facing away from the Sun, it experiences Night, as it is not receiving direct sunlight.

• Wheels and axles (simple machine: wheel)
• Pedals and levers (simple machine: lever)
• Gears and pulleys (simple machine: pulley)
• Inclined planes (simple machine: inclined plane)

Explanation

• Heat is a form of energy that is transferred from one body to another due to a temperature difference.
• It is a type of kinetic energy that is transferred through the motion of particles.

Explanation

• Carnivores are animals that eat only meat, primarily from other animals.
• Examples of carnivores include lions, tigers, bears, wolves, and sharks.

Explanation

• Heat is measured in Joules (J), which is the unit of energy.
• Heat is a form of energy transferred from one body to another due to a temperature difference.
